After the game, Iryna said that 10.Bd5 was better than 10.Nd5 which was what GM Sergey Kudrin played against her at this year's U.S. Championship.  Even though she lost that game, in her opinion White stood worse after the opening.  Here is the game.  You can judge for yourself.

As for my sacrifice of the b-pawn, it was 100% intuitive.  It seemed to me, over the board, that I could capitalize on Black's loss of tempos in capturing my queen rook.  Especially in game/30, it was a good practical attempt at winning the last-round game.

 

I've never seen 10.Bd5 before.  There are alot of games with 10.Nd5, so 10.Bd5 may be a theoretical novelty.

I wonder if 10...Be7 and 11...O-O is any better and safer.

After 11.Bg5, perhaps still safer and more solid is 11...O-O.

13.O-O is pretty risky, and now is the b pawn a poison pawn as in the Sicilian, Najdorf.   13.Bb3 and 14.Nd5 would be the safe road.

I guess I would like to see analysis on 14...Qxa1.  White then plays 15.Qxf6, then 15...Rg8 16.Bxe6 fxe6 17.Qxe6+ Ne7, then 18...Rg6. 

Brave idea, sacrificing the b-pawn.  How much did you calculate and how much was on instinct?  I really like the idea, but my computer (which has no sense of romance ) suggests 14...Nd4 is an improvement.  See the variation below.

 

That was a very fun game Jim. I'll wait for someone stronger to analyze it.
