A serious alternative is 13. ..Kf1, which has the advantage of keeping open the d1-h5 diagonal, thus robbing Black of his counterplay based on 16. ..Nh5. 13...Db4

However White does not need to take any risk. He can try to improve his position slowly and systematically.] 17...Sf4

Black's knights look very active, but they risk also to be driven away. In this case Black must be ready to have sufficient counterplay elsewhere on the board. I would have liked to play 19. ..a4, but unfortunately it does not work.So I was forced to choose the only other active possibility. The text move occasionnally threatens ..g5-g4, even at the cost of a pawn. 20.g3

Black needs already complicated manoeuvres, just in order to complete his development. Square f8 is evacuated for the knight, who prepares the development ..Bc8-d7. I think this is the right decision. [ 21...g4?

This is already necessary, since Black was threatening to play himself .. g5-g4. Both sides have now mutual weaknesses : Black's Bg7 is locked up and his Ph6 is weak, whereas White's Pf3 is weak and there are problems to get the Ng1 in an active position. I think that the position is almost balanced. 27...Da6

Probably White has nothing better. But after this move I was confident that I would obtain the draw which I was aiming at for many moves. The combination starting with 35. ..h5!! has already been prepared at this stage. 34...Sh4

Black is ready to sacrifice a pawn and an exchange, in order to force a draw.Initially I had planned 35. ..Qf7, then 38. ..Qg6 and then only 39...h5. But that appears to be rather slow. White can react in several ways, and I found no forced result. 36.Lxg5

White must now play 42. Kg3, since 42. Kg2 Qh2+ would lead to mate. After 42. Kg3 Black can give perpetual check in various ways. A truly interesting and exciting game. I would like to know if there exist any strong Chess playing programmes, running on the quickest computers, who can find the combination starting with 35. .. h5!! as well as the consequences of this. I mean: can such a programme " see " already at move 34 from White that Black has now a forced draw?! 1/2-1/2
