|Nov-03-07|| ||kevin86: I saw the principle,if not the solution. I saw the possibility of N@d4 moving-setting up queen traps at b6. It was a fine finish as the lone queenside pawn takes all of the strength of the black forces. The pawn will cost a rook-and even a trusty steed cannot hold up against a mighty queen.|
|Nov-03-07|| ||playground player: Mr. Bronstein didn't give up too easy, did he?|
|Nov-03-07|| ||al wazir: <dzechiel: White to move. Well, the first thing that jumps off the board at me is the precarious position of the black queen.>|
I never saw the win of the ♕. The first thing that jumped at *me* was the precarious situation of the black ♗s. I would have played 16 Nf3, threatening 17. e5.
I haven't found any good defense. If 16...g6, then 17. e5 Bg7 18. exd6, with a nice advanced passed ♙.
Or maybe I would have seen 18. Bb6.
|Nov-03-07|| ||patzer2: For today's puzzle solution, Gipslis' 16. e5!! sets up the double attack sham sacrifice 17. Nxe6!, which threatens to trap the Queen if Bronstein captures the Knight (i.e. 17...Bxe6 18. Bb6 ) or to win the exchange with decisive advantage if he doesn't (i.e. 18...Qh5 19. NxR ).|
Bronstein's 18...Qxb6 offered a decent practical chance to hold, but was insufficient against Gipslis' material advantage.
|Nov-03-07|| ||Alphastar: <kevin86: I saw the principle,if not the solution. I saw the possibility of N@d4 moving-setting up queen traps at b6.>
I think the main point of the combination was not that the queen could be trapped; but that it could be trapped under favourable circumstances after 16. e5!! . Going after the queen immediately is pretty bad, the move e5 is the key to victory here.|

Doesn’t 16…Bxc3 immediately stop that threat? If 17 bxc3 then 17… Qxa3 wins a pawn.
If 17 e5 then 17... Nd5 18 bxc3 Qxc3 19 Bd2 Qxb3 wins two pawns.
|Nov-03-07|| ||InspiredByMorphy: I thought it was 16.Nf5 with 17.B6 in mind. Right idea but wrong execution. Clearing the d file and attacking the bishop on d7 with 16.e5 and 17.Nxe6 has to be better.|
|Nov-03-07|| ||fm avari viraf: My first reaction was 16.Nf5 threatens to trap the Queen & if ...Qc7 or ...Qd8 17.Nxd6. But after, 16...exf5 17.Bb6 Bxc3! 18.Bxa5 Bxa5 winning three pieces for the Queen not a bad bargain! After, a little more thought, I could spot 16.e5! attacking the Bishop as well as blocking the Bishop's diagonal ...dxe5 17.Nxe6 with multiply threats & Black is on the horns of dilemma. Of cousre, I don't see an immediate win but a ding dong battle is in the offing.|
|Nov-03-07|| ||Kings Indian: This was easier than the tuesday puzzle for me...|
|Nov-03-07|| ||MaczynskiPratten: I think Bronstein fancied his chances with two minor pieces against the queen more than a straight exchange down. In fact, the key to Gipslis' success may be that he could swallow the b and a pawns as well, otherwise the ending wouldn't be so clearly winnable.|
|Nov-03-07|| ||al wazir: <Jimfromprovidence: Doesn’t 16…Bxc3 immediately stop that threat?>|
You're right, it looks like a perfectly good defense. I don't know how I missed it. But after 17. bxc3 Rxc3/Qxc3 18. Rxd6 I'm not sure it wins a ♙
|Nov-03-07|| ||Jimfromprovidence: <al wazir> <You're right, it looks like a perfectly good defense. I don't know how I missed it. But after 17. bxc3 Rxc3/Qxc3 18. Rxd6 I'm not sure it wins a pawn.>|
I posted 17… Qxa3. I think that wins a pawn because it also protects black's d pawn.
|Nov-03-07|| ||willyfly: Material is even. The first thing I notice is that Black's ♕ and d6♙ are without defenders. I also notice that the Black ♕ can be easily driven from it's current square by the ♙ push b4 and it doesn't have many safe squares to move to. Particularly dangerous for the ♕ is b6 viz 16 b4 ♕b6 17 ♘xe6 ♕c6 18 ♘xf8 where White wins a ♖. Pushing the b3♙ also has the effect of providing a defender for White's only undefended man.|
I've been studying this position for a while now and I haven't found anything worth posting besides the above observations. I don't have any specific lines to offer but I believe the solution will be an attack on the vulnerable position of the ♕. Time to look.
