| May-01-16 | | Howard: McCambridge's 16.f5 was not only a TN, but it also took first place in the Informant as the best TN for that volume. Now...I gotta figure out why that move was so impressive. |

|
| May-01-16 | | whiteshark: Thanks <perf>! So Eingorn has done his homework. Although I wonder about this speedy information transfer acrosss the Iron Curtain in the early 80ties ? |
|
May-02-16
| | perfidious: <whiteshark> One wonders whether Eingorn knew of the game, though, given that information travelled much more slowly back then; believe Jon Speelman wrote of this in his collection of games in the 1990s. |
|
| May-02-16 | | offramp: This is McCambridge's Mercedes. |
|
| May-02-16 | | Howard: Rather interesting how my nonchalant comment from just yesterday, has generated so much interest in this game ! At any rate, what "perfidious" is apparently saying is that Eingorn played McCambridge's surprising novelty, and he, too, scored a win--just a month after the McCambrige game ? Remind me to check the Informant when I get home this evening. |

| | patzer2: Based on <Rv>'s deep computer analysis, it would appear the positional 21. Re3 (+3.51/41) is as good or better than the flashy game tactic 21. Bxe5 (+2.20/41). One point of 21. Re3 is that 21...Rxg2?? drops the Rook to the Queen fork 22. Qd5+ . |
|
| Aug-07-16 | | Patriot: Time is of the essence—especially in Chess. This is why I started looking at a swift attack with disregard for material. The question is how can white take advantage and get the game rolling quickly? My first thought is 21.Bxe5 Qxe5: 22.Re3 Qa1+ 23.Kf2 Qxh1 24.Re8+ Kf7 25.Bh5+ …
25…Kf6 26.Qh6+ Rg6 27. Rf8+ Ke6 28.Qe3+ Kxd6 29.Rd8+ (29…Bd7 30.Qd3+ Ke6 31.Qxd7+ Kf6 32.Qd6+ Kg5 33.Bxg6 ) 29…Kf7 30.Qe7+ Kb8 31.Qe5+ Rd6 32.Qxd6# 25…Rg6 26.Bxg6+ hxg6 27.d7 looks winning.
Or…
22.Re3 Qf6 23.Re8+ Kf7 24.Bh5+ Rg6 25.d7 looks winning. |
|
| Aug-07-16 | | Patriot: I missed a few things here and there like ...Bd4+ (forgot about that useless bishop on h8). Apparently 25...Kf6 26.Qh6+ is a draw after 26...Rg6 27.Bxg6 Bg7. But 26.Rf8+ leads to mate. |

Okay, I (white) have a far-advanced passed Pd6 pawn that I can't advance right now. I also have a pin Pe5, and perhaps attacking this pin and opening the e-file can help with the Pd6. So my first thought was to put heat on black's Pe5 with <21.Re3>
click for larger view
I don't see anything black can do to help this pawn. He may try 21...Qh4+, but that doesn't really buy any time since 22.g3 blocks and attacks the Q. Black may try to avoid losing the exchange with <21...Rf7>, and then <22.Bxe5>
click for larger view
Black's queen is under attack and curiously short of places to hide! - 22...Qg6? 23.Rg3 pins Q+K
- 22...Qh6? 23.Rg3+ wins Q with discovered attack.
- 22...Qd1? 23.Rg3+ Bg7 24.Qd5 pins R with Bh5 threat to win it. I'm think black's best reply might be <21...Bd7>, which blocks the pawn and activates the Ra8, and then <22.Bxe5>

I've won a pawn, and now it looks like I win the exchange. I have a rook on the open e-file, and that Pe6 to make headaches for black. I'm feeling pretty good about this. ~~~~
Checking with computer, I see that 21.Re3 is just as good as 21.Bxe5. It's not as cute, but easier to find IMO. Also, I see that my followup (while winning) wasn't "best", but hey, finding a way to win a Sunday puzzle without having to actually go insane is good enough for me. :-) |

 | | agb2002: White is one pawn down.
The g-pawn is hanging although it's indirectly protected by Qd5+. There are a number of ideas in the position. For example, 21.Qd5+ Qf7 22.d7 Qxd5 23.dxc8=Q+ wins a piece but fails to 22... Bxd7. Or 21.Qd5+ Be6 22.Qxe5 Qxe5 23.Bxe5 Rxg2 24.Bg3 but Black has 24... Rxe2+ 25.Kxe2 Bxc4+. Another idea is 21.Re3, aiming at e5:
A) 21... Qg5 22.Bxe5
A.1) 22... Rg6 23.Bxh8 Kxh8 24.Re8+ Kg7 (24... Rg8 25.Qxg5 wins) 25.Qxg5 Rxg5 26.d7 wins. A.2) 22... Rd7 23.Bxh8 Kxh8 24.Re8+ Kg7 25.Qxg5+ wins. B) 21... Rd7 22.Rxe5
B.1) 22... Rxd6 23.Re8+ Kf7 24.Bh5+ wins decisive material. B.2) 22... Qxd6 23.Qxd6 Rxd6 24.Re8+ Kf7 25.Bh5+ Rg6 26.Rxh8 wins a rook. C) 21... Rg6 22.Rxe5
C.1) 22... Qxd6 23.Qxd6 transposes to B.2.
C.2) 22... Qh4+ 23.g3 Rxg3 24.Qd5+ Kf8 25.hxg3 wins decisive material. -----
I'm not sure but I'd play 21.Re3. |
|
| Aug-07-16 | | devere: 21.Re3! wins easily, so there is no good reason to risk the complications that follow 21.Bxe5. |

 | | drollere: black is up a p and perhaps has the edge in space, but white's pieces are more active. both sides have a passed pawn and immediate threats of check at Qd5+ and Qxc5 for white and Rxg2 and Qh4+ for black. white's Bxe5 is nasty, so possibly something to do with 21. Qd5+ Be6
22. Bxe5(p) Bxd5(Q)
23. Bxf6(Q) Rxg2(p)
24. Rg3+ Rxg3(R)
25. g3(R)
can suggest a better attack.
21. Qd5+ Be6 22. Qxc5 Rxg2 doesn't look happy.
i settled on:
21. Bxe5 Qxe5 (this won't end well)
22. Re3 Qe6 (i looked at Qa1+)
23. Rxe6 Bxe6
24. Qh6
which is wrong (Rg6) but stuck in my head because i'd rejected Rh3 and Qh6 as a way to penetrate the back rank. but i did get 3 moves deep on this one. hjartson made some great defensive moves in the endgame, a real slugfest from both sides. |
