0:05hey guys it's Tim here and today I'd
0:07like to announce the official release of
0:09my caob course over at cubing Dogg the
0:12goal of this course is to meet you
0:13wherever you are at in your caob journey
0:16so whether you're a beginner
0:17intermediate solver or a pro cuber there
0:18will be something of value in this
0:20course for you in today's video I'd like
0:22to give you a taste of what the course
0:23has to offer by showing you five areas
0:25that hold people back in their f2l
0:27solving so hopefully by the end of this
0:29video you'll have an idea of what's
0:31stopping you from improving and you'll
0:32have a plan on how to move forward let's
0:34get started so reason number one is not
0:37knowing the best solutions for each f2l
0:38pair so when you first learn f2l it's
0:41most likely you learned it using an
0:43intuitive method which is good but once
0:45you're comfortable with that you should
0:46start learning algorithms for each pair
0:48so that you know exactly what to do when
0:50you see that pair so if you're using
0:51intuitive s2l you might find that you're
0:53doing a lot of rotations for each pair
0:55you might find that you're also doing
0:57unnecessary triggers and you're not sure
0:59what you're really doing of them so as
1:01an example we have this Paar and uh this
1:04is a Paar that takes a lot of moves to
1:05solve but just knowing one solution
1:07that's good for this pair will make you
1:09very confident every time you see this
1:11pair and so then you can solve it
1:12quickly also learning a specific
1:14solution for each f2l case will help you
1:17to develop good look ahead because each
1:19time the way the pieces are moving
1:20around the cube is the same so over time
1:22you'll memorize how each piece moves
1:24when you do that algorithm so as an
1:26example of a case you might encounter
1:28this pair you split the pair with R U2 R
1:32Prime and then you solve this case with
1:35r u r Prime and then you just insert the
1:39slot another example is when you have
1:42this pair in the back this is generally
1:44a hard pair but it's even worse when you
1:46get it in the back slot so the way to
1:48deal with this is you put it over here
1:51do a soon and then you insert it
1:54here another example is this pair right
1:57here where the corner is solved and the
1:58EDG is in the top layer so this is a
2:01difficult case because there's just no
2:02good solutions for it but one that I
2:05recommend is fime then solving the fre
2:09remover which breaks the cross but you
2:11solve it with r u r Prime and then you
2:14insert this cross piece back with u
2:16Prime RP Prime f r so your goal should
2:20be to be able to do each pair from every
2:23angle or at least have an idea of what
2:25your ideal solution is for every angle
2:27of every pair but at the start that
2:29might seem very daunting so just to
2:31start learn each f2l case for the front
2:34right slot when it's oriented and then
2:36you can move on to other slots from
2:38other angles later so to find good f2l
2:40Solutions I'd recommend my cop course
2:43airing. as it's all of the algs I
2:45recommend I go over all angles and all
2:47the weird dials you can do for back
2:49slots and side slots stuff like that a
2:51free resource is looking over top Q Rec
2:54constructions however that does make it
2:55pretty difficult to find the specific Al
2:58you're looking for so the course is a
2:59really good good resource to find
3:01whatever weird case you're looking for
3:03really quickly so reason number two is
3:05not using Keyhole Keyhole is a very
3:07useful technique for f2l which allows
3:09you to do XC crosses very easily and it
3:11just helps you deal with really bad
3:12cases in the middle of f2l so Keyhole is
3:15pretty much where you have one piece
3:16already solved and the other piece is in
3:18the top layer usually and then you
3:21misalign the D layer so that the free
3:23slot is over another free slot and then
3:26this allows you to insert the piece in
3:28the top layer into that free slot then
3:31you can undo the D move and you solve
3:33the pair normally this would take a lot
3:36more moves as this corner is in the slot
3:39and it's kind of blocking your way into
3:40the slot so you might have to do
3:42something like this which is a lot more
3:45moves so here's another example where I
3:48can use Keyhole to make an xross uh so
