Yeah you are totally right.
Tactical Game leads to draw.

Thats rook queen shuffle is what I didnt understand. You both played well and saw things that I did not, but I'm wondering why you didnt ignore the queen movement and set up and attack with your rook and queen. Your king was more then protected on that side of the board
just my 2cents

That last sac is hard to take.
You were ahead a pawn, with more active pieces. Trading favors you... you say you didn't come that far to trade queens, but you ended up coming that far to force yourself into a draw with a bad sac, how is that better? You could have traded queens and fought on... I think you had much the better game.
If you were hell bent on the risky play, you could also have kept your Queen and tried Qc7!? with the idea of wreaking some havoc on his queenside pawns -- (although Qc7 would seem to threaten Qxa7, I don't actually think you want to win that pawn... far preferable I think would be winning the b or c pawn!) Just make sure you can defend your h-file, and watch out for him eventually sacing his bishop on your h pawn if you push h3.
This was a great game as it seems like forever since I've played a game with any tactical chances. I know the bishop move was dubious, but I thought my opponent might try to save his queen and in doing so would give me a forced mate.
Check it out. Would love your comments. And to my opponent...Great Game!!
