 | | tpstar: Black to Play and Win after 30. Rd1.
White hoped to exploit the Kingside dark squares yet Black put a stop to that. |

 | | Phony Benoni: Black's up an exchange, but 32.Bh6 is a huge threat for. Loos like it's gonna be a back rank thingie, and the old trick of using the queen to lure the rook away comes to mind. But after the normal idea 31...Qd3 the rook just refuses to be tempted. Ah ha! It's <31. ..Qd5>, with the back rank idea and a double attack on the bishop. |
|
| Nov-29-16 | | BxChess: Interestingly, instead of the game line, I looked at 29...Rg4. Although one reply 30 Bh6 looks like what I call scissors mate for white, in fact it appears that in this case it is black who has an unstoppable mate beginning with 30...Qe4+. |

 | | An Englishman: Good Evening: 8.g4 appears to be Cori Tello's invention. Hypothesis--White wanted to test an opening innovation against literally world-class competition. Whilst applauding the courage, and recognizing the resemblance to the Stoltz-Shabalov Gambit in the Slav Defense, the variation has not yet enjoyed success, according to the database; a later game (K Haznedaroglu vs Dreev, 2016) also ended in a Black victory. |
|
| Nov-29-16 | | patzer2: Because of White's weak back rank, 31...Qd5  creates a decisive double attack threat.For a Black improvement, <An Englishman> is probably correct in condemning 8. g4?! which allows 8...h6  (-0.47 @ 26 depth, Komodo 10). Instead, 8. 0-0 = is objectively better.
According to the Opening Explorer, 6. b3 = as in Mamedyarov vs S B Hansen, 2015 has been better for White than the game move 6. cxd5 =. |
|
| Nov-29-16 | | saturn2: ..Qd5 and white cannot defend both B and R in one move. |
|
| Nov-29-16 | | Cheapo by the Dozen: I love Tuesdays!
31 ... Qd5, an attempt at diverting White's rook from the back rank, wins because it's a fork. The queen of course is poisoned because of the back rank mate. |
|
| Nov-29-16 | | agb2002: Black has a rook for a bishop.
White threatens Bh6.
The rook on d1 and the bishop are defenseless and White's back rank is weak. Hence, 31... Qd5: A) 32.Rxd5 Rg1+ 33.Rd1 Rxd1#.
B) 32.Bd2 Qxd2 wins the bishop (33.Rxd2 Rg1+ and mate next). C) 32.Rb(c,e,f)1 Qxg5 - + [R]. |
|
| Nov-29-16 | | drleper: <Ulhumbrus: However 8...h6?! disturbs the king side pawns and provides it with a target.> What would you suggest instead? 8...h6 looks like a good move to me (it's the top choice for engines too). White wants to gain space on the kingside with g5, so why allow that to happen? White is already signalling an intention to castle long, so black restrains white's kingside expansion and prepares for play against O-O-O. |
|
| Nov-29-16 | | mel gibson: The white King is trapped behind his own pawns - awful. |
|
| Nov-29-16 | | thegoodanarchist: Tello's position was Jello |
|
| Nov-29-16 | | AlicesKnight: It looks as if .....Qd5 wins at least the bishop. If R capture, the Black R executes mate in 3; if not, the white B goes. - Yup, that was it. |
|
| Nov-29-16 | | cocker: The combination started a move earlier. |
|
| Nov-29-16 | | Once: I liked <agb2002>'s spot of 32. Bd2
click for larger viewAt first glance, this looks like it defends against both threats - the bishop capture and the back rank mate. But 32...Qxd2 is a nasty shock. The bishop dies anyway because the back rank mate threat hasn't gone away. Fritzie also finds the delightfully sadistic 32...Rd8, 32...Rd4, 32...Re8 and even 32... b4 - all of which win handily. There is something a bit Cruella de Vil about 32...Rd8 
click for larger viewBlack plays this move then sits back in his chair with a big beaming smile waiting for the handshake. |
|
| Nov-29-16 | | zb2cr: 31. ... Qd5 does it. The Bishop and Rook are both threatened, and the weakness of White's back rank makes capturing the Queen with the Rook impossible. |
|
| Nov-29-16 | | PizzatheHut: If anyone else is curious as to why 18. Nxd4 isn't playable, here's why. I had to play around with the engine to figure it out. If <18. Nxd4, then 18...b4 19. Ne2 (or really any knight move) Be4> and the queen is lost. Black already had a large advantage at this point, because the tactics favor him tremendously. |
|
Nov-29-16
 | | Bubo bubo: Black exploits White's weak back rank with 31...Qd5. The queen is immune thanks to Rg1+ and mate, so the fork will win the Bg5, also removing any possible white mate threat. |
|
Nov-29-16
 | | gawain: For a Tuesday, this required a lot of thought. The key was to realize that Black does not have to force a quick mate but can use the threat of the back row mate to gain the winning advantage--in this case, to win a piece. |
|
| Nov-29-16 | | kevin86: White can capture the queen and get mated. |
|
| Nov-29-16 | | johngalt5579: looks like Qd5 attacking r and b and mate should do it. |
|
| Nov-29-16 | | dfcx: took a bit longer for today's easy puzzle.
White's weak back rank is defended only by the rook, 31...Qd5 deflects and forks in one move. |
|
| Nov-29-16 | | whiteshark: <31...Qd5!>, and that's it. |
|
| Nov-30-16 | | paavoh: @An Englishman: <the variation has not yet enjoyed success, according to the database> Perhaps it was being tested against too strong opponents (Kramnik, Dreev)? Might work at club level though. |
|
| Nov-30-16 | | R4f43l L3 M4550n: Very Beautiful game!
Interesting puzzle too (31... ?). |
