39...Bd7??
better it was 39...Rc6 40.Ce4 or 40.Cxb5
The King could have closed the games before if he played more accurately.
However, MChess has also lost several opportunities to rebalance the game as it has not been able to play more accurately,
not taking advantage of some questionable choices of The King.
