|Jul-12-18|| ||Penguincw: And my streak ends here, with the wrong bishop sac.|
In any case, this is why a knight on f3 is important. (albeit it just moved to d2 to recapture)
|Jul-12-18|| ||andrewjsacks: Lasker-Bauer in reverse.|
|Jul-12-18|| ||NM JRousselle: Very instructive.
The decisive mistake was the "automatic" recapture with the bishop on move 13. 13 Nc4 was box.
|Jul-12-18|| ||Cheapo by the Dozen: For once, I saw the two-bishop sacrifice, because White can straightforwardly close down either or both of Black's diagonals. But I stumbled a bit around 17 f3.|
|Jul-12-18|| ||Cheapo by the Dozen: To be clear: Bxe6+/d5 shuts down one diagonal, while f4 shuts down the other.|
|Jul-12-18|| ||ChessHigherCat: Ye old double bishop sacrifice:
13...Bxh2+ 14. Kxh2 Qh4+ 15. Kg1 Bxg2 16. Kxg2 (16. Bxe6+ Kh8 17. Kxg2 Qg4+ 18. Kh1) Rf6
Et adieux Charles...
|Jul-12-18|| ||jith1207: I was worried about 18.Ne4 in the game text. It sure leads to a complicated position, that requires a long drawn out win for black. Very difficult for me to predict how to proceed, even as the initial moves are telling.|
|Jul-12-18|| ||ChessHigherCat: Akh khakh, I missed the 17. f3 defense, and if I had seen it, I think I probably would have screwed up by playing 17...Qg3 which allows the 18. Ne4 "in the game text" hallucinated by <Jith1207>'s buggy software (sorry, couldn't resist after your jibe at <ChrisOwen> the other day).|
BTW, treasure hunt challenge for the bright kids who thinks he uses software: cite some software that produces output anything remotely similar to his style from normal speech (while actually taking the trouble to compare the texts).
|Jul-12-18|| ||landshark: I missed 17...Bh3, opting fort Rf6 instead. I still think it wins - maybe not as quickly as the gamer move?|
|Jul-12-18|| ||agb2002: White threatens Bxe6+.
The position reminds me of Lasker-Bauer and Nimzowitsch-Tarrasch. Therefore, 13... Bxh2+:
A) 14.Kxh2 Qh5+ 15.Kg1 Bxg2
A.1) 16.Kxg2 Qg4+ 17.Kh1(2) Rf6 wins.
A.2) 16.f3 Rf6 (16... Qg3 17.Ne4 fxe4 18.Qxg2 + -)
A.2.a) 17.Kxg2 Rg6#.
A.2.b) 17.Bxe6+ Rxe6 18.Qxf5 Bh3 and the double threat Bxf5 and Rg6+ wins.
A.3) 16.f4 Qg3
A.3.a) 17.Ne4 Bxe4+ 18.Qg2 Qxg2#.
A.3.b) 17.Rfe1 Bh3+ 18.Kh1 Qg2#.
A.4) 16.Bxe6+ Kh8 17.f3 Bh3
A.4.a) 18.Bxd7 (or 18.d5) 18... Qg3+ 19.Qg2#.
A.4.b) 18.Nc4 Rf6
A.4.b.i) 19.Rf2 Rg6+ wins (20.Kh1 Bg2+ 21.Kg1 Qh1#).
A.4.b.ii) 19.Bxd7 Rg6+ 20.Kh1(2) Bxf1#.
A.4.b.iii) 19.Ne5 Nxe5 20.dxe5 Rg6+ wins.
B) 14.Kh1 Qh5
B.1) 15.Bxe6+ Kh1
B.1.a) 16.Bxf5 Bg3+ 17.Bh3 (17.Kg1 Qh2#) 17... Qxh3+ 18.Kg1 Qh2#.
B.1.b) 16.Rfe1 Bg3+ 17.Kg1 Qh2+ 18.Kf1 Qxg2+ 19.Ke2 Qxf2+ 20.Kd3 Be4+ 21.Nxe4 (else 21... Bxc2 wins) 21... fxe4+ 22.Kc3 Qxc2+ 23.Kxc2 Bxe1 wins decisive material (24.Rxe1 Nf6 - + [r+n+2p vs 2B]; 24.Bxd7 Bf2 25.Bc6 Rad8 26.Kd2 Rf3 - + [r+n+2p vs 2B]).
B.2) 15.f3(4) Bg3+ 16.Kg1 Qh2#.
