One Handed Solving
Have you ever wanted to try out One Handed solving with the ZZ Method? WELL, YOU'RE IN LUCK!
Which hand to use for One Handed Solving?
You have to decide which hand to use for OH solving, the left hand provides a great grip for doing <RU> moves, while the right hand has more access to <LU> moves. Experiment with what hand you are more comfortable to solve with. After you have decided, it is time to learn some finger tricks. Good finger tricks are very important in OH, as without them your OH solving will be very sloppy and slow. It is also advisable to use R moves (left hand) or L moves (right hand) with your pinky as it gives more room for turning.
A great resource for finger tricks is a video from Phil Yu, as shown below.
Text Version (Left Hand / Right Hand - Fingertrick)
R/L' - Put Pinky in BDR or BDL corner and push up
R'/L - Put Pinky in FDR or FDL corner and push down
R2/L2 - Either double flick or do RR/L'L' or R'R'/LL
U' - Put Index Finger in BUL corner and push to right
U - Either put Index Finger in LUB corner and push to right or put IF to FUL corner and push to right
U2 - Either put Index finger in LUB corner and push to right or do UU/ U'U'
F' - Put thumb in center and push counterclockwise
F- Put thumb in center and push clockwise
D and D' - Put ring finger in LDB corner and push right or left
B and B' - Do like Fw/Fw' and rotate z/z' depending on move
EOCross or EOLine?
EOLine is recommended for OH solving. While it has worse look ahead, TPS, and ergonomics for 2H, it actually works quite well for OH. In OH, since TPS is somewhat limited, look ahead is much easier. Ergonomics also aren't an issue for EOLine in OH, since regrips for R/L aren't present in OH finger tricks like they are in 2H.
EOCross is a few more moves than EOLine, and F2L is less efficient than blocks. One of the benefits of EOCross in 2H is easier look ahead. But, since look ahead isn't much of an issue in OH, the extra moves you have to do aren't worth it most of the time. So if you see an easy EOCross, go ahead an do it, but EOLine will be better most of the time.
Last Layer and Algs
For OH you can find different versions of algsets that will be better suited to the more limited fingertricks you will have. Some people learn the two different versions but most will learn the algs for whichever event they are going to practice and focus more on. Many OH specific algorithms can be found at AlgDb, labeled as OH, then the set's name.
There are a few alg sets used for OH. Here are some of the more well known/explored sets:
- COLL/EPLL: While not being much of an upgrade in 2H solving, COLL/EPLL is a huge step up from OCLL/PLL in OH. Given the speed that 2-Gen algs can be executed in OH, having a slightly worse OLL with a 2-Gen PLL is definitely worth it.
- OH ZBLL: This isn't too different from normal ZBLL. The only things that change are alg ergonomics and move count. While you can use normal 2H ZBLLs for OH, the ergonomics are normally worse for OH solving. So, if you're serious enough (or crazy enough, like a few of us) about OH to learn OH ZBLL, it will be worth it.
- CPLS/2GLL: This is the least used set on this list. The main reason why it's not used by too many is recognition. The CPLS recognition isn't too bad, but it can be odd to get used to. So if you want a great LL for OH, but don't want to learn full ZBLL, CPLS/2GLL may be for you.* As long as you care to get used to recognition, of course.
