32. Rxd7+ works well. After 32. ... Rxd7 there's 33.  Qc4+ and depending by Black moves, other checks (taking pawns eventually) or g4/h4 to free the white king from the first rank checkmate.

Very sharp game. Congrats on the win.

Rxd7 wins nothing as the rook recapture threatens mate, or to win the queen again.

After 32. Rxd7 Rxd7, Black forks the queen and the checkmate square d1.  The queen has no safe way of escaping and defending the square in one move, so White has to trade queen and rook, and is then only up a pawn in a tough endgame.  32. Qc4+ was a great finish.

Very pretty game. It must have been fun to play. I don't know much about this line, so I may be wildly off base, but is 14...Rxf5 really Black's best try? What about 14...Bf6? It seems to hold up even after 15.Nb6, Bb7 16. Nxa8, Bxa8 17.Nd4 I can't see much more than a tiny edge for White. Also, is 10...b4 really Black's best move?

Up a clean rook is much easier to win than Queen vs Rook ...

i agree with mimchi

Mimchi, I think it was so force a queen trade and make easy work of a possible endgame. After 32...Qc6 33.Qxc6 Kxc6 34. Rxd8, it's a rook and bishop vs. knight endgame. If 32.Rxd7 Rxd7, the queen will probably go to c4 anyway, only now black has a rook to defend with. The queen and bishop have the odds to be sure, but when playing against a stronger player, you want your chances to be as good as possible.

My favorite part of this game is the genius 19.Rb6!!, where White gives back the exchange in return for both increased pressure over d5 and an attack on the rook. Really nice work!

Why you play Qc4+ at the end? Not Rxd7? winning the Queen?

Nice game though!! Good effect that Bishop had on B3!! Powerful!!