3:52this Edge is solved with this corner
3:54attached to it and this red Edge is also
3:56solved so we just need to solve this
3:58Edge and this Edge and and then ideally
4:01I want to solve the edge that
4:02corresponds to this corner as well so
4:04then I get a free pair at the start of
4:06F12 so to do that I can solve this uh
4:08edge with an L2 and I can insert this
4:12Edge and then the edge that corresponds
4:15to the corner is right here and we
4:16already have the cross Miss aligned so
4:19since this is not solved either the
4:21corner Deco between these two edges I
4:23can just use this free slot to insert
4:25this Edge then I can align the cross and
4:28I have an xross so the next reason is
4:30bad look ahead the idea of look ahead is
4:33that while you're solving one thing
4:35you're looking ahead to the next thing
4:37you're going to solve so as an example I
4:39finished my xcross and I want to solve a
4:42second pair so I look at this pair and
4:45now that I've identified what the pair
4:47is I can immediately start ignoring it
4:50just solve it by muscle memory and while
4:52I'm doing that I'm trying to find my
4:54next pair so in this case I see this
4:56piece and this piece so I'm tracking
4:59those two while I'm doing the first pair
5:02so this Edge is going here and the
5:04corner is back here and then I can
5:07immediately rotate and start doing the
5:09next pair and I can just keep doing that
5:11for the whole s so this allows you to
5:14pause way less during solves and if you
5:16have perfect look ahead I guess you
5:18don't pause at all but that's pretty
5:19rare so the first thing you need to do
5:22to be able to like start practicing look
5:24ahead is make sure you know how you're
5:27going to solve each pair so that ties
5:29into our first point you just need to
5:30know all of your Solutions or you just
5:32need to be able to do your pairs blind
5:34but it's pretty hard to do that without
5:35knowing the algs so as an example I can
5:38look at this pair and close my eyes and
5:41just do it and it's solved so once you
5:44can do that that means that if you have
5:46a pair instead of closing your eyes you
5:48just move your eyes to the next pair and
5:50start tracking it so it's right here so
5:53once you're able to do pairs blindfolded
5:55you should move on to doing solves where
5:57let's say you predict your cross so here
6:00uh I predicted that I need to do D Prime
6:02RP Prime to solve this piece and then
6:04I'll solve this piece and this piece
6:06with U2 L Prime frime L and then align
6:10the cross with d so then while I'm doing
6:13that I'm not looking at the cross I'm
6:15just looking for my next pair so I see
6:17this piece I see this
6:19piece and they're going to end up here
6:22and here so then I'm going straight into
6:25that and while doing that I'm not
6:27looking at those pieces I'm looking for
6:28this pair
6:30and then while I'm doing that pair I'm
6:32looking for this piece and trying to
6:34find the other one so then I see it's
6:36here and then while I'm doing this pair
6:39I'm looking at this piece and this
6:42piece and I just do that for all of us2
6:45and then you can even try doing it for
6:46last layer but it's much harder cuz
6:48there are more pieces to track another
6:50drill you can try is doing one pair and
6:53then trying to predict where your next
6:55pair is going to be before you start
6:57doing that so I'm going to do this pair
6:59first and then I'm going to make the red
7:02green pair my second pair so this is the
7:04corner and this is The Edge now I'm
7:06going to solve this with just Lu moves
7:08into the back here so I know that this
7:10corner will stay here and the edge I
7:14believe is going to end up in the same
7:16place that is right now I'm not quite
7:19sure so I'm going to close my eyes do
7:22this
7:23fair and I think I messed up but let's
7:25say it is where I thought it ended up so
7:27I'm going to do this corner and this
7:29Edge
7:30and yeah I got it wrong but as you can
7:33see that is a good Jewel as is Pretty
7:35challenging even for me so it's a good
7:37way to practice your look Ahad and if
7:39you're able to predict your second pair
7:41that makes it so you're two pairs ahead
7:43on your look Ahad so you have a lot of
7:45time to find your third pair or fourth
7:46pair whatever so the next point is not
7:49utilizing inspection enough the more you
7:51can predict an inspection the easier
