TL Chess match II - Page 44

But I was thinking of Nd1 and then bringing our rook back to attack black's past pawn. I'm sure there is some way to refute this but I can't think of any right now.....hmm....maybe g4 followed by h3 refutes it.

The main idea is to stop g4 by gobbling up some pawns, as after 36...g4 37.Kxh4 g3+ 38.Kxg3 Rf3+ 39.Kg2 Rxa3 40.Re7+ Kg6 41. Rc7 white is winning

Better for black is Rf3, but here we still manage to get a small advantage - 36...Rf3+ 37.Kg4 Rf5+ 38.Kh5 39. Kxh4 Rxa3 39.Kxg5 Raf3 40.Rg6+ Kf8. 41.Nd2 Rf5+ 42.Kxh4 Wins all the black kingside pawns

a lot of lines converge to perpetual check.

dozko I don't get your Rf3+ line. Seems to have some errors in it, including 37. ... Rf5+ (should be R8f4+?) and the lack of a move for black at 38, along with two moves for 39.

I'm going to assume you mean 36. ... Rf3+ 37. Kg4 R8f4+ 38. Kh5, not allowing 38. Kxg5 Rf5+ 38. ... Rxa3 39. Kxg5 Raf3 40. Rg6+ Kf7, not 40. ... Kf8, which loses a pawn. 41. Nd6+ which does 3 things. 1) checks black, preventing him from attacking. 2) guards the critical f5 square and prevents Rf5+. 3) prepares b5 (its about time). 41. ... Kf8 allows 42. b5, and black loses. So the more sensible try, 41. ... Ke7 stops b5, as now the king is closer to the action. But white simply plays 42. Nc4, protecting b4 and attacking the pawn on c5. Black cannot defend the pawn with the king, which loses to Ne5+, forking the rook and king. Black is bound to lose a pawn here, as the only way to save the c6 pawn is to drop the h4 pawn.

I think the more accurate try from black is what I posted in my previous analysis, and black can play on without the loss of a pawn. Still, I don't think we should offer a draw just yet. We still have some play left in here, and we're not down by any means.

36. Nxg5?? Rg4+ and white loses the knight.

I think this is the line you're suggesting...

36. Nxg5 Rg4+
37. Kh3  Rxg5
38. Kxh4 Rg1

Rook is "forced" to move, but it's to somewhere quite good for black. I'm going to be lazy and not look any further, but in the least black can exchange the f pawn for the white bishop.

edit: also mating threat at ..Rh8 since the other rook is on the g file, the king is on the h file, and those pawns would be gone.

You are correct I did botch up that variation ignore that /facepalm

However in your variation after 38...Rxa3, I believe 39. Kxg5 is inferior to 39.Rg6+ Kf7 40. Nxg5+ Ke7 41. Rxc6 winning the pawns straight away, unless im missing something...
