The EKA method is an intermediate step between something such as M2/OP to full 3 style. It works on the basis that you can set up to a specific helper piece, do a commutator to solve 2 pieces, and undo the set up.

All the comms use comm notation, which is in the form of [A:[X, Y]]. This would be read as A, X, Y, X', Y', A', with A being a conjugate.

Before you jump straight into this, it is important that you understand how comms work.

The purpose of this method is to allow 2 pieces to be solved at once, while keeping case count low. The whole method requires 40 comms/algs for a 3 style solve, and almost all of them are intuitive.

It can be coupled with something like orozco to increase chances of solving without set up, and can also be used as a fallback when you're not certain about the comm or you don't know it when using 3 style.

Cycle breaks- exactly the same way as in any other bld method. Shoot to an unsolved piece and take it from there.

Twisted corners- set up to 2 sunes to twist 2 adjacent corners, or place both corners on U, repeat R' D' R D to twist UFR, do a U*, then repeat for the other corner(s).

Flipped edges- without parity, same way as in M2 or OP, or set up to an edge flip algorithm. With parity and only one flipped edge, flip it with UR not UF. See example solve with parity.
