 | | cu8sfan: This game is very interesting. I found it in Ludek Pachman 's <Modern Chess Strategy>, a great book which I value more than Aron Nimzowitsch 's <My System>. The content of these two books is about the same but the explanations in Pachman's book are much clearer for a patzer like me. About this game Pachman writes "White attacks the enemy centre by piece pressure combined with pawn pressure from the sides; he finally destroys it by advancing his Queen-pawn, which had been held back in reserve." I really think this game deserves some attention. |

| Jul-05-05 | | Mating Net: I agree <cu8sfan> this game does deserve attention. I think the exchange sacrifice 26.Rxg7! is quite clever. It allows the followup 27.Re8 which essentially freezes 3 Black pieces on the back rank. White wins by exploiting the resulting pin. |

| Dec-21-16 | | zydeco: <WhiteRook48> Pretty line. But 32...Kf7 33.Qe7+ wins a rook. Pachman was masterful with both the Closed Sicilian and the English. I'd never noticed before this game that the openings have a lot in common. White pushes the f-pawn early, concedes some ground in the center (usually the d4 square), and slowly develops a kingside attack in front of his own king. |
|
| Nov-29-19 | | devere: Since 25.Re7 is obvious and 25...Qxc4? isn't forced, this would be a better problem on White's 26th move. |

 | | An Englishman: Good Evening: Solved the puzzle, but the interesting moment consists of 13.f4, because Black could have replied 13...exf4 and 14.Nxf4 allows 14...Nxg3. 14.gxf4 seems forced, unless White has some trickery after 13.f4,exf4; 14.Nxf4,Nxg3; 15.Rf3,Qh4; 16.Bf2. |
|
| Nov-29-19 | | Dionysius1: Good Morning <An Englishman>. Isn't your 16.Bf2 the end of the line for Black - a N for a pawn down without compensation? |
|
| Nov-29-19 | | Carrots and Pizza: Is this a correct puzzle? Correct me please if I'm wrong, but this doesn't seem like a true tactical puzzle. |
|
| Nov-29-19 | | TheaN: I <do> think this Friday is supposed to start at move 25, as White can play 25.Re7! ± at virtue of 25....Qxc4?! (Qg6 ± holds for now but Black isn't exactly doing great), 26.Rxg7 +-. I didn't calculate it entirely, but was confident we could sac c4 due to the first three moves of the game line. I'd say 26.Rxg7! +- is more Wednesday/Thursday level being a few less ply deep. |

| Nov-29-19 | | Olavi: Great Snake Variation? Good grief. |
|
| Nov-29-19 | | agb2002: Black threatens Bxe6 and Nxe6.
The first idea that comes to mind is 25.Re7 followed by Rxg7. It seems to work after 25... Qxc4 26.Rxg7 Rxg7 27.Re8 or 26... Kxg7 27.Re7+. However, I haven't found anything decisive after 25... Qg6. In any case I'd play 25.Re7. |

 | | PawnSac: < Carrots and Pizza: Is this a correct puzzle? Correct me please if I'm wrong, but this doesn't seem like a true tactical puzzle. > no you're not wrong. This was a positional sac puzzle. Strictly speaking, all positions are both tactical and positional, but the point is, the puzzle of the day doesn't have to be a tactical combination to win material. |
|
| Nov-29-19 | | Cheapo by the Dozen: Things really get complicated if Black chooses the ... Kxg7/... Kf6 defense. The engine thinks White has a thumping win, but it includes a number of non-forcing moves slowly tightening the noose. |
|
| Nov-30-19 | | patzer2: As <RV> observes 17...e4 = would have equalized for Black. However, early in the opening with the ugly 7...Nfd7?, Black's game had already taken a turn for the worse. After 7...Nfd7? 8. d3 ± (+0.84 @ 31 ply, Stockfish 10), White has an easy and comfortable advantage while Black struggles to finish development. Instead of moving the Knight twice in the opening and blocking the Bishop and Queenside development, Black does better with normal development via the popular move 7...Nc6 as in Black's win in Ivanchuk vs M Vachier-Lagrave, 2013. |
|
| Nov-30-19 | | patzer2: I wonder if White wasn't playing our recent Friday puzzle position solution 25. Re7! move by move without seeing all the tactics involved. I found 25. Re7 and would have followed with 26. Rxg7 simply because the even exchange of material after 26...Rxg7 27. Be5 ± trades material for a position in White's favor. Hopefully, I would have found the better move 27. Re8! +- as Black did in this game. One reason I think White might have been taking it a move at a time, without seeing all the tactics, is that on the follow-up 30. Qe5 +- (+3.05 @ 28 ply, Stockfish 10), White misses the much stronger 30. gxf4! +- (+11.37 @ 27 ply, Stockfish 10). |
