I was playing around trying to find some ways to trap queens that go pawn hunting, especially on b2/b7 or g2/g7. Then after reading the positional? thread I thought of steinitz and run into this gem which I didn't remember.

White's queen grabs three pawns, and suddenly finds itself chased all around the board, giving black a strong attack, with an unsound sac leading to a mate
