Mar-11-23		Brenin: I saw 31 ... Bh4, and the follow-up as far as 36 Kd3, and I wasn't convinced that Black had enough compensation for the sacrificed B, e.g. after 36 ... Qf2 wouldn't 37 Qc2 have been a better response than Rc2? OTB I would have been more cautious with 31 ... Qh8 and 32 ... Rh1.

Mar-11-23		jrredfield: I was debating between 31 ... Bh4, 31 ... Qe8 and 31 ... Rh2+. I chose Bh4 because it would lead to a major Black attack on the h-file, putting White on defense. This doesn't appear to give Black a big advantage all at once. With 32 Ne2 Qe8 33 Rg2 Bb5, Black is closing in from two directions. With 31 ... Qe8 32 Qd3 Bd6 33 Rc2, I don't see as clear a coordinated attack by Black. But either way, there is no quick significant gain for Black - many hard-fought moves remain.

Mar-11-23		King.Arthur.Brazil: Firstly, I tried 31...Rxb3 32. Rxb3 but Bh5 blocked the own attack while Rh2+ seems to simplify the material,which could be good for White. I realized that the ♗ is in a wrong place right now. So, I preferred to sacrifice it with 31...Bh4. But if White take it? The line: 32. gxh4 Qxh4+ 33. Ke2 Rh2+ 34. Kd1 Qf2 35. Qd3 Qxg1 seems good. Then, Black will chose 33. Kf1 which lead to Rh2 34. Rc2 g3 35. Ng2 Rh1 36. Ke2 Qg4+ 37. Kd2 Qf3... many possibilities. For 34. Rc2 g3 35. Rcg2 Qg4 36. Qd1 Bb5+. But I really don't see good fortune for 32. Ne2 Bxg3+ 33. Nxg3 Qh4 34. Rg2. The King is not so good, as he thought he was in the past. Grey times. Time to see what has happened.

Mar-11-23		King.Arthur.Brazil: I didn't saw 34...Qg3!. Liquidation is fastest way: 42. Qc1 Bxc2 43. Qxc2 Qxc2+ 44. Kxc2 g3 45. Kd2 g2 46. Ke2 g1=Q end.

Mar-11-23		devere: After 31...Bh4 32.Ne2 Bf6 Nc3 Black has a very nice advantage, but it's hard for me to see he is winning.

Mar-11-23		mel gibson: I saw the first ply in about 30 seconds - White should not take that "free" Bishop. Stockfish 15 doesn't take it and mounts a better defence: 31. .. Bh4 (31. .. Bh4 (Be7-h4 Nc3-e2 Qd8-e7 Qb1-b3 Bh4-f6 a3-a4 Qe7-e8 b4-b5 a6xb5 a4xb5 Bc6xb5 Rc1-c7+ Kg7-f8 Qb3-a3+ Kf8-g8 Rc7xh7 Rh3xh7 Ne2-c3 Bb5-c4 Ne1-g2 Bf6-e7 Qa3-a5 b7-b5 Rg1-a1 Qe8-c6 Nc3-b1 Rh7-h1 Nb1-d2 Rh1xa1 Qa5xa1 b5-b4 Qa1-a7 Be7-d6 e3-e4 d5xe4 Nd2xc4 Qc6xc4 Ng2-e3 Qc4-d3 Qa7-b6 Qd3-d2+ Kf2-f1 Qd2xe3 Qb6xd6 Qe3-d3+ Kf1-g1 Qd3xg3+ Kg1-h1 Qg3-e1+ Kh1-g2 Qe1-e2+ Kg2-g1 Qe2-d1+ Kg1-g2) +3.51/40 241) Score for Black +3.51 depth 40. If I force Stockfish to take the Bishop: 31. Ne1 Bh4 32. gxh4 Qxh4+ (32. .. Qxh4+ (Qd8xh4+ Kf2-e2 Rh3-h2+ Rg1-g2 Qh4-g3 Rg2xh2 Rh7xh2+ Ke2-d1 Rh2-h1 Kd1-c2 Qg3xe3 Kc2-b2 Rh1-h3 Qb1-c2 Qe3xd4 Qc2-e2 Kg7-f7 Qe2-d1 Qd4xf4 Ne1-c2 Qf4-c4 Qd1-d4 Qc4xd4 Nc2xd4 Kf7-f6 Rc1-e1 f5-f4 Re1-e6+ Kf6-f7 Re6-e1 g4-g3 Re1-g1 Rh3-h2+ Kb2-b3 Rh2-d2 Nd4-f3 Rd2-f2 Nf3-e5+ Kf7-g7 Ne5-d3 Rf2-f3 Nd3xf4 Rf3xf4 Rg1xg3 d5-d4 b4-b5 Bc6xb5 Nc3-d5 Rf4-e4 Kb3-c2 d4-d3+ Kc2-d1 Re4-h4 Nd5-c3 Rh4-h1+ Kd1-d2 Rh1-h2+ Kd2-e3 d3-d2 Rg3-g1 Bb5-c6 Rg1-d1 g6-g5 Nc3-b1 Rh2-h3+ Ke3-d4 Rh3-f3 Nb1xd2 Rf3xa3) +7.04/41 612) score for Black +7.04 depth 41. And when White resigns: 41. Nc2 Bd3 42.

Mar-11-23		An Englishman: Good Evening: Saw the key move, but 32.Ne2 would have offered better resistance. Perhaps White feared allowing ...Bb5, which is understandable, given that the move eventually won the game.

Mar-11-23		agb2002: Black has the bishop pair for the knight pair. White seems to be preparing b5. The first idea that comes to mind is 31... Bh4 but after 32.Ne2 (32.gxh4 Qxh4+ 33.Ke2 Rh2+ 34.Rg2 Qg3 and Black's heavy pieces will invade White's field) I don't see how to make progress. For example, 32... Bb5 33.gxh4 Qxh4+ 34.Ng3. Or 33... Bxe2 34.Kxe2 and White emerges a piece up. I'd probably try 31... Bh4 to test my opponent's greediness.

Mar-11-23		Allderdice83: <Brenin: I saw 31 ... Bh4, and the follow-up as far as 36 Kd3, and I wasn't convinced that Black had enough compensation for the sacrificed B, e.g. after 36 ... Qf2 wouldn't 37 Qc2 have been a better response than Rc2?> Black's still winning after 37. Qc2, I think. One possible line is 37 ... Qf1+ 38. Ne2 Bb5+ 39. Kc3 Rxe2 40. Qd1 Rxe3+ 41. Kb2 Re2+ 42. Kb1 Qf2 43. Nc2 Ba4, and Black will trade down and easily win the endgame two pawns up with a protected passed pawn. It doesn't matter if White inserts 43. Rc7+ Kf6.

Mar-11-23		OhioChessFan: Being a puzzle position made Bh4 a lot easier to try than it would be OTB. White resigned as his position was hopeless to stop the g Pawn.

Mar-11-23		chrisowen: I quick its won lug puddy match its z juvenile Bh4 ha its abbot blav aha ram its a good quid coin Bh4 and :)

Mar-11-23		outplayer: I have a bias. I have a vicious thought to sacrifice everything no matter what is. In this game I have learned that it is better to sacrifice a bishop than a rook. I thought of 31...Rg3 followed by Bh4+. It has teached a lot.