B.3) 15.Rfe1 Bg3+ as in B.1.b.
|Jul-12-18|| ||FSR: White is rated around 2400 FIDE. Allowing the two-bishop sacrifice seems very naive. Maybe he thought 17.f3 would save him.|
|Jul-12-18|| ||AlicesKnight: Nice example of the double-bishop sacrifice to blow up a castled position. Saw it OK. White's 'spite attack' is easily ignored. See Lasker vs J Bauer, 1889 and Alekhine vs J Drewitt, 1923 among others.|
|Jul-12-18|| ||Walter Glattke: I had played 13.-Bxh2+ 14.Kxh2 Qh4+ 15.Kg1 C) with 15.-Rf6 16.f3 Qg3 17.Bxe6+ Rxe6 18.Qxf5 Rg6 19.Rf2! but
there is no clear win way. A4c) 16.Bxe6+ Kh8 17.Bxf5 Bxf1 18.Nxf1 Qg5+ 19.Ng3, maybe, 15.Bxg2 is wrong, after 15.Bxe6 there are several possibilities.|
|Jul-12-18|| ||Mayankk: Got the first 3 moves in right order, first Bishop sac on h2 to get our Queen on h file with a tempo and attempt to sac another Bishop at g2 again. Note that Kxg2 runs into Qg4+ followed by a Rook lift which is pretty hopeless for White.|
I didnít anticipate the f3 defence and I wouldnít have found the Bh3 line, diverging with the simpler 17... Qg3 idea unfortunately.
|Jul-12-18|| ||jith1207: <CHC>: no problem, you just described my mind perfectly, with the analogy of a buggy software.|
|Jul-12-18|| ||ChessHigherCat: <Mayankk> Here's the refutation of 17...Qg3, which you have to be a computer to see:|
1) +5.54 (23 ply) 17...Qg3 18.Ne4 Qg6 19.Bxf5 Rxf5 20.Qxg2 Qxg2+ 21.Kxg2 a5 22.Rc1 c5 23.dxc5 Nxc5 24.Nxc5 bxc5 25.Rfd1 Rg5+ 26.Kf2 Rh5 27.Kg3 Rg5+ 28.Kf4 Rg2 29.Be5 a4 30.Rd7 axb3 31.axb3 h6 32.e4 Ra3 33.Rb7 Kh7 34.Rxc5
|Jul-12-18|| ||cocker: 18 Ne4, as suggested by <jith1207>, would have been a much better try.|
|Jul-12-18|| ||PJs Studio: Chess is pattern recognition. I figured this problem out in about three seconds... only because Iíve seen Nimzowitsch v Tarrasch. Iíve been playing terribly of late and wouldnít have figuted this problem out. |
Is that all it takes? Having seen it all in previous study?
Nimzowitsch vs Tarrasch, 1914
|Jul-12-18|| ||stacase: Way too easy for a Thursday.|
|Jul-12-18|| ||takchess: Streak ends here. I thought bh7+ followed by Qh5+ followed by Rook lift With a bishop sac if needed on the f3 square if the knight moved there. Wonder if there was a tactic for white here if they were on move.Nice Potd.|
|Jul-12-18|| ||Mayankk: Thanks CHC.
Black seems to have gotten into an almost perfect French defence position by move 10 - a strong knight on e4 which canít be taken without giving the kingside Rook an open file as well as making the knight on f3 duck for cover. And there is no way to deny the Bishop a piece of action without taking the e4 knight. And the other Bishop and Queen are just waiting in the wings as well.
|Jul-12-18|| ||saturn2: I went for the first 3 game moves and reckoned queen and rook would finish off the white king. I also saw the in between manouvre Bxe6+ d5 does not help white.|
|Jul-12-18|| ||Richard Taylor: A la Tarrasch. Strip away the K side. And then finish White off...|
|Jul-12-18|| ||malt: I had 13...B:h2+ 14.K:h2
(14.Kh1 Qh4 )14...Qh4+ 15.Kg1 Rf6 16.d5 Rh6
Missed the; Ye old double bishop sacrifice: <CHC>
|Jul-12-18|| ||patzer2: Early in the opening, I prefer the popular moves 3. d4, 3. Nf6 or 3. g3 over the rarely played 3. e3.|
Our Opening Explorer records 3. e3 only haven been played three times, with the result being two wins for Black and one win for White.
Perhaps the reason 3. e3 is so unpopular is because it gives White no advantage or initiative, as it allows Black to immediately equalize with 3...Bb7=, 3...d5 = or 3...Nf6=.
