| | offramp: Moves like 5.h3, and black's pretty poor game all round, make the game look like an everyday club game, not a game between players who are both over 2400. |
|
| Apr-19-06 | | hitman84: <offramp>5.h3 was a prophylaxy stopping Ng4 white's idea is to push e5 for Nf6 so h3 stops Ng4. I was there watching this game and Himanshu had already made his IM norm(final) and was looking rusty.. I agree he totally mishandled the opening.
A brilliant game by chanda! |

In your line, Black has alternatives such as 22...f6, 22...Ke8, 22...Ke6 and 24...c4. The line I saw was 21...Ke7 22. Qe4+
a) 22...Kf6 23. g5#
b) 22...Kd6 23. Bf4#
c) 22...Kd8 23. Bg5+ f6 24. Bxf6#
d) 22...Qe4 23. Qxe4+ Kd8 24. Bg5+ f6 25. Bxf6# |

 | | al wazir: I got the first move, but that's all.
After 15...Kd8, I think 16. Bg5 also wins: 16...Re8 (16...Bxg5 17. Qxg5+ f6 18. Qxf6#; 16...d6 17. Rxe7 Qxe7 18. Qxd6+ Bd7 19. Qxd7#) 17. Qxf7 b5 18. Bxe7+ Rxe7 19. Qxe7# |

| Nov-26-17 | | patzer2: Because it was a Sunday puzzle, where exchange sacrifices are common place, I figured the initial moves in our solution were 14. Rxe7! Bxe7 15. Re1 Kd8 16. Rxe7! Kxe7 17. Qe4+ +- with a difficult King hunt. After 17...Kf6 I went for 18. Qh4+ +-, which is the computer first choice. However, I did not see the only winning follow-up after 18. Qh4+ Ke6 (diagram below). 
click for larger viewHere (diagram above) the winning move I missed was 19. Bg7! +- (mate-in-eight, Stockfish 8). Unfortunately for me, other moves either draw or lose. The game continuation 18. g4! +- (+ 16.74 @ 33 ply, Stockfish 8) with the threat 19. g5# wins a bit more simply. The only way to avoid a quick mate is with 19...Qe5 when 20. Bg7+ Kxg7 21. Qxe5+ Kg8 22. Bb3 +- (+17.74 @ 35 ply, Stockfish 8) wins with ease. P.S.: Black's game takes a serious turn for the worse with the ugly 11...Bb6? allowing the game continuation 12. Bh6 ± to +- (+1.53 @ 31 ply, Stockfish 8) or the computer suggestion 12. Bg5 0-0 13. Bxe7 ± to +- (+1.81 @ 30 ply, Stockfish 8). Instead, the computer suggestion 11...f6 = to ⩲ (+0.24 @ 30 ply) keeps Black in the fight with near level chances. For an earlier improvement in this rare Sicilian opening line, perhaps Black should ditch the non-developing 7...Qc7 allowing 8. Nc3 ⩲ (+0.35 @ 32 ply, Stockfish 8) in favor of simple active development with 7...0-0 = (+0.08 @ 30 ply, Stockfish 8). |

then hit on 14.Rad1 which did bear fruit
but did not see the killer punch |

Very nice combination

| Nov-26-17 | | Pawn Slayer: Well, if black is a grandmaster, I'll eat my hat. His handling of the opening is clueless, and beautifully exploited by white. As Fischer used to say "the attack almost plays itself". 11 ..Bd6 is horrible - the sort of move a beginner would make. |
|
| Nov-26-17 | | njchess: Nice double rook sack. I got the initial sequence of 14. Rxe7+ Bxe7 15. Re1 ... It then took me a while to find Rxe7! I only found it because it occurred to me that since Black's queen was the only piece that could block the e-file and it was restricted to Black squares, which had no support, White could then play Qe4 with complete impunity. Black does mishandle the opening as early as 5. ... Nf6, better would have been d6 followed by Nf6. That way the knight has somewhere to retreat. It also gives his bishop some options. Follow Nf6 with 0-0. Instead, he tries to mix it up in the middle without first securing his king. Still, a nice attack by White. |

P.S.: Got distracted after the excitement of watching my oldest Grandson's California state high school championship football game on a Facebook video broadcast, and messed up the move numbers and letters. My Grandson's team won their game 42 to 20, and my Grandson scored two touch downs on offense and special teams and had two key interceptions on defense. For US college football fans it has been an exciting week of upsets with number one Alabama losing to Auburn and number two Miami losing to Pitt.
With a lot of help from turnovers and mistakes by Florida, my alma mater Florida State won their game which was a lot closer than the 38-22 score reflected. |

| Nov-26-17 | | Patriot: The stars seemed to line up for this sacrifice that I may have actually played this in a game if presented this position as white. |

| Nov-26-17 | | Pawn Slayer: @patzer2
"Grandson scored two touch downs on offense"
Just as a matter of interest, why do they call it a "touch down" when they don't actually touch the ball down? In a proper game (rugby) you actually have to get the ball down on the ground to score. American football is the least exciting and most incomprehensible game I've ever seen. |
|
| Nov-26-17 | | NBZ: <Patriot> Same here. I think though what I'd find difficult in a game is to set up the double-rook sacrifice with the initial pawn sacrifice 8. Nc3!. It takes a keen positional sense and good calculation to realize that the sacrifice is good. In the game line 11. Qd5 Bd6 12. Bh6 there is clearly great compensation for White, but he also must foresee 11. ... Bg7 12. Rxe7+! (without this resource, Black can play e6 and O-O). |
|
| Nov-26-17 | | Patriot: <NBZ> 8.Nc3 is a nice move that helps white develop more pieces after 8...Nxc3 9.dxc3 - 9.bxc3 to capture toward the center is the "general principle" but 9.dxc3 makes more sense here for development. Going after the pawn before castling wasted precious time for black. |
|
| Nov-27-17 | | patzer2: <Pawn Slayer> <Just as a matter of interest, why do they call it a "touch down" when they don't actually touch the ball down?> According to https://en.wikipedia.org/wiki/Touch... the original American Football rules, adopted around 1876, did require the ball to be "touched down" to score. By 1889 the requirement to actually "touch the ball down" (as in Rugby) was eliminated. However, the term "touchdown" to reflect a scoring play worth six points has remained in effect. |

| Mar-07-21 | | Gaito: Look at the following position:

White played 18.g4 and won quickly. Many kibitzers have even attached an exclamation mark to the move 18.g4.
However, both engines Stockfish 13 and LcZero immediately announce that White had a forced checkmate in 10 moves after 18.Qh4+.
It would be interesting to see how that mate is unfolded, since no human could possibly see such a forced mate at a glance, as computers do. Let us see:
18.Qh4+ and then:
A) 18...Ke6 19.Bg7 b5 20.Qe4+ Kd6 21.Bh6 (Δ 22.Bf4#) c4 22.Bf4+ Kc5 23.Qd4+ Kc6 24.Qxc4+! Kb7 25.Qxb7+ Ka8 26.Qxb8#. B) 18...Kf5 19. Bb3 c4 20.Qe7! Qe5 21.Qxf7+ Qf6 22.Qxc4 g5 23.Qd3+ Ke5 24.Qd5+ Kf4 25.g3#. C) 18...Ke5 19.Qe7+! Kd5 20.c4+ Kd4 (20...Kxc4 21.Qe4#) 21.Be3+ Kxc4 22.Qe4#
