A very pretty game, my congratulations.

1) 11 ...Bxa3: I made some analyses and it is difficult to know if the
sacrifice is technically correct. I liked this type of move.

2) 30 ...Rc2 is a very strong move and wins with easiness, for this reason it's
difficult to know which the best move.

3) PII-300, HT=64, Fritz5.32
Move     Depth   Time(sec)    Evaluation
 Qc5       9        6           +0.19
 Qc5      13      144           -0.81

Fritz5.32 keep up Qc5 on depths 10, 11 and 12.
Depth 13 ends with Qc5, time=430sec.
