James, I made some analyses:
1. I think 12. O-O-O is better than 12. a3. I have
"Small Encyclopaedia of Chess Openings", but I didn't
found this variation, I believe that in the complete
"E" book of openings you can found this variation.
2. It seemed to me that 17. h4, don't improve the white game.
3. 18. Qxa8 it's not a good move, black win after this.
I think that 18. bxc3 is better, altought I find that black
continues better. 18. Qxa8 Qc7 19. e3 Rg8!,
instead 19...Nb1? is the good move.
4.I don't get to see how can white win after 28. Qg7.
May be you can improve this analyses.
