| Dec-20-10 | | Everett: 21.Nxe6 exposes the k-side light squared weakness. 23.d5 gains time for the queen to fully enter the attack. |

 | | chrisfalter: Suba annotates this game in his entertaining and instructive game collection, Dynamic Chess Strategy. In his book, however, the position after black's 7th move is reached through the Semi-Tarrasch rather than the Caro-Kann Panov Attack. |

 | | perfidious: <chrisfalter> So it is-whilst my copy of that excellent book is buried somewhere, I'll submit a copy of the correct score through White's tenth move. Curious how this version got here; Suba is not an e4 player and Farago mostly plays the French against 1.e4. In any event, the position reached after White's tenth is a QGD Semi-Tarrasch by transposition. |

| Feb-13-20 | | Cheapo by the Dozen: Weak puzzle. The first two moves are obviously right to play, because the worst-case outcome is three pawns for the piece plus a blistering attack. There's no need to actually see ahead to 23 d5 when the simpler 23 Rxg6+ wins so thumpingly. |
|
| Feb-13-20 | | Cheapo by the Dozen: Worse, the engine thinks 23 Rxg6+ was actually the best move. |
|
| Feb-13-20 | | Cheapo by the Dozen: To be clear, what's going on here is:
23 Nxe6+ fxe6 (utterly forced)
24 Rxe6
White now has two pawns in hand for the knight. The g6 pawn can't be defended, and if Black pushes it the h6 pawn is lost with check (and in that line White turns out to win the Black queen shortly thereafter). In all these lines White has three pieces bearing down on Black's king, with the fourth available to enter with check if Black's king tries to escape across the e-file. |

| Feb-13-20 | | Whitehat1963: Not even close. |

| Feb-13-20 | | malt: Have posted 23.N:e6+ should be 21.N:e6+ |

| Feb-13-20 | | Nosnibor: Does not 23...Nd8 hold out longer for Black? |

| Feb-13-20 | | TheaN: This one took me a while, as there are a few ideas for White. Qxh6+ and White has too few pieces to mate Black. Rxe6 allows Black the nasty hxg5 zwischenzug. Realizing it's likely a knight move, it leaves <21.Nxe6+>. Due to the fork, <21....fxe6 22.Rxe6> is forced. Interestingly, Black has only one proper way to defend g6. After 22....g5 Black exposes h6 23.Qxh6+ with a fast mate. The knight can be taken on both squares (22....Ne7 23.Rxe7+ +-, Ne5 23.dxe5 +-) and so can the rook (22....Rf6 23.Qxf6+). If Black ignores the threat on g6 White has four (Ra1 will join swiftly) raging pieces in a mating attack whilst a piece down for three pawns. I haven't calculated all of that out, but I'm convinced Black can't hold. So that leaves <22....Qf7>. Critical variation as Black pretty much forces a Q v RBN position, sadly after <23.Rxg6+ Qxg6 24.Bxg6 Kxg6 25.Qg4+ +-> Black's exposed king and knight (after a timely d5) never give Black the opportunity to regroup. Ra1 will join the queen, and White wins. |

 | | agb2002: Black threatens hxg5.
The position of Black's royal family invites to consider 21.Nxe6+ fxe6 22.Rxe6 Qf7 (only defense of g6) 23.d5 (to soften e7; 23.Rxg6+ Qxg6 -23... Kh8 24.Qxh6+ Qh7 25.Rg8+ and 26.Qxh7#- 24.Bxg6 Kxg6 25.Qg4+ Kf6 and White cannot capture the defenseless bishop): A) 23... Na5 24.Qg3 (24.Re7 Bxd5 25.Rxf7+ Bxf7 26.Qd4+ also seems to win but Black can probably put up more resistance) A.1) 24... g5 25.Qe5+ Kg6 26.Rg6+ Kh7 27.Rg7+ Kh8 28.Rh7+ Kg8 29.Q(R)h8#. A.2) 24... Kh8 25.Rxg6 Qf4 (due to Rxh6+) 26.Rg8+ Rxg8 27.Qxf4 wins decisive material (27... Bxd5 28.Qe5+). B) 23... Rce8 24.Rxg6+ Qxg6 25.Bxg6 Kxg6 26.dxc6 wins decisive material. |

| Feb-13-20 | | Lorenzo69: How about 21.Rxe6 fxe6 22. Nxe6+… |
|
| Feb-13-20 | | newzild: <Lorenzo69>
That is the most obvious first move, but Black does not have to capture the rook. He can play 21...hxg5. |
