Hi guys, I got home yesterday from my trip to China & Malaysia, and I've already had a couple of requests for commentary and reconstructions from my 5.80 official 3x3 average! :) Work on more video tutorials, blogs & resources for CubeSkills has "officially" resumed.
I got this average in the first round of the Malaysia Cube Open 2017, I was pretty surprised with the times I was able to post at around 9am in the morning. Big thanks to Stewy for doing reconstructions so quickly for everyone!
Scramble 1: B U' B' F' U' R2 U' L B2 L' D2 B R U' R2 B2 F2 U'
This scramble was nothing special, there weren't any crosses that were particularly easy. I did the extended cross with the red-yellow edge and the blue-yellow-red corner because I was unable to easily plan any of the other blue F2L pairs. It ended up being 14 moves, which is far from ideal, but the fingertricks were okay and it was rotationless.
Inspection: x y
3 cross edges and first pair setup: D L D U' R (U' D)
Finish X-Cross: L' U' L U2 L F' L'
Luckily, the next pair was easily visible after the X-Cross and didn't require any rotations.
2nd pair: U' R U R' U R U' R'
The third pair was also reasonably easy to see whilst executing the solution for the second pair.
3rd pair: y R' U' R U' R' U R
I paused slightly before the final pair because it was a super easy OLS case, and I just wanted to double check my recognition. I literally uploaded a random video showing this easy-to-recognise case on the CubeSkills YouTube channel earlier this year, it's quite a fun one to execute.
OLS (Orientation of the Last Slot): R U' R' U R U2' R2' F R F'
PLL was then just a T permutation :)
PLL: U' R U R' U' R' F R2 U' R' U' R U R' F'
5.99 seconds, 54 moves (STM), 9.02 TPS
Scramble 2: B U' L' U R2 B D R' D2 B2 R2 F2 U' B2 L2 D2 R2
During inspection, I saw that both the red-yellow-green and red-blue-yellow corners were correctly attached to their cross pieces, so I wanted to build an X-Cross in some fashion. Unfortunately, the red-yellow cross piece wasn't in a great position, and I was running out of inspection time, so my solution for the X-cross was a little bit ugly. A nicer alternative X-cross on yellow would have been L R' F' R2 D' R2' D', which leads to some really nice continuations. A nice double X-Cross on red which preserves both attached corners would be z D' L2 F2 L' u R' (R' U' R) (L U2 L') D2, but I really doubt I'd have seen that in inspection in a competition setting.
Inspection: x2 y
X-Cross: r' u' R l U2 l' y' R' U' R u'
Recognition of the second pair was a little bit tricky, because the green-white F2L edge was at the back of the cube. The lookahead & regrip here cost me a bit of time.
2nd pair: y' U2' R' U2 R U' R' U R
The third pair made use of the open front F2L slot.
3rd pair: U R U' R' L U2 L'
The last F2L pair was pretty standard, and cancelled into the 6 move OLL. After doing U' R U' R' U2, it's fairly straightforward to see that doing R U' R' will preserve the orientation of the back-right corner, as well as orient the 2x2 block in the back left, and so from that we can determine that we'll get a P shape OLL, and so I cancelled the last pair into OLL.
4th pair: U' R U' R' U2 R U' R2'
OLL: U' F' U F R
5.28 seconds, 39 moves (STM), 7.39 TPS
Scramble 3: L2 B' R B2 D' R B' F2 L R B' R' F R2 U2 R2
Another red cross, but this time it was 2-generator (R and D), which made it really easy to execute, and also meant that the blue-yellow F2L pair in the top-left position didn't move, and so it was easy to see the first pair. I was also really confident (but not certain) that the blue/white F2L pair would end up as a 3 move insert after I solved the first F2L pair. This meant that the cross and first 2 pairs in this solve were super quick.
Inspection: z y
Cross: D' R D' R D2
1st pair: U' R U' R' U R' U' R
2nd pair: y' R' U R
It's always a bit tricky to try and lookahead after planning this much in inspection. I was also concentrating to double check that the 2nd pair would present itself as I anticipated in inspection, so I wasn't really trying to look for the third pair. However, I did know that life would be made a little bit easier by the fact that the 2 solved pairs would end up in the back two F2L slots. Luckily enough, the 3rd pair was just an easy 3-mover (after setup), and whilst inserting the third pair, the 4th pair pops out of the FR F2L slot, ready to be solved and inserted into the final slot.
3rd pair: U2' R U R'
4th pair: y' U' R U' R' U R U R'
This OLL really sucks to execute under pressure. The F2L was finished in just over 3 seconds, but I got quite nervous & panicked whilst executing the OLL, which caused some lockups. It could have quite easily been a sub 5 solve with just slightly better execution.
OLL: L F' L' U' L U F U' L'
5.25 seconds, 38 moves (STM), 7.24 TPS
Scramble 4: R F2 R' U B2 L' B L' B' L U' F2 U' R' U2 F R U2
I panicked a lot in inspection here, so much so that I didn't correctly plan the first pair, and ended up solving it very inefficiently.
Cross: D R D F L F D
1st pair: U' F' U' F R U' R' U' R U R'
Luckily, my stupidity ended here and the rest of the solve was really smooth. I solved the next pair with two rotations, but it worked out nicely as the 2 solved pairs ended up in the back, and the final two pairs didn't require any rotations as the edges were oriented.
2nd pair: y R U' R' y R' U' R
3rd pair: U' L' U2 L U' L' U L
4th pair: U' R U' R' U2 R U' R'
Once I got to OLL, I noticed that the UFL corner and UF edge pieces were a correctly-connected block, and I also know that the standard OLL algorithm for this case preserves this block, as well as attaches the UBL corner to it. Based on this, I could tell that there would be a 1x3 white block for PLL, and I also knew that it would end up on the left hand side (just based on experience and knowing what the OLL algorithm does). Therefore, I'd have either a J permutation or an F permutation as my PLL, so there was almost no pause between the OLL and J perm on this solve.
OLL: U2 R' U' F U R U' R' F' R
PLL: R U R' F' R U R' U' R' F R2 U' R'
6.13 seconds, 63 moves (STM), 10.28 TPS
Scramble 5: F' L2 U2 F' U2 F2 L2 F2 R2 D2 F D L R2 D2 B R2 B2 U2 R
Yeah, I messed up the execution on this last solve, and so by the time I got to PLL I knew it was going to be the worst time anyway, so I kinda gave up on it. The X-cross was far too convoluted, but the actual solution for the remainder of the solve was okay.
Inspection: x' z2
X-Cross: (U' D') R' F (U D') R' (D U') L' U L D
2nd pair: U' y' U R U2' R' L U' L'
3rd pair: U y' R U' R' U R U R'
4th pair: y R U2 R' U R U' R'
OLL: U' r U2 R' U' R U' r'
PLL: D' R U R' U' D R2 U' R U' R' U R' U R2 U
9.19 seconds, 60 moves (STM), 6.53 TPS
