| Dec-01-14 | | YoGoSuN: What about 20. Qxe1+ with the idea of Rd1+ ? |
|
| Dec-01-14 | | Shams: 20.Qxc4? Qxb6+  |

| Dec-01-14 | | notyetagm: Mamedyarov vs A Giri, 2014 Nimzowitsch's teachings about <PASSED PAWNS> also played a role in Giri's miniature Black win over Mamedyarov in Round 5. Mamedyarov vs Giri (5.1)
21 ... ?

click for larger viewHere Giri plans to play 22 ... ♕d1x♖e1+! 23 ♔f2x♕e1. Why? Because it replaces the White e1-rook <BLOCKADER> of the dangerous Black e2-passer, whose <BLOCKADE> *cannot* be broken, with the White e1-king, whose <BLOCKADE> of the Black e2-passer *can* be broken, with 23 ... ♖d8-d1+ 24 ♔e1-f2 e2-e1=♕  +. (THREATENING)
22 ... ♕d1x♖e1+! 23 ♔f2x♕e1

click for larger viewAfter Giri's excellent 21 ... ♖a8-d8! 1-0, White cannot really prevent this idea because his White b6-rook is <EN PRISE>. Nimzowitsch talked about this idea of <SUBSTITUTING ONE BLOCKADER FOR ANOTHER> in his treatise "My System". This game fragment from Giri makes an *excellent* example. |

| Dec-02-14 | | coolconundrum: Thanks for the analysis but what's up with the long descriptive notation?! Really hard to look at. ♔f2x♕e1 can much more simply expressed as KxQ :) |
|
| Dec-06-15 | | greed and death: 17... dxe3 looked nice and so I went with it, although I expected 18. Bxc6 instead of Rxb6. I'll give myself credit though... ;) |

 | | Penguincw: On this date in history 26 years ago, a man entered a Montreal University and shot and killed 14 women, injuring 14 others. This event is known as the "Montreal Massacre". In Canada, December 6th marks a National Day of Remembrance and Action on Violence Against Women. As for this actual puzzle, the only thought that came to my mind was a capture on d3, but I did it with the wrong piece. But hey, Monday's tomorrow, right? |
|
| Dec-06-15 | | patzer2: Seemed easy for a Sunday puzzle as I quickly found 17...exd3! and the next three moves in the game. However I bombed on the fifth move of the combination with 21...Qxe1+??, which lets White turn the tables and swindle a win after 22. Kxe1 Rad8 23. Qxe8+! . Instead of 21...Qxe1+??, the solid follow-up 21...Rad8! easily wins the game for Black. |

| Dec-06-15 | | dunamisvpm: IMHO the degree of difficulty should not be put in the the category of "insane" level. Have fun! GOD Bless |
|
| Dec-06-15 | | morfishine: <17...exd3> is easily found |
|
| Dec-06-15 | | Mehem: Frankly speaking, the final position isn't as easy to win as some would expect. 22.Qxe8+ Rxe8 23.Rb4 and we have R+B vs Q. |
|
| Dec-06-15 | | Captain Hindsight: Better would have been < 16. dxe4 Bxe4 17. Qb3 > to avoid passed pawn troubles. |

 | | agb2002: Black has a bishop and a knight for the bishop pair and one pawn. White threatens 18.Qxc6 and 18.Bxe4.
The white rook does not have free squares. This suggests 17... Qc8: A) 18.Bxe4 Bc4 (18... Qxb7 19.Bxc6 and White seems to end up two pawns ahead) A.1) 19.dxc4 Rxe4 20.Rxb6 axb6 21.Nd4 Nxd4 22.cxd4 Rxa2 with an exchange for a pawn and a won position (23.Qxb6 Ree2). A.2) 19.Qc5 Rxe4 looks similar to A.1.
B) 18.Rxb6 axb6 19.Bxe4 Bd7 20.Qxb6 Rxa2, unclear [R vs B+2P]. That's all I can do today. |

| | agb2002: It's curious I had a similar idea, Bc4, but my version, or hallucination to be precise, fails horribly because of 19.Qxc6. Do not rush, do not rush, ...
No way. |
|
| Dec-06-15 | | Marmot PFL: <Mehem> I was thinking that too. Lots of work left for black. Some players lose heart in bad positions, while others (Fischer for instance) will fight to the death and often save the game. |
|
| Dec-06-15 | | Moszkowski012273: Was 18.RxN... whites best chance? |
|
| Dec-06-15 | | FlashinthePan: <Whitehat1963: Obviously, I'm blind. Someone please tell me what happens if 20. Qxc4.> 20...Qd1 also wins |
|
| Dec-06-15 | | Cheapo by the Dozen: I don't understand 18 Rxb6 at all. Why not Bxc6 instead, which incidentally attacks e8, and specifically the rook currently occupying e8? |
|
| Dec-07-15 | | FlashinthePan: <Cheapo by the Dozen> After 18.Bxc6 the black knight on b6 allows 18...Bc4, whereupon White is in deep trouble. |
|
| Dec-07-15 | | CHESSTTCAMPS: In this open middle-game position, black has a knight for a bishop and a pawn with dynamic counter-play, given the overextended look of the Rb7. Nonetheless, white threatens both Qxc6 and Bxe4, with active play along the LSB's long diagonal. Direct attempts to exploit the trapped rook backfire, e.g. 17... Qc8? 18.Bxe4 Qxb7 19.Bxc6 looks strong for white. Instead, black should take full advantage of counter-chances along the a6-f1 diagonal supporting a passed pawn: 17... exd3!
A. 18.Bxc6 Bc4! 19.Qb1 dxe2 20.Re1 Qd1 21.Be3 Qxb1 22.Rxb1 Red8 23.Re1... Hmm - white seems to hold. All I have time for... |
|
| Dec-07-15 | | CHESSTTCAMPS: I had the right theme, but didn't do very well with the detail. I recall that Giri upset Carlsen with black in a similar type of game. |
