been OK for black, as white's pawns and bishop are weak and present problems
for him to figure out. My opponent actually said that he likely would have lost

Nb5. He was psychologically lost and not thinking clearly on moves 28 and 29,
since he was very surprised after my replies Bc8 and Be6, respectively.
Allowing Be6 is not good for white, and taking on e6 is far worse. The rest of
