DarwinKoala: At first I thought that enforcing the Ice Age before evaluating the position would be too big an advantage for White because he can mate on move 20, 40, 60 in a conventional way but Black cannot. But maybe this evens out a bit that Black has a serious advantage in always having the last move before the Ice Age.
(ocultar) Si deseas jugar una partida contra un adversario de nivel similar, puedes definir en tu invitación de nueva partida un rango BKR apropiado a tu interés. En tal caso, nadie con un BKR fuera de dicho rango podrá ver o aceptar la invitación. (Katechka) (mostrar todos los consejos)
