Very nice!!!
Mate in four
Sort:
Very nice sac. I did not see that at first. After I did though it is obvious. It pulls white away from his only escape. Quicker mate.
This is position from one of my games. I had a feeling there is forced way to win quickly and after a lot of calculating I have found the way.
(after first move white has one other option, but black can mate in same number of moves anyway, although with many different variations, depending on white's replies)
