What do you do to beat the Antonio Bot
I have defeated Antonio few times. I have taken as much as pawns of Antonio, losing other pieces by taking the opponent's equivalent pieces (trading off) and at one stage Antonio was left without any pieces and I had one or two extra pawns. I managed to move those pawns to the other end and regained the Queen and managed to win.
Простите, что на русском. Антонио я побеждала пять месяцев. Он сводит всю партию к ладьям и пешкам. Любит меняться фигурами
I was able to beat all of the others so far without clues or assistance, this one really seems to be giving me issues.
