Unachess is a chess variant played with a standard board and pieces. It starts with each player having all his pieces in hand. The players start by putting their pieces on the board.
Also, please add crasyhouse. In both variants, the reserve may reclace the material difference line.
See
lichess.org/forum/lichess-feedback/bughouse-2#5Much of that post applies to the case of Unachess. Sorry :(
But ICC has crasyhouse. Why we can`t?
Unachess sounds fascinating to me. Never heard about it before, either ...
