 | | Phony Benoni: Rooks belong behind passed pawns, whether your own or your opponent's. So just knock out White's rook, and install black's/ |
 |
| Feb-13-18 | | saturn2: White has the threat Qf7.
34..QxRf4 35 QxQ Rf8 and black will remain with more material. |
|

 | | FSR: Ditto. |
|
| Feb-13-18 | | stst: Black is forced to take R, else Qf7 will mate.
34........ QxR
35.QxQ Rf8 and Q has to leave the f-file....IF
36.QxR KxQ and Black's f-P promotes (and will win easily) without any problem at all.
IF of course, Q leaves the f-file, Black's f-P promotes, same result. |

 | | agb2002: Black has an exta pawn.
White threatens Qf7+.
The white rook controls the promotion square. Therefore, 34... Qxf4+ 35.Qxf4 Rf8 and Black ends up a rook ahead at least (36.Qxf8+ Kxf8 and the white king can prevent f1=Q). |

 | | patzer2: My first thought in evaluating today's Tuesday (34...?) puzzle was that White threatens a "Bobby Fischer Teaches Chess" back rank mate-in-three with 35. Qf7+ Kh8 36. Qf8+ Rxf8 36. Rxf8#. The only way to stop this threat is 34...Qxf4+, which also happens to win for Black. After the forced reply 35. Qxf4, Black scores the full point with 35...Rf8 +- due to the threatened pawn promotion. Black's decisive error was 29. h3?, allowing 29...Rxd5 -+ (-4.06 @ 28 ply, Stockfish 8). Instead, 29. Kf1 Ref8 30. Qg4 h5 ⩱ (-0.56 @ 30 ply, Stockfish 8) gives White a fighting chance. In the opening, 7. a4 = appears to me to concede equality too easily. Instead, I prefer more active development with the popular moves 7. 0-0 ⩲ to = as in White's win in Navara vs M Agopov, 2016 or 7. Be3 ⩲ to = as in White's win in Eljanov vs E Inarkiev, 2017. |
|
| Feb-13-18 | | SpamIAm: Actually, <patzer2>, even better than a back rank mate-in-three is mate-in-TWO: 35.Qf7+ Kh8 36.Qxe8#. |
|
| Feb-13-18 | | AlicesKnight: Spent a bit of time foolishly wondering whether ....Rf8 wins on its own before finding the game line. <patzer2> is right; the route seems to start after White's 29.h3 but it seems hard to avoid problems. |

 | | whiteshark: <34...Qxf4+ 35.Qxf4 Rf8>, and that's it. |
|

 | | cocker: Fritz 'prefers' 34 ... Rf8, which looks very risky in view of all the checks after 35 Rxf8+ Kxf8. |
|
| Feb-13-18 | | leRevenant: <cocker> I suspect Fritz had a heavy night out on the town. |
|

 | | morfishine: <34...QxR4+> followed by <35...Rf8> and Black wins ***** |
|

 | | malt: With the threat on f7,
34...Q:f4+ 35.Q:f4 Rf8 |
|
Feb-13-18
 | | Del ToRo: Great combination, start with a black queen double attack that provoque a decoy for white queen and finally X-ray attack to protect a candidate pawn |
|
| Feb-13-18 | | dumbgai: If only white didn’t have his g2 pawn he could at least stop the advanced passer with Qxf8+ Kxf8 Kg2. Although black would still win that pawn endgame. |

 | | AylerKupp: <patzer2> Yes, you should never force your opponent to make the winning move. |

| Feb-13-18 | | dfcx: 31...? black to move would be a great puzzle for Wednesday or Thursday. According to Mr. Stockfish, white went down after 29.h3? (-2.89)
white would have kept himself in the game with 29.Kf1 (-0.45) 31.Rxf4?? (-8.30) sealed his fate. |

|
| Feb-13-18 | | zb2cr: Black is in need of a brisk solution--White is threatening mate in three after Qf7+. So Black must deliver check. This cuts down the choices radically. 34. ... Qxf4+ is the move. Since the White Queen also is attacked, White is forced to play 35. Qxf4. Then, Black uncorks 35. ... Rf8. Now, because Black is threatening to Queen at f1, and White's King can't get at the Black Pawn, White has nothing better than 36. Qxf2, Rxf2 and Black has an extra Rook. |
