Thanks Greg,
I just wanted to make sure I understood the defintion of mirror symmetry.
I definitely think multiple moves per turn is something to continue exploring (not necessarily in chess engines, but in the games).

I've thought about adding the feature to Trappist-1 (version of Chess on an Infinite Plane). It will help correspondence games go faster when only one move is played per day. Of course it also changes the strategy. The opening and mid-game will go-by faster, and then the final "clash" can be much more damaging.
Theres are some game notations on this site with double-moves, but all are very short (like 10-15 moves). But with a large format game I think it can work really well, and with Cataclysm, using it for selective pieces (just pawns) is a great idea.:)
