I just lost a 134 move rapid game on chess.com. My opponent had me by the throat but I soon found he/she wasn’t familiar with how to mate with rook and king v king. 60 moves each occurred without a pawn move or a capture. I expected a draw to be announced after 50 such moves each but that didn’t happen. Should I be surprised or not?
