Apr-11-21  Brenin: <drollere>, <Walter Glattke>: In your lines, after 35 Rxg7 Bxg7 36 Nxg7 Kxg7 37 Rg1+, playing 37 ... Kh8 (instead of Kf8), with Qf6 to follow, seems to give Black a safe escape.

  agb2002: White has a bishop and a knight for the bishop pair.

White can try to resume the attack by weakening the dark squares around the black king with 35.Nxg7 Bxg7 36.Rxg7 Kxg7 37.Nf5+:

A) 37... Kf6 38.Qd4+ Kg5 (38... Kg6 39.Qg7+ Kh5 40.Qg4#) 39.Qg7+ Kf4 40.Qg3#.

B) 37... Kf8 38.Qh6+ Kg8 39.Qg7#.

C) 37... Kg6 38.Qh6#.

D) 37... Kg8 38.Rg1+ Kh8 39.Qd4+

D.1) 39... f6 40.Rg8#.

D.2) 39... Qf6 40.Nh6 wins (40... Qxd4 41.Rg8#; 40... Bd7 41.Nxf7#)

D.3) 39... Nf6 40.Rg8+ Kh7 (40... Kxg8+ 41.Qg1+ and mate in three) 41.Rg7+ Kh8 42.Qg1+ wins.

E) 37... Kh8 38.Rg1 Qf6 and Black holds.

I don't know. I'd probably play 35.Rg3 to prepare the attack to have better chances.

  agb2002: I discarded 36.Nf5 because 36... Bf6 looked to me enough to hold. However, Stockfish gives 37.Qh6 as winning.

  pittpanther: I played Michael Brooks several times in the late 80s and early 90s. He was a strong player, I think ultimately got to IM. He would play in weekend tournaments - and normally won them. I had one interesting ending that went down to R + 2P versus R+1P, i was down a pawn and was shuffling my rook on the first rank which would have drawn. I made a mistake and took his pawn on the 7th rank (seemed like a good idea, since it was only one square from queening) and got a lost position.

  drollere: <Brenin: <drollere>, <Walter Glattke>: In your lines ...>

i think glattke's point was that my line was "too nice to be true."

Apr-11-21  King.Arthur.Brazil: In the beginning I chose 35.♖xg7 ♗xg7 36.♘xg7, however it didn't threat anything to make Black go into 35...♔xg7. So, I change to 35.♘xg7 first, for example, 35...♖b7 36.♘7e6 fxe6 37.♗xe6 where White threates both 38.♗xc8 and 38.♖g8# also continuing the attack. Then, Black must accept the ♘}. After, 35...♗xg7, I followed with 36.♖xg7 ♔xg7 37.♘f5+. Now if, 37...♔f8 38. ♕h6+ ♔g8 39. ♕g7# or 37...♔f6 38. ♕h6+ ♔e5 39. ♕g7+ ♔f4 40. ♕g3# or even ♔h8 or ♔g8 it seemed that with 38.♕h6 the check-mate was near, however, for my delusion, the simple 35...♔h8 36.♕h6 ♕f6! and the combination is refuted. I guess that white had carefully analysed this, when continued with 36.♘f5! which I truely didn't imagine at first. Following the game, if Black tries 36...♕f6 37. ♘xg7 ♕xg7 38. ♖xg7 ♔xg7 39. ♖g1+ ♔h8 40. ♕h6 and check-mate next. Also the line 36...♗f6 37. ♘h6 ♗g7 38. ♖xg7 ♔xg7 39. ♖g1+ ♘g5 40. ♖xg5+ ♔f6 seems game is over. After 39.♖cg1, Black could already resign, since 39...♕f6 40.♖h5 and the threat 40. ♘xf7+ ♗xf7 41. ♖h5+ ♗xh5 42. ♕h6# is unstoppable. Nice game!
Apr-11-21  1g1yy: Well, I got the first few moves so I'm happy about that. I often run into problems where I might get the attacker's move, but fail to predict the defenders move correctly. And this was another example of that. White's moves were fairly obvious; Black's? Not so much.

What would really be a cool functionality for this java app (I assume that's what we're using here) would be to add a "puzzle mode" in which I'm expected to find the one player's moves, and if I do so correctly, IT plays the move of the other player so the puzzle can continue. Basically, find the best moves for the winning side and you get credit for a solve.

As was the case several times this week, the defender's moves were a blunder. I don't play strong enough to find the moves all the time anyway, much less when I think I'm on a correct path and the defending player does things like the above.

Apr-11-21  sp12: How about:
36...Qf6 followed by b3 to block white bishop, and then be8 to bd7 etc?
Apr-11-21  RandomVisitor: 34...Qd8 set up the puzzle. Can black improve with 34...g6 and escape with an even game?

  Breunor: Looking at the puzzle picture, that has to be among the most pieces on the 8th rank on move 35.
Apr-11-21  messachess: This is a doozy of a problem, very nice.
Apr-11-21  RandomVisitor: Earlier black had 30...d5 or 30...Nh7 for advantage:
