| rodolpheb: 18.Nb5 then 19.Nxa7#
19...Kxb7 20.Qxb5+ Ka8(Kc8) 21.Qc6#
19...Kd7 20.Qxb5#
Where was black's mistake ?
14.dxc4 ? |

| patzer2: With 18. Nb5, the threat of the smothered mate 19.Nxa7# (or 19. NxQ) forces 18...BxNb5, which enables white's mate starting with 19. Bxb7+ to work. The three pretty mating variations after Bxb7+ are shown by Rudolpheb above. Note how, in this mating attack, white is utilizing the "removing the guard" tactic in a very subtle way. At first glance, the black bishop on d7 appeared to be holding black's position together so as to make the sacrifice with Bb7+ unworkable. However, by using 18. Nb5 to force the guarding bishop on d7 to a square where it can be recaptured with check, white effectively removes this guard in a three move sequence (18. Nb5 19. Bb7+ 20. QxBb5+) while simultaneously carrying out a mating attack. |

| patzer2: If instead of 10...Qxe5, black plays 10...dxc4, then 11. Bf4 b5 12. Bh5+ g6 13. Bf3 O-O-O 14. Nd2 gives white at least equality with good compensation and active piece play according to this chesslab.com computer analysis. |

| chessamateur: What about 18. QxQd4 cxQd4 19. Nb5! BxNb5
20. Rac1+ Bc6 21. BxBc6 bxBc6 22. Rxc6+ Kb7 23. Rc7+ Kb6 24. RxBe7? |

| patzer2: If 15...Qd3, then white gains the advantage with 16. Qe4! After 15...Qd3, the following variations appear to favor white according to chesslab.com computer analysis: (3.01 plus score) 16. Qe5 Qd4 17. Bf4 Qxe5 18. Bxe5 Be7 19. Bxh8 Nf6 20. Bg7 Rg8 21. Bh6 Rd8 (2.51 plus score) 16. Qe5 Bg7 17. Qxg7 Qd4 18. Re5 Ne7 19. Be3 Rdg8 20. Bxd4 Rxg7 (2.72 Plus score) 16. Qe5 Bg7 17. Qxg7 Qd4 18. Re5 Ne7 19. Bg5 One suspects this variation was a result of white's opening preparation and study, due to the fact that Romanishin initiates these complications so early in the opening. |

| patzer2: <rodolpheb> 14...d4 may be an improvement for black over 14...dxc4. Chesslab.com computer analysis recommends 14...d4 and offers the following variations as favoring black: (0.69 plus score) 14... d4 15. Ne4 Qe5 16. Ng5 Qf6 17. Qb3 b6 18. Ne4 Qe5 19. Qd3 (0.88 plus score) 14. ... d4 15. Ne4 Qe5 16. Ng5 Qf6 17. Qb3 b6 18. Qd3 Bd6 (0.93 plus score) 14. ... d4 15. Ne4 Qb6 16. Bf4 Nh6 17. Qb3 Nf5 18. Qxb6 axb6 However, I am suspicious that white may still have the advantage despite the computer's optimistic assessment for black after 14...d4. For example, in the second (0.88 plus score) line above, if white plays 19. Qe4 (after the end of the analysis of that line) it is white who resumes a strong winning attack. This game is deep, and even the computer seems to be struggling to find decent alternatives for black. Maybe Ivanchuk's mistake was in playing the French against a player as well prepared as Romanishin. |

| drukenknight: patz. I would encourage you to stay suspicious of the computers moves. Work the lines forward and backwards until you see a move that looks natural to you although the computer is not picking up on it. YOu may learn a lot about how computers think and how to beat them. The score that you see the computer give you, is in my opinion merely an analysis of the tactical/mating possibilities w/in the next 5 or 6 moves. There is no way for the computer to evaluate long range plans because that is not how they think. If you see the computer suddenly change the score to favor the other player that is a sign that you are onto something. if you see the computer give an ever increasing branches of lines, that maybe something. But be careful, it may have already taken you down the wrong road. If you see the computer grab material when it is already ahead in material, follow your intuition. it may surprise you. |

| drukenknight: perhaps 14...Ne7 or f6, the ending is quite a shocker. |

| Laskerfan82: Romanishin's gambit seems to have refuted Black's opening ... hard to see where Ivanchuk went wrong except in playing this opening! |

| whiteshark: I wouldn't play <6...f6>. It's premature this way. First development before center action. |

| whiteshark: Maybe there is a another way. The OE is showing <10...d4> - closing the center - with some good results
