Tactic Spotted

I don't know if it was the best move, but it made all the difference in the game.

What I was impressed with was the potential mate in 7 (the key word being "potential" because it was not forced.) The fact that I saw it was what suprised me a little. Normally I would not have considered the move, but I kept going down the line to see where it would lead. My opponent saw the danger of being greedy and did not take the bait.

Anyway, here's the position:


He had just moved f5 threatening to capture my queen when I moved Ng6. If 21. ... fxe4, then 22. Nxe7+ Kh7 23. Rxf8 Qc7 24. Bxe4+ g6 25. Bxg6+ Kg7 26. Rf7+ Kh8 27. Rh7#

But my opponent failed to move his rook at f8 and I captured it with my knight and I went on to win.
