| Sep-29-15 | | zb2cr: A Rook down, White must seek mate.
27. Bxf7+!
Black will be mated speedily after either 27. ... Kxf7 or 27. ... Kf8. If 27. ... Kxf7; 28. Rh7+, Kf8; 29. Qg7#.
If 27. ... Kf8; 28. Qg8+, Ke7; 29. Qxe8#.
As <CHESSTTCAMPS> points out, in the 27. ... Kf8 line, 28. Rh8+ also works. |
|
| Sep-29-15 | | ASchultz: A fun attack for White. ...Bxc3! after f4 would've been ruinous, but when people are under pressure, they miss this sort of thing. |
|
| Sep-29-15 | | agb2002: White has a knight and a pawn for a rook and a bishop. White delivers mate in three with 27.Bxf7+:
A) 27... Kxf7 28.Rh7+ Kf8 29.Qg7#.
B) 27... Kf8 28.Qg8+ Ke7 29.Qxe8#. |
|
| Sep-29-15 | | stst: 27.Rh7+ Kf8
(IF ... Kg8, 28.Bxf7+ Kxh7, 29.Bxe8 and White wins the exchange and wins easily.)
28.Qg5
IF (A)
.......... Bd8
29.Rh8+ Kg7
30.Qh6#
IF(B)
...........fxg6
29.Qf6+ Kg8
30.Qg7#
IF(C)
..........Qe7
29.Rh8+ Kg7
30.Qh6#
see what else... |
|
| Sep-29-15 | | Cybe: Bd3+ - mate in 5; Nd4 - mate in 9; Qh4 - mate in 12, ... |
|
| Sep-29-15 | | saturn2: First observation: Black is a rock up, so winning the queen for another rock is not enough (for instannce after 27Rh7+ Kg8, 28 Bd3+ Kf8 29 Rh8+ etc) But white has more: 27 Bf7+ Kf8 followed by either 28 Rh8+ or 28 Qg8 winning the queen (this time without investing the second rock) or the game. |
|
| Sep-29-15 | | Once: A discovered check is a cannon primed with gunpowder and loaded with a cannonball. All the time that the discovered check is possible, both sides simply have to calculate the effect of firing the cannon. What happens if we fire? Then the question becomes "which bishop move?". And as Phony says if you have red blood in your veins you simply have to start by looking at Bxf7+. M'learned colleagues have described the moves more eloquently than I could. Bang, bang, you're dead. |
|
| Sep-29-15 | | stacase: <Phony Benoni: When in doubt ....> First chuckle of the day. |
|
| Sep-29-15 | | bachiller: After 27. Bxf7+, Kf8, I chose 28. Qg5, threatening Rh8. Mate will come soon afterwads. May I claim some prize (e. g. for the weirdest choice of 28th move)? |
|
| Sep-29-15 | | Lambda: When you look at that starting position, it's not immediately obvious how the black rook could have got to a1. |
|
Sep-29-15
 | | Penguincw: I missed the quick knockout, and found to slower win: 27.Bf7+ Kf8 28.Rh8+ Ke7 29.Rxe8+ Kxe8. Looks winning, but could take some time. |
|
Sep-29-15
 | | Bubo bubo: 27.Bxf7+ with mate after either
A) 27...Kxf7 28.Rh7+ Kf8 29.Qg7# or
B) 27...Kf8 28.Rh8+ Ke7 (or 28...Kxf7 29.Rh7+ as above) 29.Rxe8+ Kd7 30.Qxe6+ Kc7 31.Qd6# / 29...Kxf7 30.Qg8# |

| | pittpanther: Question: Could black have survived after 26 ... Qxh3 followed by fg? If white takes the queen with his queen and then plays Ng5 seems black can play Kf8 and run away to d8 and white does not have enough pieces left to mate him. If white takes the queen with the pawn and then tries Nh4 then black can play Rg1 to protect the g6 pawn. (Although maybe I am missing a simple mating net.) |
|
| Sep-29-15 | | Skewbrow: I, too, was pondering whether black could have saved the day with 26...Qxh3 27. Qxh3 fxg6. After all, two rooks are (in terms of material) a match to a queen, and black would keep a pair of bishops to white's knight. But it seems clear to me that the white attack on the defenseless king will win. A king chase starting out 28. Ng5 Kf8 29. Qh8 seems to be enough. Often the white queen ends up in d6, where it either mates (if the black king is in c7) or allow the knight the move closer (if the black king is in d8). |

| Sep-29-15 | | whiteshark: a fatal double check |

| | NM JRousselle: I was thinking Bd3+ followed by Qg5. |
|
| Sep-29-15 | | kevin86: White strikes quickly and mates quickly...black also has a quick mate...but alas it's not his turn. |
|
| Sep-29-15 | | starry2013: I wasted a bit of time thinking rook check as is forcing. But apart from rook for queen and chasing the king and maybe taking a pawn it wasn't as good as I'd hoped. One I played the bishop takes it really played itself. |
|
| Sep-29-15 | | starry2013: by rook check I meant Rh7. |
|
| Sep-29-15 | | TimothyLucasJaeger: I went with the quieter move 27. ♕g5, not sure if i missed something. A. 27. ... fxg6 28. ♕f6+ ♔g8 29. ♖h8#
♗. 27. ... ♔f8 28. ♖h8+ ♔g7 29. ♕f6#
C. 27. ... ♗d8 (♕d8) 28. ♕h6+ ♔g8 29. ♕h8#
D. 27. ... ♕b5+ 28. ♗d3+ ♔f8 29. ♖h8#
E. 27. ... ♔g8 28. ♗b1+ (et al) ♔f8 29. ♖h8#
F. 27. ... ♖e1+ 28 ♘xe1 changes nothing. |
|
| Sep-29-15 | | Zhbugnoimt: One of my opponents in a recent tournament game got his rook to h1 in the same way. My rook had not yet moved, while his was very active and supporting a lot of threats. By going to take my rook, he lost 5 points. My rook on h1 was in effect worth 0, while his was worth the full 5. On h1, his worth turned from a 5 into a zero. |
|
| Sep-29-15 | | patzer2: The decisive mistake appears to be <24...Rh1+?> allowing 25. Ke2  (+3.42 @ 23 depth, Deep Fritz 14).Instead, Black appears to be winning with 24...fxg6! when play might continue 25. Qxg6+ Kf8 26. Ng5 Rh1+ 27. Ke2 Qh5+ 28. Qxh5 Rxh5  (-1.70 @ 23 depth) . Quickly found the initial move 27. Bxf7+! in today's Tuesday puzzle solution. However, in the follow-up, I stretched out the mate for one extra move with 28. Rh8+ Ke7 29. Rxe8+ Kd7 30. Qxe6+ Kc7 31. Qd6#. |
|
| Sep-29-15 | | BOSTER: This is always not good idea to keep your King on the same line with opponent's queen or rook.
This the pos. Black to play 19...

After 19...Kf8 if 20.Bxg6 fxg6 21.Qxg6 Qf7 white has to prove that he is better. |
|
| Sep-29-15 | | psmith: I love Mondays.
Oh. :) |
|
| Sep-29-15 | | HowDoesTheHorsieMove: I saw this as needing win the queen outright considering white is a rook down, so I chose 27. Bc2+ Kf8 28. Rh8+ Ke7 29. Qg5+ Kd7 30.Ba4+ Kc7 and a free queen with either RxQ or BxQ. Not quite as good as the solution, but enough for me to stop looking. |
