 | | perfidious: Have to say that Commons fared rather better against the list provided by <Albertan> long ago than did I: Losses in all games, including Mednis (in a simultaneous), four against Bisguier and one each to Weinstein, Benko, Karklins and Browne. |

| Dec-11-16 | | Al2009: 28. Qxe8+? is a clearly useless sac and blunder. After 28. Bxf8! White wins immediately.
If a) 28...Rxc3 29. Rd1+ Kc7 30. Qf7+ 
b) 28...Qc7 29. Bh6! (30. Bg5+)
White entered into an endgame with a piece up, but he could immediately and simply win in 2-3 moves after 28. Bxf8! Useless Queen's sac!! |

 | | scormus: Very elegant combination starting 22 Bxg6+ (it would have ben embarrassing to not get that move) up until 27 Bxh6?! From there W seems to have muddled through and was able to win because the position was so overwhelming. So those who missed Bxh6 and Qxe8+ need not be disappointed. Better is 27 Bg5+!, a natural move which clears the d-file. 27 ... hxg6 28 Qf6+.
If .... Be7 then 29 Rd1+ is crushing
if .... Kf7 then 29 Qxe5+ is crushing |

Maybe its an early Xmas Gift :)

| Dec-11-16 | | Clodhopper: Well, I thought I had it solved - without even having seen the pun hint. But black's 23rd was different from either of the moves I considered - and the game went a different direction from there. A valuable lesson - always look for one more reply you hadn't considered before launching a sac. |
|
| Dec-11-16 | | Gregor Fenrir: <Al2009> after 28. ♗xf8? Black may play 28...♗c6. After 29.♖d1+ ♖d4 30.♖xd4+ exd4 31.e7+ ♔c7 32.♘e4 White has huge advantage (game might continue 32... ♔b7 33.♘d6+ ♔a7 34.♔g1 ♖xf8 35.exf8♕ ♕xf8 36.♕f7+ ♕xf7 37.♘xf7 d3 38.♔f2 ♗xg2 39.h4) but 28. ♕xe8+ is the best move. |
|
| Dec-11-16 | | RKnight: <Scormus> is right that 27. Bg5+! is a bigger crush than 27. Bxh6, but black could have improved on his earlier move, 26. Rxe5 Be2 prevents the crush, though black's position is far from enviable. |

 | | steinitzfan: Magnificent Chess -- and totally sound according to the computer. I tried 22Nd5 which fails but I credit myself with seeing that all ways to capture the knight lose. White starts with a material deficit so these difficult sacrificial lines are not optional. White had to see a lot. |
|
| Dec-11-16 | | Moszkowski012273: Yeah 27.Bxh6... was quite incorrect. On the other hand...the "useless queen sac" was 100 percent spot on <AL2009> |
|
| Dec-11-16 | | ChessHigherCat: I'm not a GM but I can recognize GM-level play and this is it. How many players would have resisted the temptation of 26. f5xNg6++ instead of playing f5xe6, for example? |
|
| Dec-11-16 | | agb2002: White has a pawn for a knight.
Black is probably considering Nf5.
White has f5, Bxg6+, Nd5, Ne4, exd6, etc. Black controls the square f5 with a knight and two pawns. This suggests 22.Bxg6+ Nxg6 (else 23.Bxe8+ wins) 23.f5: A) 23... Ngxe5 24.fxe6+ Ke7 25.Nd5+
A.1) 25... Bxd5 26.cxd5
A.1.a) 26... Nxg4 27.Rf7+ Kd8 28.Rxd7#.
A.1.b) 26... Nf6 27.Rxf6 Kxf6 (27... Nxg4 28.Rf7+ Rd8 29.Rd7#) 28.Rf1+ Nf3 29.Rxf3+ Ke7 30.Qh4#. A.2) 25... Kd8 26.exd7 (26.Rxf8 Rxf8 27.e7+ Ke8 28.exf8=Q+ Nxf8 unclear) 26... Bxd5 (26... Nxg4 27.dxe8=Q#) 27.dxe8=Q+ Kxe8 28.cxd5 wins decisive material (28... Nxg4 is illegal). B) 23... exf5 24.Qxf5+
B.1) 24... Ke7 25.exd6+
B.1.a) 25... Kxd6 26.Qxg6+ Kc7 27.Bf4+ wins.
B.1.b) 25... Kd8 26.Rxe8+ Kxe8 27.Qxg6+ Kd8 28.Rxf8+ Nxf8 29.Qf6+ Kd7 (29... Ke8 30.Qe7#) 30.Qe7+ Kc6 31.b5+ axb5 32.cxb5+ Kc5 33.d7+ seems to end up two pawns ahead at least. B.2) 24... Kg7(8) 25.Qf7+ Kh8 26.Qxg6
B.2.a) 26... Nxe5 27.Rxe5 Rxe5 28.Rf7 wins (28... Re1+ 29.Bxe1). B.2.b) 26... Re7 27.e6 Ne5 28.Qf6+ Kh7 (28... Kg8 29.Re3; 28... Bg7 29.Qxe7; 28... Rg7 29.Qxh6+) unclear. |

| Dec-11-16 | | RandomVisitor: Note that 18...h6 removed one of the two pawn defenders of g6. This allows the future Bxg6 to be effective. Other black move number 18 allow equality:

| Dec-12-16 | | Al2009: <Gregor Fenrir> Sorry, but your suggestions are not persuading, 28. Bxf8! is better than 28. Qxe8+?! and in addition I wouldn’t play at all as you suggested. After 28…Bc6 I would play
29. Qd3+! Rd4 30. e7+ Kc7 (30…Kd7 31. Qf5+ Kd6 [31…Kc7 31. Qxe5+ Rd6 32. Rd1 ] Re1! ) if 30…Kc8 31. Qxa6+ Qb7 32. Qe2! (followed by Nb5 and Rc1 )) 31. Qxa6! Qb7 ( 31…Rd2 32. Rc1! Bxg2+ 33.

