  Marmot PFL: 41 Re6 Rd8 42 Re7+ Kf8 43 Rxh7 Rxd6 44 Rxb7 and white can create a passed pawn much easier than black.
Jan-14-13  Pedro Fernandez: Lamentably my #3 favorite defeated to my #2 one
Jan-14-13  DcGentle: White is about to win it, if he doesn't commit another blunder.
Jan-14-13  benjinathan: I think it could be a perp. Black will push the b pawn.

  lost in space: uugghh, just back and it looks grim for Black.

I think his only chance is to give 2 pawns (or even 3) to get the Pd6 - if it is not too late already

  chancho: Congrats to Vishy.
Big win over Caruana.
Jan-14-13  DcGentle: White will win the pawns on the kingside and invade with his king. Game over: 1 - 0

  chessdgc2: seems like Wang would play ...Kf8 instantly or resign...could there possibly be anything better?
Jan-14-13  DcGentle: For White this ending is only technique... he can do it.
Jan-14-13  Ulhumbrus: After 42...Kg8 43 d7 Kf8 44 Rxh7 b5 45 Kf2! gets within range of the b pawn and threatens 46 Rh8+ Ke7 47 Rxd8 Kxd8 46 h5! gh 47 g6 and Black's king can't stop both the white d pawn and g6 pawn
Jan-14-13  DcGentle: Another possibility is 42. Re7+ Kg8 43. d7 Kf8 44.
Rxh7 Kg8 45. Re7 Kf8 46. Re6 Rxd7 47. Rxg6 Rg7 48. Rf6+ Ke7 49. Kg4
Jan-14-13  Pedro Fernandez: <Ulhumbrus: After 42...Kg8 43 d7 Kf8 44 Rxh7 b5 45 Kf2! gets within range of the b pawn and threatens 46 Rh8+ Ke7 47 Rxd8 Kxd8 46 h5! gh 47 g6 and Black's king can't stop both the white d pawn and g6 pawn > +1.
Jan-14-13  DcGentle: So Black resigned already.
Congrats, Karjakin!

  Marmot PFL: In both wins today black resigns very early and without being down material.

  Marmot PFL: Actually there were 3 wins counting Anand.
Jan-14-13  DcGentle: Both players had their chances, but Black made the last mistake. This is only human. Nevertheless, <27. g4> was cool move. ;-)
Jan-14-13  Octavia: Karjakin did well - 2/2 ! Keep going Sergey!

  parmetd: I get it in Carlsen-Van Wley... But I don't understand why black resigned here. I see obviously Kf8 Rxh7 Rxd6 Rxb7 Re6... but then ... ? its not so clear to me. White is better but is this really so simple?

  perfidious: <parmetd> The problem for Wang at the end of your variation is that White ties down the enemy rook to defence with Rc7, then plays Kg4, followed by h5. Don't see any antidote to this.
Jan-14-13  haydn20: <parmetd: I get it in Carlsen-Van Wley... But I don't understand why black resigned here. I see obviously Kf8 Rxh7 Rxd6 Rxb7 Re6... but then ... ? its not so clear to me. White is better but is this really so simple? > In this line White plays 46. Rc7 and Black can't prevent the formation of a Kside passer AND defend the cP, and in some cases even the dP falls. OC, some better player than I may find a saving line.

  parmetd: thanks.
Jan-14-13  attica: <haydn20: n this line White plays 46. Rc7 and Black can't prevent the formation ...> That may be true, but this is not what the tournament site says. Look at the analysis after the resignation at the tournament website at http://www.tatasteelchess.com/tourn... The first line of computer analysis beginning with 42. ... Kf8 43. Rxh7 Rxd6 44.Rxb7 Re6... shows an evaluation of 0.91. They exchange rooks and the line ends with a maneuvering where neither side seems to make any progress (you can view the chess boards in the analysis by placing your mouse over the move). In the video at the official site, Karjakin does not say that Wang should not have resigned. There seems to be no video interview with Wang. The report at the official site gives no hint that the resignation may not have been justified. Can someone please explain all this, perhaps by improving on the computer analysis given at the site?

  Marmot PFL: <attica> White can improve on 46 Rxe7 with 47 Rb8+ Kf7 48 Rc8 Re6 49 Rc7+ Kf8 50 h5 with a winning rook ending. Still I probably have made white play a few more moves before giving up.

  Marmot PFL: <47 Rb8+ Kf7 48 Rc8 Re6 49 Rc7+ Kf8 50 h5 >

Should read 46 Rb8+ Kf7 47 Rc8 Re6 48 Rc7+ Kf8 49 h5.

The move numbers aren't important, just the idea that the rook trade is premature. If 46 Rb8+ Re8 however than 47 Rxe8+ kxe8 48 h5 wins, the difference being that after 48...gh5+ 49 Kxh5 c5 50 Kh6 the BK is on e8, not e7, so white queens with check.

Jan-15-13  haydn20: < attica > Here's the best I can do so far: 42...Kf8 43. Rxh7 Rxd6 44. Rxb7 Re6 45. Rc7 Re7 (...Ke8 46. h5 gh 47. Kh4 Kd8 48. Rh7 Ke8 49. Kxh5 Kf8 50. Rh6 wins) 46. Rxc6 Kg7 47. kf4 Ra7 48. Rd6 Rf7+ 49. Ke5 Rf5+ 50. Ke6 Rf3 51. Rd7+ Kf8 52. Rxd5 Rxe3 53. Kf6 wins. This is just me and a chess set and a spare half-hour. I'll feed the pos. to Fritz overnight, or maybe some kind soul who's my better will come along with better lines for Black.
