| Mar-17-14 | | Karpova: This was the 10th and last game of the New England Championship, December 1937. Morton won the game and the match (5:2:3). Nice ♕ sacrifice after 27.dxc6.

 | | al wazir: 27. dxc6 Rd1 28. Rxf7 Rxf1+ 29. Rxf1 was an obvious try. At that point white has ♖+♗+♗+♙ vs. ♕+♘, so it didn't cost white anything. After 29...d6, black's only defensive move, 30. Bd5+ is easy to find, and the rest just plays itself: 30...Kh8 31. c7 Qc8 32. Bxd6, with Rf8+ to follow. |

 | | An Englishman: Good Evening: Interesting to see players try and find their way in such a little known variation at the time; the database has fewer than 10 games with the position after 6.Bg2 before this one. |

 | | agb2002: White has the bishop pair for a bishop and a knight. The black rook protects the bishop. This suggests 27.dxc6: A) 27... Rd1 28.Rxf7
A.1) 28... Rxf1+ 29.Rxf1
A.1.a) 29... Nb6 30.c7 Qc8 (30... Qxc6 31.Rf8#). A.1.b) 29... Nd6 30.Bd5+ Kh8 (30... Nf7 31.Rxf3 wins) 31.c7 Qc8 32.Bxd6 wins. A.1.c) 29... g6 30.Rf8+ Qxf8 31.Bxf8 Kxf8 32.c7 Nb(d)6 33.Bh3 wins. A.2) 28... Ne3 29.Bxe3 Rxf1+ 30.Rxf1 + - [R+2B+P vs q], the white pieces while push the passed pawn to promotion. B) 27... Rc7 28.Bd5
B.1) 28... Bxd5 29.Rf8+ Qxf8 30.Qxf8#.
B.2) 28... Qxd5 29.Rxd5 wins.
B.3) 28... Nd6 29.Bxd6 Qxd6 30.Rxf7 wins. |

| May-08-20 | | scormus: W wins easily by force after 27 dxc6 Rd1. I was expecting ... Rc7 and Im still trying to find the win as I write. 28 Rxf7 Rxf7 perhaps? No. Ah, Now I see it :) |
|
| May-08-20 | | Brenin: This must be an easy week, as I'm on 5/5. The thought process was: material equal, why not take the loose pawn? Oh dear, 27 ... Rd1 wins White's Q. Hang on, 28 Rxf7 Rxf1+ 29 Rxf1 leaves White with R+B+P v Q, threats on f8, and a promotable P on c6. Check details (thanks <agb2002> for spelling them out), yes it works. |
|
| May-08-20 | | scormus: <Brenin> Easy week? No, it's just we're improving. And anyway, don't spoil our satisfaction. 5/5 is 5/5! |

 | | OhioChessFan: I tried 31. Bxc6 which is not quite as good as the game. |
|
May-08-20
 | | FSR: <OCF> It's also illegal. Presumably you meant 31.Bxd6. I wanted to play 30.Rd1, which looks crushing, albeit less incisive than the game continuation. |

| May-08-20 | | alshatranji: Interesting. I realized that the game continuation is the only way to make progress. But I didn't have a plan after 29. Rxf1. Of course, there is the prospect of advancing c6, but nothing seemed clear or certain. But now I see it, Bd5+, then after Kg8 or Kh7, there is the threat of Rf8. Well done. |

 | | thegoodanarchist: That's it - the zwischenzug!
It is one of the biggest factors separating great players from the rest of us. 28.Rxf7! is the zwischenzug I missed. |

 | | Jimfromprovidence: After 27 dxc6 Rd1 28 Rxf7 Rxf1+ 29 Rxf1 <agb2002> mentions a sequence <A.1.c) 29... g6 30.Rf8+ Qxf8 31.Bxf8 Kxf8 32.c7 Nb(d)6 33.Bh3 wins.> There is an interesting alternative which wins another piece for white here. Here is the position after 27 dxc6 Rd1 28 Rxf7 Rxf1+ 29 Rxf1 g6 30 Rf8+ Qxf8 31 Bxf8 Kxf8.

| | agb2002: <Jim> 31.Bd5+ is technically much better than my prosaic 31.Bxf8. |
|
| May-09-20 | | TheaN: I missed this yesterday and sadly I pressed the next move button one too many, so I spoiled this for myself. However, I do feel that it's a rather easy Friday. <27.dxc6!> Black's dealing with a lot of pressure suddenly. It's obvious Black wants to play Rd1 but that it probably doesn't get him anywhere, but there aren't too many alternatives. A different counterattack doesn't exist and the rook only has c7 and d2 to flee. After 27....Rd2? 28.Rxf7 +- is simple, but 27....Rc7 28.Bd5! is not too difficult either, where everything for Black is overworked. However, <27....Rd1 28.Rxf7 Rxf1+> else disaster <29.Rxf1> we end up here:

These are these kind of positions where it's so obvious the bishops dominate the queen, and the rook dominates the knight. Besides that, White threatens an immediate Bd5+, with Qxd5 Rf8#, and if Black defends against this immediately Rf8+ is also dangerous (far up passed pawn down). 29....Nd6 fails on another overwork 30.Bd5+ Kh8 31.c7! and Black collapses. 29....g6 is too slow (h6 is similar but actually gives no escape square to defend f8): 30.Rf8+ Qxf8 and even though 31.Bxf8 wins, better is 31.Bd5+! winning another tempo. Interestingly, the two variations both end up with different bishops. After 31....Qf7 the dark squared bishop forces queening as after 32.Bxf7+ Kxf7 33.c7 +- its defending both squares to prevent queening. If 31....Kg7 the light squared bishop wins the day after 32.Bxf8+ Kxf8 33.Bxc4 Ke7 (bxc4 34.c7) 34.Bxb5 +- and White can not yet queen the c-pawn, but can cruise to a win otherwise. |

| Sep-17-20 | | SeanAzarin: Now I'm thinking about the Roland Deschain series of books. Fantastic pun, BTW. |
|
| Sep-17-20 | | schnarre: ...Nice finish! |
|

 | | Honza Cervenka: Being white, after 24...Rc7 I would play simply 25.Bb4 with idea 25...Nb7 26.Bxc6. |
|
| Sep-17-20 | | shaileshnanal: It is a classic game explaining the power of Bishops firing at f8 & d5 and how back rank weakness can be exploited.For all the time Black's queen remained tied up to the defence of f8 square. |
|
| Sep-17-20 | | Brenin: Not much to add to comments made in May, save a brief salute to <offramp>, who drank the milk of Paradise today. |

| Sep-17-20 | | Ironmanth: Interesting game! Thanks, chessgames. Y'all stay safe out there, and play hard, play often, and play FAIR! :)) |