I probably never would have got this but I will remember the pattern of the ♗ and ♕ (I hope)
|Nov-03-07|| ||Poisonpawns: Easy puzzle i saw e5 right away because Bd7 is just hanging:-).Looking at oppenents weaknesss first will guide your attack.Now the move Nxe6! i saw after making e5 on my board with the queen trap.|
|Nov-03-07|| ||PositionalTactician: Marmot PFL: The only flaw in black's game I could see was the Qa5 could be cut off by Bb6 if the 5th rank was also blocked. So e5 de5 Nxe6 and Bb6 traps the queen after either Bxe6 or ef4.|
As far as Bronstein not resigning in a lost position, it was not a simple win even after winning the queen, and if black had played 38...Ra5 stopping the a pawn, followed by g5 and then Ng6 (or Nf3 if white plays h3) it would be even harder for white. many such games have been saved by putting up tough resistance when the opponent is already counting the game as a win after a successful trap.
Reply: Well, Marmot, I dont think that would have drawn the game. Firstly, if you have played ...g5, then the king is too open. I have chances like Qf7 winning the knight. Also, even if you want to build a fortress, and , say, sacrifice your knight for the a pawn, you will quickly realise that in order for the fortress to work, your g-pawn has to go back to g7. Therefore, I dont think Black can draw if he had played ...g5 and Ng6
|Nov-03-07|| ||Marmot PFL: <PositionalTactician> I don't think he would draw either, but there was slight chances (I thought) based on stopping the pawn as long as possible and then trying to get some counterattack with R+N supported by the f pawn. Probably not very realistic but just giving white some chance to go wrong. After move 40 in the game it was pretty hopeless I agree.|
|Nov-03-07|| ||al wazir: <Jimfromprovidence: I posted 17… Qxa3.>|
My mistake. OK, let's look at this again. 16. Nf3 Bxc3, and now 17. Rxd6 Bc6 (17...Bb5 18. Bb6) 18. b4 Qa4 19. bxc3 Qxa3 (19...Bxe4 20. Ng5) 20. Qc2. (This time I set it up on a board.)
|Nov-03-07|| ||black knight c6: Firstly,
18. ... Qf5 19. Nxf8 Kxf8 20. Qxf4
Simply leaves black a bishop for a rook. It might've simply been a little bit lesser of two evils. I'm not sure. I think perhaps this line <might've> been better considering how well Gipslis managed to finish off the game line. But that's all with extra dollops of hindsight.
Secondly, is something like:
17. ... Bxe6 18. Bb6 Rxc3 19. Bxa5 Rxb3 (20. fxe Bxe5)
Better than the game continuation? Or worse?
|Nov-03-07|| ||eblunt: Possibly add some complication with 18 ... ♗h4 ??
At least sets the trap for 19 ♗xa5 ??
|Nov-04-07|| ||newton296: <znprdx: nope ...I think the Fat lady won't have that much time to choose even her swan song :) 19...Bg4? how do you do that with the Queen on f5 - you must be moving the pieces tsk-tsk >|
okay, if you read my post you would see that I said 18)...Qh5 gives the B somewhere to run to . not 18)...Qf5 .
I reposted the text you claim incorrectly was in error as exibit A !
<<Qf5 and Qh5 save the B ! Qf5 covers it directly . and Qh5 gives the B somewhere to run. Bg4 attacking whites rook . You will notice the knight can be picked up later as it has no where to go. so white has time for Bg4 picking up the knight later.>>
|Nov-04-07|| ||Jimfromprovidence: <al wazir> <My mistake. OK, let's look at this again. 16. Nf3 Bxc3, and now 17. Rxd6 Bc6 (17...Bb5 18. Bb6) 18. b4 Qa4 19. bxc3 Qxa3 (19...Bxe4 20. Ng5) 20. Qc2. (This time I set it up on a board.)>|
I would play after 18 b4 18...Qc7. Then 19 Rdd1 Bxb4 20 axb4 Bxe4 I hope retains the pawn.
|Nov-04-07|| ||al wazir: <Jimfromprovidence>: 18...Qc7 19. e5 Nf5 20. Bb6 Qb8 21. Rd3. |
Let's drop it now. My line is clearly inferior to the one white played.
|Nov-05-07|| ||rhedrich: 18...Qf5 and I still don't see how Black's worse than the text. 19.Nxf8 Kxf8 is next (19.Rxd7 Qxe6). Then what does white do? Take the f4 pawn? 20.Qxf4 Qxf4 21.Rxf4 Be6 22.b4 Bxc3 23.bxc3 Rxc3 and white is still only up the exchange for an extra black pawn. Is this right, or does white have a better alternative? If not, I'd take this line over the text any day.|
|Nov-07-07|| ||al wazir: <rhedrich>: You're right. Bronstein must have seen a ghost left over from Halloween.|
|Dec-06-08|| ||GrahamClayton: I read somewhere that Bronstein took 18 minutes of thought before playing 1...c5 in response to Gipslis' move of 1. e4.
Can anyone confirm this?|
