Jun-26-13  Dr. J: 30 Qc5+ is a 'mistake': 30 Rb4+ is a move quicker.
Jun-26-13  MoonlitKnight: Among the top players, Ponomariov probably has the latest resignations, although another contender is Morozevich.

Jun-26-13  stacase: Moves like 28 Rb5+ don't always pan out, but in today's position it was just the ticket. I didn't see it right away, and it took a little bit to see that it would work.
Jun-26-13  zb2cr: The main line is 28. Rb5+, cxb5; 29. Rd6+, Kc7; 30. Qd7+, Kb8; 31. Rb6+, Ka8; 32. Qb7#.
Jun-26-13  dark.horse: White as much more than enough material to mate, so he can waste a rook to flush the king into the open. 28. Rb5+, and that's it.
Jun-26-13  anandrulez: Yes , in puzzle mode this is direct . OTB it might be 3 stars i.e a 2000 player might find it ...and the thing is to get a position like this and know its winning line u need to be a GM :-)

  playground player: I have found that after having done a couple thousand of these puzzles, I do sometimes find these moves OTB.

  kevin86: i saw this one quickly,the rook sac at b5 is followed quickly by mate whether or not black accepts the sacrifice.
Jun-26-13  geeker: The last two days' positions/solutions I remembered, having followed the original games live. Weird, I thought the Tregubov-Ponomariov game was much more recent than 2008 - my memory's usually not that good.
Jun-26-13  BOSTER: <Dr.Funkenstein> <The tactical possibilities should favour white so we would be looking for these with or without knowwing this was a puzzle position. Because it is puzzle, the winning move jumps out immediately>.

First you said, that you can see the solution even in the OTB, then you said that you see the solution because it is puzzle. Don't you think that this is a contradiction.
I'm sure that if you had such pos. in OTB , you would never think about Rb5.

Jun-26-13  Dr. Funkenstein: I said it is easier to see the solution because it is a puzzle, but that in OTB at this point in the game, white would be looking for these tactical possibilities anyway because the position favors white's centralized position and more active pieces.

Jun-26-13  BOSTER: <Bartimaeus Playing through the game it seems black made a series of errors>.

I don't think so.
My opinion that black made only couple invisible mistakes. First, I'd prefer to play 21...Rhe8, to move "h" rook on e8 instead 21...Rae8, because in some lines after exchange on d5 rook on h8 is hanging in the air. Second, before playing 26...bxc6 I'd play in-between move 26...Qc4+ to activate the queen and then 27...bxc6.

After such small changes we have the pos. with white to move. Certainly , white a little bit better, but black could draw such pos.

That is not how I understood your comment at all. And nor do I think anyone else at <chessgames> does. The implication, as I saw it, was that you consider yourself capable of solving any puzzle however hard that you are set. AND you think everyone else is garbage. Why do you think these things? Who annoyed you?

Jun-26-13  James D Flynn: Material is equal but White’s pieces are more coordinated and dominate the centre. 28.Rb5+ cxb5 29.Rd6+ Ka7(if Kc7 30.Qc5+ Kb7 31.Qxb5+ Kc7 32.Qc5+ Kb7 33.Rb6+ Ka7 34.Qxa5#)30.Qc5+ Kb7 32.Rb6+ Ka8 33.Qc6+ Ka7 23.Qb7#
Jun-26-13  Patriot: Time: 3 minutes

28.Rb5+

28...cxb5 29.Rd6+ followed by 30.Qd7+ etc.

28...Kc7 29.Qd7#

28...Ka6 29.Rxa5+ looks winning.

Jun-26-13  Abdel Irada: <<•> "A little calculation practice" <•>>

As so often, <Phony Benoni> has pointed to the essence of the puzzle.

Noting the isolation of Black's king and the queen standing in the left outfield, it is natural enough to look for a combination that lets the queen and rook penetrate and mate.

As <whiteshark> might tell us,

<<•> 28. Rb5†! > and that's it!

I'm tired and lazy today, so I'm not going to examine each line (especially since that has already surely been done by others). But I will say that it doesn't require deep analysis to prove that White wins in all of them. Exactly as <PB> suggested: "calculation practice." :-)

Jun-26-13  IPrometheus: I saw Rb5+ in about 2 seconds
Jun-26-13  geniokov: <28.Rb5+> and GAME OVER!
Jun-27-13  Abdel Irada: <IPrometheus: I saw Rb5+ in about 2 seconds>

That's nothing. I saw Rb5† 0.0013 seconds into the Big Bang.
