Underpromotions and early promotions

There are threads about early checkmates (10 or fewer moves, 20 or fewer moves). But here is something more rare: Do you have any games with early pawn promotions (say, about move 15 or earlier), or "legitimate" underpromotions? By legitimate, I mean that they actually served some purpose, even if they weren't the best move, but some purpose other than "just for the heck of it."

I was in a rated tournament once, and I promoted a pawn on move six (my first move was a knight move, the rest were pawns...) and my opponent couldn't recapture immediately. We had to bring a TD over, and he stopped our clocks until another board had a captured black pawn we could use.

Nice examples, especially the N promotion, which was not for a checkmate or a fork, which are the "normal" reasons you see. Keep 'em coming!

Not on here, but in a blitz game I once had someone play right into the (not so?) well known Albin Counter-Gambit Lasker trap: 1. d4 d5 2. c4 e5 3. cxd5 exd4 4. e3 Bb4+ 5. Bd2 dxe3! 6. Bxb4? exf2+ 7. Ke2 fxg1=N+!
