Winter Variation -Petrus BDR-BR Block

[rcbeyer]

Well I hope I am tossing this into the correct place.

To be honest I'm writing this more as a place of reference for myself, but I am posting this in the hopes that it can be useful to someone else. . . Here's to hoping - Cheers

For those who do not know what the Winter Variation is here is a short definition: Inserting your last Corner Edge pair in a way which the last layer corners are oriented

F2LL(Winter Variation) kinda caught my eye and I'm a bit interested in learning some, if not all of F2LL.

F2LL Has an interesting effect when solving using the Petrus method, since you orient all the edges after you solve your 2x2x3 block, inserting your last corner edge pair using F2LL gives a forced OLL skip every time, however I ran into a bit of a problem:

I noticed that when I use Petrus that I nearly always leave the BDR-BR corner edge pair for last and the only place that I've found with F2LL algs had the FRD-FR corner edge pair as the last insert.

So here are some algs for F2LL insers using the BDR-BR corner edge pair:

There are a total of 27 F2LL algorithms + mirrors

For F2LL concerning the FRD-FR last slot please refer to this site here

For F2LL concerning the BRD-BR last slot please, read on:

I have no idea who made it but they are my new best friend

Lucas Garron, your alg.garron.us tool is infinitely awesome

Cride5, I your Algorithm Translator, to be honest I didn't find it of much use until I started solving one handed, and then I again used it for this page today, Thanks

Tell me what you guys think, constructive criticism is always appreciated, gotta be constructive though, I don't feel like crying today -.-


Well if anyone made it this far, thanks for reading, I hope that I was able to help someone out.

Its interesting that you insert that last I solve which ever side is easier than I rotate till the slot is in front and the two free faces are U and R or U and L. But one thing about F2LL is that you only want to learn it if you don't care about learn alot more algs because you can just insert the pair like normal and the algs go from 27+mirrors to 7 and no mirrors.

Incredibly true, that is why I said I was interested in some, if not all, because there are some cases that I would find more favorable than inserting + OLL, F2LL uses fewer moves than inserting + OLL as well. What I do depends on the case and the recognition to be honest.
