In the final position, Black is threatening mate following Nf3+, and White has no good defense. Rather funnily, the Houdini evaluation on the official site is -0.62, but that's apparently because of insufficient ply depth - it doesn't see that 42.Rh7+ Kc8 43.Rh8+ Kd7 etc. doesn't help White at all, since if the rook keeps checking like that the black king simply comes to f7, and after Rh7+ Kg8 there are no more checks. In the above line, White can also try 44.Bb5+, but after 44...Kc7! (bringing the king to the e-file loses to Re8+, of course) 45.Re8 (45.Rh7+ Kb6 and now the bishop is under attack) there's 45...Nf1+! 46.Bxf1 Rxe8.

Classic; once any reasonably strong human player works out the (not terribly complex) variations in which Black's king sidesteps, it is not at all difficult to discern K's fate.

  mike1: the result of the game will hide a really beautyfull combo by K starting with 25.Ne7. The position at move 32 is better for white; just do not give up the e4-pawn!

  Eyal: <master of defence> There's a quick mate there starting with 46...Ne3+! (which blocks the e-file)

46....Ne3+ 47.Kh2 g3+ 48.fg Ng4+ 49.Kh3 Nf2+ 50.Kh2 Rh1# I think.

Apr-24-13  Marmot PFL: Even though 27 Rxd6? is unsound let's give white credit for playing aggressively.
Apr-24-13  master of defence: <Marmot PFL>, i think that you mean 26.Rxd6?! threatening mate or win the black queen, but 29...Rxe7 finished all white's attack.
Apr-24-13  Jambow: I'm not seeing the mate either after 48. Rf8... Nf3+ 49. gxf3...Bxf3 50. Rxf4... Rh1+ 51.Kg3 and ah hah there it is Rh3# never mind.

  Gilmoy: <8.Qxd4 Nc6 9.Qe3>! It's just like 5m blue dot chess on pogo.com!

Rather funnily, the Houdini evaluation on the official site is -0.62....> Classic; once any reasonably strong human player works out the (not terribly complex) variations in which Black's king sidesteps, it is not at all difficult to discern K's fate>no, but it would probably take most reasonably strong human players more than about a minute to do that, which is plenty long enough for a decent engine. rybka jumped from -0.72 to -11.50 at depth 16, and it didn't take long to get there
Apr-25-13  sofouuk: incidentally, rybka isn't having any of this <26 Rxd6? is unsound>, either, although 'dubious'/'speculative' might be appropriate (instead 26.Nf5 would give white a small edge, it tells me). from move 26 to 32 it gives black a microscopic advantage (-0.10 at low ply), clearly playable OTB, and drops to 0.00 after 32...Nf6. the first mistake was the 'simple blunder' 33.a6? allowing Nxe4; just play 33.Bd3 and carry on

  Eyal: Btw, the winning line for Black that I gave in my first post might be a bit artificial, since it's more natural for the black king to stay on dark squares in order to avoid any tricks involved in checks with the bishop; so we could have instead 42.Rh7+ Kb8 43.Rh8+ Kc7 44.Rh7+ Kd8 45.Rh8+ Ke7, and now if White tries 46.Bb5 there's the nice deflection 46...Bc6! 47.Bxc6 Nf1+ and mate.
