 | | wwall: Perhaps White can play 38.Rxd7+ Bxd7 39.Qf7+, since 39...Qxf7 40.Rxf7+ Rg7 fails to 41.e6. If 38...Bd5 (threatening 30...Qg2+), White can play 39.Qg4. 39.Rxc5?? Qg1 mate.
If 39...Nd3, then 40.Rc7+ Kh8 41.Qf6+ Qxf6 42.exf6 Rf8 (42...Nxf2 43.f7+ Rg7 44.f8=Q+ Kh7 45.Qxg7 mate) 43.Rf3 Ne1 44.Re3, winning a piece. 40.Qe3 is bad. Perhaps best is 40.h4. Maybe 40.a5 can also be played. After 40...Nb3, if 41.Rd1 Nxd4 42.Qxd4 (42.Rxd4 Qg1 mate) Qg3+ 43.Kh1 Qxh3+ 44.Rh2 Qf3+ 45.Rg2 Qxg2 mate. |

| Jul-16-12 | | henjutsu: Well, of 40. a5 or h4 is played, then black responds Nd3? Looks painful. And white can't let the c1 rook move off of that rank due to Qg1++. Or if the f2 rook moves, Qg2++. Or if the queen moves, Qg3+. Kh1, Bd5+. And all three would be under attack there. I think that's why he moved the queen.
I like your 38. Rxd7 idea. I've played a few variations and I can't save black. |

 | | perfidious: Where's the win after 38.Rxd7+ Bxd7 39.Qf7+ Qg7?
click for larger viewBlack has threats of his own, so I don't see anything better than 40.e6 Bxe6 41.Qxg7+ Rxg7 42.Bxg7 Kxg7 and maybe White can draw, but I'm not even sure he can do that. |

| Jul-16-12 | | shivasuri4: <perfidious>, in your line, you need to change the order of the moves. After 40. Qxg7 Rxg7 (Kxg7 would be a blunder) 41. e6 Bxe6 42. Bxg7 Kxg7, white is slightly ahead, I suppose. An alternative line is 41...Re7 42. exd7 Rd7, where white is slightly better again. |

|
| Jul-16-12 | | shivasuri4: <perfidious>, yes, you are right. The only difference is that black gets an alternative in my second line, which may be worse for him. Can you accurately evaluate the resulting position? I am unable to. |

| | perfidious: <shivasuri4> Looking at the resultant position a little, this is unclear. If Black gets his queenside pawns going, he's winning, but White's rook is active.
After the simplification in my hypothetical line of 38.Rxd7+ Bxd7 39.Qxf7+ Qg7 40.e6 Bxe6 41.Qxg7+ Rxg7 42.Bxg7 Kxg7 we would have this position:
click for larger viewWhite's best move looks to be 43.a5, after which a reasonable continuation seems 43....b6 44.axb6 axb6 45.Rf4 b3. In this, White can win the b6 pawn, but with so little material on the board, I don't know what winning chances he has. Carlsen would probably squeeze this out though! |
|
| Jul-16-12 | | shivasuri4: <perfidious>, right, thank you, had that very end position in mind. Interestingly, Bill Wall analysed the same possibility in the first post on this page, but seemingly had a different conclusion. |

| Jun-12-13 | | marljivi: Even if white's position may still be winning after 37.e5?,the move looks really ugly to me,even for being in time-scramble.I mean-to close such a powerfull bishop on b2...Instead 37.Rd2...(the threat being Qd6,followed by Rxd7) 37...Rf8 38.Qg3Rf7 (38...Rg8 39.Qd6  ) 39.Rg2...(39.Rb7!? ) with the double threat Qg6mate and Qg7Rg7,Rg7Kh8,Re7 .No defence,for example 39...Re7 40.Qg7Rg7 41.Rg7Kh8 42.Re7 .So, . Most probably up to 37.e5? Uhlmann played really brilliantly. |
