 | | FSR: I tried submitting "Open and Schut" for this pretty game, but someone beat me to it. |

Jan-22-13 | | Abdel Irada: It appears White could have won a pawn rather fetchingly with 15. Bxe7, Qxe7 16. Nxe5, Bxb3 17. axb3, Qxe5 18. Rd5. |
|
Jan-22-13 | | Abdel Irada: On the other hand, that rook-and-queen sacrifice of Schut's is well worth the price of admission; for that move we can forgive all the errors that came before it. |

Black has several interesting alternatives on move 16: 16...Nxg3, 16...Nxb2, and 16...Nxe5 17.Bxe6 (17.Qxh5 Bg4) fxe6 18.Qxh5 Rf3, when White's queen is awkwardly placed and Black threatens tricks like 19...g6 20.Qh6 and now 20...Rxf2 or 20...Ng4. |

 | | FSR: Houdini gives Hakimifard's 17.Nd5 as best (+.43). It says that 17.Nxe5? is bad: 17...Nxb2! (-1.11) and 17...Nxe5 18.Bxe6 fxe6 19.Qxh5 Nf3+ 20.Kg2 Rc5!, when White's best is to sac her queen with 21.Qxf3 (-0.89), are both strong responses. My third suggestion, 17...Nxg3?, is much weaker, leading to a minimal advantage for White (+0.25). |

Jan-23-13 | | Abdel Irada: <FSR>: I think you're looking at the position after 15. Rac1, Nc4. Have another look without inserting that move-pair. Black's options seem far more limited. |

You are quite right. I <had> thought it odd that you had overlooked so many possibilities for Black. But isn't Nxg3 still OK for Black (15.Bxe7 Qxe7 16.Nxe5 Nxg3 17.hxg3 dxe5)? |

 | | FSR: Houdini 3 gives 15.Bxe7 Qxe7 16.Nxe5 Nxg3 17.hxg3 Nxb3 18.axb3 (or 18.Nc6 Rxc6 19.axb3 Qg5) dxe5 19.Nd5 Qg5 with a minuscule advantage for White (+0.19). |

Jan-23-13 | | Abdel Irada: Yes, you're right. Tactically, 16. ...Nxg3 does appear to retain material parity. Strategically, however, I would still prefer White after the series of moves in your last post. With 20. Qd2, White all but forces the queens off, and after 20. ...Qxd2 21. Rxd2, Nxb3 22. axb3, Rc5 23. c4, Black seems to be faced with unpalatable choices: Keep minor pieces on when the knight is so dominantly placed, or exchange and give White a strong passed pawn. Black, of course, still has plenty of play, and the end is far from foregone. But this looks to me like one of those positions where engines perceive only a nominal advantage, and then suddenly a few moves later, the evaluation swings radically in favor of one side. Still, you're correct in pointing out that I was hasty in saying White won a pawn, which is obviously untrue. |