7:52look ahead it will get so if you predict
7:55cross you have let's say 7 Seconds to
7:59predict your first pair but if you
8:01predict cross plus one well then you've
8:04already predicted that first pair so you
8:05have another maybe half a second to a
8:07second of time where you can predict
8:09your next pair which would be the second
8:10pair in that case and if you predict
8:12cross plus two well then you have a ton
8:14of time to predict pair free so the more
8:16you inspect the better you're going to
8:17get a look ahead or the easier you'll
8:20make it for yourself to get good look
8:21ahead so how do you go from let's say
8:24being able to predict Three cross pieces
8:26to planning cross plus one so
8:28essentially
8:30you just want to think about where the
8:31pieces you're looking at are going and
8:33this might take you minutes or sometimes
8:36hours let's say you make it the goal to
8:38predict pair one well if you're only
8:41able to predict Three cross pieces you
8:43might need to spend 15 to 20 minutes on
8:45this but if you do that 15 to 20 minutes
8:47like 10 times so you spend hours
8:50practicing it at some point you're going
8:52to get good enough at it that is going
8:53to be automatic and you don't even
8:55really need to think about it so in this
8:56case I can predict two pairs pretty
8:58easily
9:01like that because well I've spent like
9:04thousands of hours practicing that it
9:06just comes naturally to me but trust me
9:08at the start it was very difficult last
9:10year when I was in Ohio for the Great
9:12Lakes Championship I was staying at a
9:14friend's place for uh about a week and
9:17he was at University so he would leave
9:19in the morning and come back in the
9:20evening and for those like 6 to 8 hours
9:22that he was at University I'd just be
9:24sitting at his place going between doing
9:26attempts of predicting full f2l that
9:28would take me like anywhere from 2 to 10
9:31minutes and then doing a few of those
9:33getting really tired taking a few hours
9:35break and then going back to it then
9:37he'd come back home and I'd be like yeah
9:39I predicted f2l once so this is
9:41something that's going to take a lot of
9:42effort and a lot of time and that's
9:44completely normal you won't get it right
9:46at first but it's really rewarding when
9:48you do get it right and you see that the
9:50pieces you planning are solved and it's
9:51also a very tiring drill so don't be
9:54worried if you notice that you get tired
9:55after a few attempts that's normal but
9:58over time that fatigue is going to make
9:59you better so just keep doing it and
10:02don't don't go too hard cuz you might
10:04fry your brain so once you've developed
10:07good look ahead it's also very important
10:09to start looking for edges that are
10:10oriented and a lot of people don't
10:12understand Edge orientation in f2l like
10:14at all so the basic concept is that if
10:17an edge is uh matching the top color
10:20with your front or back Center that
10:22means it's oriented and when it's
10:24oriented it means you can solve that
10:27edge and its whole f2l pair we have just
10:30r l and U moves so it's just nice finger
10:34tricks essentially and if you have the
10:36opposite where the top color of the edge
10:38is matching either the right or the left
10:40side that means You' have to rotate to
10:42use r or L moves to solve it so with
10:46this let's say we have these two pairs
10:49if I just looked ahead to these two
10:51edges and I see this one is oriented and
10:53this one is misoriented well then I can
10:56just choose this pair based off of that
10:58and then that eliminates an extra
11:00rotation because if I were to do this
11:02pair first I would rotate and I have to
11:06rotate back for this pair since I left
11:09it so once you develop a good
11:11understanding of EO you can move on to
11:13pseudo slotting because EO is very
11:15fundamental to doing pseudo sloting and
11:17without it you can't really tell which
11:19pairs are which so for example these two
11:22pairs are exactly the same except in
11:25this case the edge is oriented and in
11:27this case the edge is misoriented if if
11:29you don't see that then you just do this
11:31for both pairs and one would end up with
11:33a misoriented edge and the other would
11:34get
11:35solved so the way youd recognize that in
11:38a solve is this color here on the top is
