This game is very similar to chess, except that you have to ask your opponent to make a move, if he accept , you have to play the move, if he refuse you can play an other move of your choice. Remark : If only 1 move is possible , play it without asking.
Example :
player1 : "can I play e4 ?"
Player2 : "no"
Player1 play d4 (for example)
player2 : "can I play Nf6"
Player1 : "yes"
Player2 play Nf6
...
There is very amazing side effects : you can take piece who are defended only 1 time because you can refuse the opponent take your piece.
It's impossible to mate in KRK because you can always refuse the last mating move
Is there an engine who play this ???
Thanks !