Qxe5+ Why should White trade immediately Queens, when it is possible to win in another way? |

| Dec-12-16 | | patzer2: The first few move of yesterday's difficult Sunday puzzle (22. ?) seemed pretty obvious to me, with the demolition 22. Bxg6!+ Nxg6 23. f5! required to crack open the position and expose the Black King to attack. However, as is typically the case with our Sunday puzzles, I found the follow-up very difficult. Here's my look at the combination and a couple of side lines with the computer (Deep Fritz 15): <22. Bxg6+ Nxg6 23. f5 Ndxe5> 23...exf5 24. Rxf5+ Kg7 25. e6 Nde5 26. Rexe5 dxe5 27. Rf7+ Kh8 28. Qxg6 Bxg2+ 29. Kg1 Bc5+ 30. bxc5 Be4 31. Rh7#) 24. fxe6+ Ke7 25. Qxg6 Kd8 (25... Nxg6 26. Rf7+ Kd8 27. Rd7# <26. Rxe5 dxe5 27. Bxh6> Though this is winning, even stronger according to the computer is 27. Bg5+ hxg5 (27... Kc7 28. Rf7+ Be7 29. Bxe7 Bc6 30. Bd6+ Kxd6 31. Qd3+ Kxe6 32. Qg6#) 28. Qxg5+ Be7 29. Rd1+ Kc7 30.
Qxe5+ Kc6 31. Qd5+ Kc7 32. Qd7#.
<27... Rxc4 28. Qxe8+ Kxe8 29. Rxf8+ Ke7 30. Rxb8 Bc6 31. Nd1 b5 32. Kg1 Kxe6 33. Rb6> P.S.: As <Random Visitor>'s analysis with Komodo 10.1 indicates, Black could have improved and equalized earlier with 18...Nh5 = or 18...Bg7 =. After the slightly inaccurate 18...h6?!, White secured a lasting initiative with the initial demolition sacrifice 19. Nxf7!  to  . Black's decisive mistake appears to have been 20...Ng8?, allowing a second and decisive demolition sacrifice with 21. Qg4 Ne7 22. Bxg6! (+4.18 @ 20 depth, Deep Fritz 15). Instead, as <Random Visitor>'s analysis with Komodo 10.1 indicates, 20...dxe5 21. fxe5 Nxe5 22. Qxe5 Qxe5 23. Rxe5 Rcd8 24. Re3 would have given Black practical counter chances. |
|
| Feb-10-19 | | devere: 19.Nxf7 and 20.e5 look obvious. After that it depends on what Black does. Probably best for Black is to give back the piece and trade Queens on e5. Then White has a slightly better position, but Black should be able to hold the Queenless middle game. |
|
| Feb-10-19 | | lost in space: I like this mate (with a little help form Black): 19. Nxf7 Kxf7 20. e5 Ng8 21. Qg4 Ne7 22. Bxg6+ Nxg6 23. f5 Nde5 24. fxe6+ Ke7 25. Qxg6! Nxg6? 26. Rf7+ Kd8 27. Rd7# 
click for larger viewBy the way, I do not find a convincing way how to win after 20...dxe5. 21. fxe5 (found nothing better) Nxe5 22. Qxe5 Qxe5 23. Rxe5 and Black is better, but it is not enough to claim a win.

| Feb-10-19 | | ChessHigherCat: It's been a couple years since I've seen the game and I didn't remember the position but I came up with this: 19. Nxf7 Kxf7 20. e5 Ng8 21. Qg4 Ne7 22. f5 exf5 23. e6+ Kg8 24. Bxf5 Nxf5 25. Qxg6+ Ng7 26. Qf7+ Kh8 27. exd7 Rxe1 28. Rxe1 Rd8 29. Bxh6 Bc6 30. Bxg7+ Bxg7 31. Re7 Bxg2+ 32. Kg1 Rg8 33. Qh5+ Bh6 34. Qxh6# I don't know how much I subconsciously remembered. Anyway, I completely agree with my comment from a few years back (says CHC2 to CHC1), Commons plays like a real GM. There's a lot of discussion of that point on his home page. GM Commons, I salute you, fantastic game! |

| Feb-10-19 | | Walter Glattke: 25.Qxg6 Nxg6? 26.Rf7+ Kd8 27.Rd7#
Option: 20.-Bxg2+ 21.Kxg2 Qa8+ 22.Kg1 h5 23.exf6 Nxf6 +- |
|
| Feb-10-19 | | SpamIAm: I'm wondering if 12...g6 was a wasted move. It doesn't really prevent an eventual f5 by white and in any case he can respond to f5 with ...Ne5. |
|
| Feb-10-19 | | Walter Glattke: 27.Bxh6 Bxh6? 28.Rd1+ e.g.Kc7 29.Qf7+ Kc6 30.Qd7# Lasts longer with Bd2, Qd6, Re7. |

| Feb-10-19 | | BwanaVa: I remember this game for the quality but also for the circumstances. Commons went to Europe to play in 3 international tournaments in the Spring/Summer of 1976, scored great results, and rocketed to IM at a time when the US did not have a lot of titled players...and US Chess was in a chasm due (in part) to Fischer not defending in 1975. Commons results were-as they say-a tonic. RIP Kim Commons. |
