It is a good move, but I don't think it is as strong as what I played. At move 17 I think white should be lost. The exposed king and weak d pawn, and blacks two bishops give black enough advantages that I think (s)he should win. And I think 17....Qd5 is the most positionally justified approach. > >For white I think that 18. a3!? Be7 19. Ne3 >it seems to be better than 18. Qa4?! Black's bishop will be going to e7 and f6 eventually anyway, to presure the d-pawn, so 18.a3 is not a big upset to black. On the plus side, it does help white with what to do about the problem k-rook, which would like to go to e1. The immediate 18.Ne3 may be better. In any case, I think black has a winning position against any of whites possible 18th moves. > >Paulo Soares, from Brazil Robin Smith
