-Ambiguous chess
-https://www.chessvariants.com/mvopponent.dir/ambiguous-chess.html
-Need special highlight square --> similar to enlightened for Dark, in Board.vue
-Also in notation, show only dest square for "opponents ambiguous moves".
-Similar to Marseille-chess, white first move only 1 subTurn, do not choose a square.
-Then black has a free first move, then choose a square, and the process goes on.
-
-(Note: could simplify Marseille FEN, just indicate turn)