11:41matching the center and right here top
11:44color is matching the side so that's how
11:46you know this is a flip pair so to solve
11:48it you would split the pieces and then
11:50solve it with a free mover whereas this
11:52one is just a Sol slot so you can answer
11:55it like that the pseudo is a very
11:57difficult concept to understand and get
11:59good that but we go over how to practice
12:01it and how to understand it better in
12:02the course so the last reason is very
12:05fundamental and that is bad technique so
12:07for example bad finger tricks an example
12:10of that specifically would be right here
12:12I want to solve this pair and to do that
12:14I need to do R U2 R Prime but in this
12:19case the only efficient way to do those
12:21three moves is to do a left to U2 and
12:24then R Prime cuz otherwise either you
12:26have to do U Prime U prime or or you
12:29have to regrip your right hand to the
12:30bottom and then the normal you with your
12:32right hand and both of those lose a lot
12:35of time so learning all the basic finger
12:38tricks is very important for fast f2l
12:40and then getting good at those finger
12:42tricks being very very precise with them
12:45and being able to do them quickly and
12:46under pressure is another thing so first
12:49you need to learn all the finger tricks
12:51and be familiar with when to use them so
12:53some finger tricks you have to make sure
12:55that you learn so that you can learn all
12:57the algs that are out there for example
12:59Le s moves there are two types of s
13:01moves there's a regular s move where you
13:03do it like this so the other type of s
13:05move would be like a push move like that
13:08which I can do just on a cube like this
13:10but doing it in an algorithm is very
13:12difficult so just make sure you learn
13:14this with both hands and that unlocks a
13:17lot of algorithms for you like for
13:19example you can do a cross Edge like
13:21this of course besides that you need to
13:23know all of the U2 finger tricks D2
13:26finger tricks and stuff like pinch F
13:28moves you need to to know how to do M
13:30moves with either right or left hand
13:32usually you don't need both although for
13:34some OLS doing M with your left hand is
13:36also useful so if you can learn it with
13:38both hands and then you need to know how
13:40to do double m2s which are only used for
13:43H and Z prims so you just need to learn
13:46M2 with one hand and then you'll do all
13:48your oves with the other and then you
13:51need to be able to do them precisely so
13:53to do that you would essentially do very
13:56slow solves where you focus on each turn
13:59and completing it exactly so that the
14:02magnets align and help you complete the
14:04turn and you're never relying on Corner
14:06cutting because once you start turning
14:08faster you'll naturally start Corner
14:10cutting but if you're using Corner
14:11cutting when you're turning slowly then
14:13you're going to end up relying on it way
14:15too much in your actual solves and
14:17you'll have a lot of lockups it's going
14:19to be very difficult to implement any of
14:21these points if you have the wrong
14:22mindset I believe that you shouldn't
14:25Focus too much on your results you
14:26should focus on improving your Technique
14:28and algorithms at all times so when
14:30you're practicing don't focus on what
14:32times and averages you're getting just
14:34focus on improving a certain aspect of
14:36yourselves and over time your times are
14:38sure to go down so my course is
14:41currently available at cubing Dogg for
14:43$50 off from the full price which will
14:46be the case for next week after this
14:47video is released the course covers
14:49everything from the basics to the most
14:51advanced aspects of cfop so it goes from
14:54not knowing how to solve cross and
14:56teaching you how to get better at Cross
14:57and doing it more efficiently to
14:59intuitive f2l and then all of the best
15:01solutions for all the f2l cases from
15:03every angle to how to do pseudo slotting
15:05and how to get better at it and then it
15:06teaches all of O PL and then teaches all
15:09of the zbl algorithms that I use and how
15:11to recognize the cases the link will be
15:13at the top of the description so if
15:14you're interested check it out so I hope
15:16you learned a lot from this video and
15:18that's all for me today see you
