i have been wondering about this for a while. when i try to get the
lowest number of moves for a solve, i count (for example) U2 as 2
moves. according to official rules and in competitions, does U2 count
as 2 separate turns or 1 since it is 2 turns on the same face?
probably obvious, ust didnt know.

thanks

Depends on the metric. There are the quarter turn metric (QTM) counting
only qouarter turns and there a U2 are two turns.

But in half turn metric (HTM) there it is only one turn.

There is also a slice turn metric (STM) and also a quarter for that
(SQTM), both counting slice turns a one turn. Those are otherwise two
turns M = R + L'

Any double turn is counted as 2, so yes, I2 is two turns. M,S,E -slice
moves- are counted as two turns. Anti slice moves are counted as two
turns. (Ra, Ua, Fa). Anything else is counted as 1 turn. Hope that helps.
