| Oct-20-19 | | Cheapo by the Dozen: Yet another poorly designed puzzle. It's pretty easy to solve up to the point of recognizing that White's e-pawn is poisoned, but per the engine White doesn't have a huge advantage yet at that stage. |
|
| Oct-20-19 | | The17thPawn: <al wazir> - Agree with your assessment. This game could have taken any of a myriad of directions. After the initial exchanges nothing is forced and black could have posed many more problems. I guess CG is in spoiler mode again. |

| Oct-20-19 | | mel gibson: I thought 17. b-d3
but Stockfish 10 says that's a draw.
Stockfish 10 goes with the actual game and says: 17. dxe5

|
| Oct-20-19 | | Matloc: I like this puzzle. Better save the queen or throw her away for: a rock; a black bishop; two opened columns dominated by own rocks; great diagonal by own black bishop; one step to dominate the other great diagonal; opponent's last row poorly defended? Deal! I'm not sure if an engine might evalutate properly such a situation. Volkov surely does! |
|
| Oct-20-19 | | 1stboard: I wonder if Mr. Volkov saw ahead from White's move 16 exd4 that 16 moves later would result in an unusual Queen trap ?? I sure did not. But saw the first move but certainly not the continuation nor would I have played 16 exd4 |

 | | agb2002: White has an extra pawn.
Black threatens B(N,R)xd4.
The first idea that comes to mind is 17.dxe5 Rxd1 18.Rfxd1: A) 18... Nxe5 19.Bxe5 Qxe5 20.Rd8+ Ne8 21.Rdxc8 Rxc8 22.Rxc8 with rook, bishop and knight for the queen. B) 18... Ng4 19.b5 Ncxe5 20.h3 Nf6 21.Bxe5 Qxe5 22.Rd8+ as above. C) 18... Ne8 19.f4 with the better game.
D) 18... Nd7 19.Re1 again with the better game (19... Ncxe5 20.f4). |
|
| Oct-20-19 | | alshatranji: So 17. dxe5 is basically the first idea that comes tom mind. However, I had Rxd1 18. exf6 Rxf1+ 19. Bxf1 gxf6 20. Nh5, with what seemed like a good attack, which now doesn't look that forcing. Instead, I should have planned with the foresight and confidence of a grandmaster: After 18.Rfxd1 Ne8, followed by 19.b5 Nd8, the material difference is not that huge, and White's far superior development and control should win, bearing in mind, of course, that then a new chapter of the game begins; you can't see clear results any time soon. The amateur demands immediate outcomes. If you make any material sacrifice, you want to get something back quickly, or else you start feeling the pressure; you think the game is slipping away. Of course, all this seems crystal clear now in retrospect. |
|
| Oct-20-19 | | King.Arthur.Brazil: I guess that in view of difficulty INSANE, many found the first moves: 16.fxe5 ♖xd1 17.♖fxd1 however the game went on and no ordinary combination, nor checkmate intentions, nor pin was present. Then what? I was more one searching what could be done. White improves his position, putting the enemy's ♘ out the game (i.e. in the 8th line) while two ♙ in b5 and e5 remove the acess of the black ♕, which turned out to be chased until the end. Inespected end. |
|
| Oct-20-19 | | TheBish: 31. Rh1! might make a good Tuesday puzzle. |
|
| Oct-20-19 | | drollere: after d:e5 the black Q turns out to be in jeopardy in many different lines. it's quite complex. |

| Oct-22-19 | | patzer2: The Sunday Oct 20, 2019 puzzle solution 16. fxe5 Rxd1 17. Rfxd1 ± (+0.99 @ 31 ply, Stockfish 10) illustrates that the exchange of a Queen for a Rook, Knight and Pawn is not always an even trade. In this case, White's extra Rook, Knight and Pawn are worth more than Black's Queen. |
|
| Oct-22-19 | | patzer2: Correction: The Sunday Oct 20, 2019 puzzle solution 17. dxe5! Rxd1 18. Rfxd1 Ne8 (forced) 19. Nc5! ¡À (+1.36 @ 38 ply, Stockfish 10) illustrates that the exchange of a Queen for a Rook, Knight and Pawn is not always an even trade. In this case, White's extra Rook, Knight and Pawn are worth significantly more than Black's Queen. |
|
| Oct-22-19 | | patzer2: The move 17. dxe5! may not be a forced win, but it is the strongest and clearly best move because the alternatives are weaker. The suggestion 17. dxe5! Rxd1 18. Rfxd1 is unsound because of the possibility 18...Nxe5? is not true. If 18...Nxe5?, White wins a piece and gains a decisive advantage with 19. Bxe5 +- (+3.53 @ 38 ply, Stockfish 10) as indicated in <agb2002>'s analysis. Indeed, 18...Ne8 is practically forced as the next best alternatives, 18...Nd7 19. Nf5 ± to +- (+1.81 @ 37 ply, Stockfish 10) and 18...Ng4 19. b4 ± to +- (+2.41 @ 36 ply, Stockfish 10), give White a near decisive advantage. After 18...Ne8, White's best is not the game continuation 19. b4 Nd8 ⩲ (+0.53 @ 38 ply, Stockfish 10). Instead, White secures a bigger, more clear advantage with 19. Nc5! ± to +- (+1.34 @ 40 ply, Stockfish 10). P.S.: After 19. b4 Nd8 (forced) 20. Nc5 Ne6 ⩲ to =, Black has a near level game. The decisive error comes later with 24...Qg4? 24. h4! +- (+2.06 @ 31 ply, Stockfish 10). Instead, 24...Bxf5 25. Nxf5 Qe6 ⩲ to = (0.00 @ 35 ply, Stockfish 10) gives Black level chances. |

| Oct-27-19 | | drollere: i've never seen this game before. |
|
| Oct-27-19 | | JimmyRockHound: Same puzzle as last Sunday? |
|
| Oct-27-19 | | stacase: I figured that it was 17.dxe5 followed by 17 Black x Queen but really we're supposed see that 15 moves later White regains the Queen sacrifice? Well OK it IS the Sunday puzzle which IS labeled "INSANE" |
|
| Oct-27-19 | | Walter Glattke: The same procedure as EVRY Sunday, a dinner for one! |

|
| Oct-27-19 | | WorstPlayerEver: Dunno, 17. dxe5 Rxd1 18. Rfxd1 Ne8 19. Nc5 Nxe5 seems to lead to a draw:
click for larger viewEventually White ends up with a pawn more, but I don't think it's sufficient. |
|
| Oct-27-19 | | WorstPlayerEver: 19. Nc5 Nxe5 20. Re1 Ng6
click for larger viewSF suggests 21. Bg4, I had 21. Bb5
In both cases White ends up with a pawn more.
21. Bg4 Be6 22. Nxe6 fxe6 23. Bxe6+ Kh8 24. Nh5 Qf8 25. Bb3 Nf4 26. Rxe8 Rxe8 27. Bxg7+ Qxg7 28. Nxg7 #dia2 
click for larger viewIf Black takes the Knight, then Rc7+ and h4 follow and Black is lost. So 21. Bg4 Bxg4 22. Rxe7 Nxe7 23. Nxb7 Rb8 24. Nc5 a5 25. f3 Bc8 26. Be5 Rb5 27. bxa5 Rxa5 28. a4 f6 29. Bf4 #dia3

| Oct-27-19 | | WorstPlayerEver: PS hmm.. I put the line in my desktop and it instantly came up with: 19. Nc5 Nxe5 20. Bxe5 Qxe5 21. Rd8 b6 22. Bf3 Bb7 23. Nxb7 Rxd8 24. Nxd8
