|

 | | Phony Benoni: Rather surprising there's not a mate in there some, and we have to settle for the exchange with 32...Qxg1+ 33.Kxg1 Ne2+, trusting the rooks will clean up afterward. |
|
May-25-20 | | stacase: <Phony Benoni ...trusting the rooks will clean up afterward.> And as one of those little sayings when you post says, the most difficult game to win is the "won" game. |
|
May-25-20 | | Cheapo by the Dozen: The trick is to resist all temptations on g2.
And per the engine, White was not premature in resigning, although I'll admit it's not wholly obvious to me why. |
|
May-25-20 | | Cheapo by the Dozen: But then, I'm the guy who, at age 11, managed to lose three "won" endgames at the same American Open. |
|
May-25-20 | | agb2002: Black has a knight for a bishop.
White threatens Rxd4 and Qxf4.
Black has a won ending after 32... Qxg1+ 33.Kxg1 Ne2+ 34.Kf(h)2 Nxg3 35.Kxg3 Rxg2+ 36.Kf4 Rb2. |

 | | scormus: Monday, so it must be 32.... Qxg1+. |
|
May-25-20 | | saturn2: 32..Qxg1+ 33. Kxg1 Ne2+ 34. Kh2 Nxg3 35. Kxg3 wins pawn and exchange. Black can later on exchange rooks by
35...Rxg2+ 36. Kf4 Rh2 37. Kg4 Rcg2+ 38. Kf4 Rxh-

May-25-20 | | Brenin: I spent a minute or three, looking for a mate, before deciding that the game line was the best, and was sufficient for a win. White was already in some trouble, but the pawn grab 26 Bxb7 was negligent: a defensive move, such as f4 or Qe1, was needed. Later, 32 Rb4 was fatal: 32 Be4 Ne2 35 Qb8+ Kg7 36 h5 would have allowed White some counterchances. |

 | | OhioChessFan: A mere 15 years to the week later, <Whitehat's> idea was implemented. |
|
May-25-20 | | AlicesKnight: Looked at g2 and then saw g1 was the answer, as per game. |
|

 | | chrisowen: Mage lecture tributary g1 no? |
|
May-25-20 | | zb2cr: Black gets a winning edge in material with 32. ... Qxg1+; 33. Kxg1, Ne2+; 34. Kh2, Nxg3; 35. Kxg3, Rxg2+ and Black is up by the exchange and a Pawn. |
|
May-25-20 | | mel gibson: That was easy but could it be converted into a win?
After all it's 2 black Rooks versus a Rook & a Bishop. Stockfish 11 says yes:

 | | chrisowen: Runnings now yes ladder no wolf? |
|
May-25-20 | | TheaN: The solution is the rather straightforward <32....Qxg1+ 33.Kxg1 Ne2+ -+>, but extra points for <34.Kh2 Nxg3 35.Kxg3 Rxg2 36.Kf4 Rb2 -+> which forces a rook trade and therefore the game; if White would be able to keep the rook he'd be able to set up some kind of (albeit futile) counterattack. |
|
May-25-20 | | Predrag3141: White seemed oblivious to the piece activity he was allowing. For example, the retreat 15 Bd3? to preserve the two bishops dropped a little over a half pawn, according to Stockfish. Another example was the losing move: 26 Bxb7, allowing 26 … Rd2. In that move pair, Black's evaluation went up about 3 pawns. |

|
May-25-20 | | Predrag3141: <TheaN> After 33 … Ne2 34 Kh2 Nxg3 35 Kxg3 Rxg2 36 Kf4, 36 … Rb2 is a nice simplification. But Stockfish considers 36 … Rh2 a close second, and actually evaluates it as better until prompted with 36 … Rb2. |
|
May-25-20 | | Nullifidian: Temporary queen sac with 32... ♕xg1+ 33. ♔g1 and then 33... ♘e2+ forks the king and queen. The only way white can get something out of the wreckage is by playing 34. ♔h2 ♘xg3 35. ♔xg3, but then black responds with 35... ♖xg2+ and white will have three isolated pawns against black's strong pawn chain, an undefendable h-pawn, and be down the exchange and a pawn. I would be very happy playing this as black. |

May-25-20 | | TheaN: <Predrag3141: <TheaN> After 33 … Ne2 34 Kh2 Nxg3 35 Kxg3 Rxg2 36 Kf4, 36 … Rb2 is a nice simplification. But Stockfish considers 36 … Rh2 a close second, and actually evaluates it as better until prompted with 36 … Rb2.> Doesn't the Rh2 line eventually lead to Rb2 as well? It's these semi-forcing lines that engines can over evaluate on first glance 'h4 is in, White has to do something, so it's good'. SF9 gives 37.Ke5 Rc5+ 38.Kd6 Ra5 which is a unique line (after Ke5 Black can still revert to Rb2). Black wins another pawn but the White king's active and the rook still otb. I prefer the simplification. |

May-25-20 | | Damenlaeuferbauer: After long pondering and playing with his orange hat, my old Georgian friend Zviad, who was still 17 years young, finally found the winning of the exchange with 32.-,Qxg1+! 33. Kxg1,Ne2+ 34.Kh2/Kf2,Nxg3 35.Kxg3,Rxg2+ 36.Kf4/Kh3,Rb2 -+. This is how to play the Nimzo Indian with the black pieces against the dangerous 4.f3 variation. |
|
May-25-20 | | Pedro Fernandez: There is not forced mate here. All the moves are practically trivial. |
|
May-25-20 | | Pedro Fernandez: 32.Be4, mentioned by <Chris>, it is a lot better but the white saves it neither, given the pyrrhic white position. |
