|Oct-06-09|| ||kevin86: Shame on you black for forking mu queen and knight-I have bigger fish to fry-a fork of rook and rook.|
|Oct-06-09|| ||Samagonka: This was not easy.|
|Oct-06-09|| ||JaneEyre: <I think that these "diagonal forks" are perhaps easily overlooked - there is a game somewhere in the CG database where Karpov failed to see such a fork, and had to resign immediately.>|
Christiansen vs Karpov, 1993
|Oct-06-09|| ||TheChessGuy: Took me awhile. I saw Qf5!, but didn't realize that it forked Black's rooks right away. It's odd to overlook things like that, as Rabczewsky found out when he/she played 29...e5? Unusual for such a quiet move to solve a Tuesday puzzle.|
|Oct-06-09|| ||antharis: Btw 29. Bd4 looks like white want to lure black into that trap as <al wazir> pointed out below. Taking into account black wouldnt make any mistakes, 29. Bd4 is not the best move for white I suppose. So 30. Qf5 dont deserve a "!" but 29... e5 an "?". ^^|
After 29. Bd4 Qe8 black has some nice options and now its white that has to move the bishop, because the pawn fork will work now and black has always the option to play the queen to the active g6 square to threaten a mate on g2...
|Oct-06-09|| ||ZUGZWANG67: White has a nice fork at f5 but the WB is en prise. The problem is that I can' t find a way to save the B and preserve the pin, as 30.Bc5 Qf7 31.Qf5 Rcd8 is nothing. The presence of a white piece at d4 thus garantees the success of the fork.|
30.Qf5 Rxd4 31.Qxc8+ Qe8 wins the exchange.
Time to check (GULP)!
That was it.
|Oct-06-09|| ||AnalyzeThis: 29....e5 was terrible. It forces white to make a winning move.|
|Oct-06-09|| ||YouRang: Yes, 30.Qf5 is the only sensible move.
But that didn't stop me from spending a couple minutes looking at some silly moves.
|Oct-06-09|| ||al wazir: <eaglewing: . . . Certainly there are better moves than 29...e5 but your 29...Rd8 looks like an inferior one: 30 Bb6 R8d7? 31 Qb8+, so the rook has to move again on the 8th row. I think I would prefer 29...Qd7 30. Bc5/b6 e5 and Rc8 might move next.>|
<JeffCaruso: If 29 ... Rd8 then 30. Bb6 would force the R to move off the d-file.>
I agree. 29...Qd7, followed by 30...e5, is better. With that correction, I stand by my comment. 29. Bd4 looks like a move intended solely to sucker black into making a blunder. It may have won, but it's not a winning move against any but suckers.
|Oct-06-09|| ||newton296: i thought, and thought, and thought, and thought, but notta, zip, zilch . |
looked and solution and wow ! Qf5 fork , so easy why didn't I see it.
I spent an hour looking at this too !
|Oct-06-09|| ||estrick: After 28. . . . Rxd3, Black seems to have command of the d file. White cannot immediately challange Black for control of the file without leaving the bishop hanging. The bishop is also in a passive position on c3.|
29. Bd4 gets the bishop to a more active square, preparing to post it on a square where it can't be dislodged, thereby freeing up White's rook on c1 from having to defend the bishop, and it prevents Black's rooks from getting 'in communication' with each other which might lead to a major invasion of White's side of the board.
Seems like White accomplishes quite a bit with that move, besides setting up a potential tactic, which Polgar probably did not expect Black to fall for.
|Oct-06-09|| ||Check It Out: After looking at 30.Bc5, Re1 and even Bxe5, I spotted Qg4 after noticing the loose rook on c8. However, that wouldn't work and then finally Qf5 found it's way into my vision.|
|Oct-06-09|| ||lzromeu: Its easy if you don't look for a checkmate or some like this.|
I spent 1/2 hour at this, trying back rank mate or trap the Queen.
Qf5 is the only good move for white. So close in the board, so far for the eyes.
|Oct-06-09|| ||Patriot: <<al wazir> <29. Bd4 looks like a move intended solely to sucker black into making a blunder.>|
I disagree. The nice thing about Bd4 is that it allows for Bc5 or Bb6 in some lines. I'm sure Sofia saw that Bd4 is a good positional move that is tactically sound, while allowing the possibility of an e5 blunder. GM's make moves all the time that improve their position while giving their opponent the opportunity to make a mistake.

Hi, <newton296>. Here's how to see it instantly: look for loose pieces after checking safety of the opposing K. With the 2 loose Rs (Rc8 and Rd3) and a threatened Qf4, I checked for flight squares from which the Qf4 could fork...and (as they used to say in the Hanna-Barbera cartoons): viola! The fork at f5 just screamed to be played.

All you ever wanted to know about named checkmates.
|Oct-06-09|| ||muralman: Monday and Tuesday were nice finger stretchers. Today's took some looking at several enticing moves. After some board search, and a little soul searching, I elected to take the one up-manship and split the rooks.|
|Oct-06-09|| ||johnlspouge: At ply 15, Toga evaluates Move 39. as follows:
value (to White) -0.74 P
value (to White) -0.25 P
On one hand, even with the error in Toga's evaluation function considered, 0.5 P is slightly more than a matter of taste and near the (fuzzy) borderline of an inferior move.
On the other hand, 29.Bd4 does actually entail the trap that ended the game.
Alas, it would be instructive to know White's reasoning behind 29.Bd4, but...

Not quite, but thanks, I noted it.
|Oct-06-09|| ||The Rocket: this is interesting because it really isnt that easy to see..... in a blitz game I could for sure miss a move like that.|
|Oct-06-09|| ||WhiteRook48: 30 Qf5 is so easy|
|Oct-06-09|| ||briiian13: could have played on|
|Oct-06-09|| ||jackpawn: I found it in a few seconds. Looked for possible sacs, didn't find any, then looked for loose pieces. Bingo.|
|Oct-06-09|| ||openingspecialist: This puzzle illustrates how I evaluate a game. If I have coordinated and protected pieces, and my opponent does not, I'm winning even if I am a pawn down. This reminds me of the last tournament game I played.|
|Feb-17-12|| ||Travis Bickle: Is this from Sophia's famous tournament called 'The Sac Of Rome'?|
