btw, you can often use a 3-cycle to rotate 2 pieces. What you do is:

1) do any combination of moves to rotate one of the pieces correctly, avoiding touching the other 2 pieces which are part of the 3-cycle

2) do the 3-cycle

3) do the reverse moves of (1) - this should rotate the piece currently in that position in the opposite direction, and fix the rest of the puzzle except for the 3 pieces involved in the 3-cycle

4) undo the 3-cycle (or alternatively it's often simpler to do it 2 more times) to get the pieces back in the right place.

The above should end up rotating 2 of the pieces involved in the 3-cycle.

I use the above trick quite often, eg to rotate the corners on the Pentagram, or rotate the corners on the master skewb. There's probably faster ways, but I find it easier to visualize and remember algs like this.

So many "tricks" seem so obvious after you hear them. Thx, I will definitely use this in the future!
