| Autoreparaturwerkbau: 25...b3! is the cream on the top of the cake. Astounding! |

| beatgiant: Is Black still winning after 22. Re8+ instead?
I see 22. Re8+ Kf7 23. Rc8 Ke7 24. Rxc7+ Kd6 25. Ra7 Bd5 26. Ra6+ Kc7 looks practically forced, and then White can try 27. b4!? and Black won't get connected passers, although it still looks like good winning chances for Black. |

| Cyphelium: <beatgiant> At the end of your line,
click for larger viewwhat is wrong 27.- cxb4 and then b4-b3-b2,  e4 and so on? White can't even get the rook back to the first rank, so he will eventually have to sac the knight for the b-pawn. And then there's another b-pawn... |

Right, 27...cxb4 is the obvious winning try. It's already a long line, so I didn't take it further. Black probably does win, but some care might be needed as from the diagram 27...cxb4 28. Nd2 b3 29. f3 b2 30. Kf2 Bc4 31. Ke3 prevents the immediate win as you described. |

| Cyphelium: <beatgiant> On 27.- cxb4 28.  d2, perhaps 28.- c3 is best. Then 29. b1 e4 must be good for black, for example 30. xc3 bxc3 31.  a1 b4, winning (I guess). |

One thing I missed was 27...cxb4 28. Nd2 b3 29. f3 b2 30. Kf2 <Bb3> which does look like an immediate win.I do think White needs to get the rook behind the passers, which is why I originally thought of 22. Re8+, but that doesn't happen in the lines we studied above. At this moment, I believe Black is winning. |

| beatgiant: My other try for White would be 24. Ra1 from the actual game. |

| Cyphelium: <beatgiant> 24. a1 looks like a good try. After, say, 24.- b3 25. a8+  h7 26. c8 c3 27. bxc3 bxc3 28. xc7 c2 29. f2, white can perhaps even play for a win. |

Agreed. Maybe Black needs to improve earlier in this game, for example 22...g5 to prevent White from supporting his knight post. |

| beatgiant: On 22...g5, if White tries to get his rook behind the pawns with 23. Ra1, then <23...Bxe5> 24. Rxa2 is a good trade for Black. After due preparation, Black can play ...c4 and ...c3, getting two connected passed pawns and probably winning. Also if White tries to reinforce the knight after 22...g5 23. g3, then <23...g4> freezes the kingside pawns. So probably White prepares to reinforce the knight with 22...g5 23. f3, and it goes something like 22...g5 23. f3 Bd5 24. g3 c4 25. f4 <Be4>. The knight is still feeling undermined since Black can later trade with ...Bxe5 and attack the e-pawn. I think Black's on top. Again this is a long line, so I'll wait for others' comments before taking it further. |
