 | | offramp: Rather a neat mate after 36...Kd6 37.Qc7. |
|
| Sep-07-13 | | morfishine: White is up a piece but is forced to return the material There are 3 candidates to look at:
(1) <34.Be8+> 34...Kxe8 (Or 34...Ke7 35.Bxb4+ Kxe8 36.Rc8 +Kd7 37.Qxg7+ Kxc8
38.Qxf6 Nd7) 35.Rc8+ Kd7 36.Qxg7+ Kxc8 37.Qxf6 Qxd2 38.Qxf8+ Kd7 Looks drawish (2) <34.Qxf8+> But this is no good due to 34...Kxf8 35.Bxb4+ Kf7 and the duel threat 36...Qf2+ & 36...Qxe3+ is too much for White (3) <34.Bf3> 34...Rxf3 35.gxf3 Qxd2 36.Rc7+ Ke8 37.Rc8+ Kd7
38.Qxf8 Qxe3+ 39.Kg2 Qd2+ 40.Kh3 and White wins
So, all in all, variation #3 looks the most promising *****
PM: Black chose the quickest, less painful path

| Sep-07-13 | | Dr. Funkenstein: White to play up a bishop for a pawn but about to get mated on f1 after Qf2+ Bf3 and Be8+ seem like to the only moves to get the c1 rook into play 34. Be8+ Kxe8 (Ke7 35. Qxg7+) 35. Rc8+ Kd7 36. Qxg7+ Kxc8 goes nowhere fast as white ends up at best with even material after regaining the rook and black’s queen better placed or maybe even down a knight So we go with
34. Bf3 Qxd2 35. Bh5+ and no matter how black blocks, Rc7+ is going to win the f6 rook and there’s no back rank threat after that -----
Didn’t consider 35. …Ke7 but this allows Qg7+ and Qc7# |
|
| Sep-07-13 | | JSYantiss: offramp, if 37. Qc7+, Black King moves to d5. No mate. |
|
| Sep-07-13 | | bubuli55: Just trying to help :)
35... Ke2 36. Qxg7+ Kd6 37. Qc7+ Kd5 38. Qc6+ Ke5 39. Rc5# |

 | | emelman: So it looks like 30...d4 is the losing move! It seemed a reasonable attempt to activate the queen via d5 but whites 31. c6 blows it up! My first thought was 30...e5 to continue the game. Good fighting chess! |
|
Sep-07-13
 | | Penguincw: Woah. I was thinking of 34.Be8+ and so on, but it looks like it's a losing variation. |

Way to go, <bubuli55> 35...Ke7, 36. Qxg7+ Kd6, 37. Qc7+ Kd5, 38. Qc6+! (not allowing the Black King to escape from checkmate) Ke5, 39. Rc5# 1-0 <bubuli55> Many thanks!!! I wasn't able to solve that, I admit SuperPatzer77 |
|
| Sep-07-13 | | kevin86: White's 34th attacks and defends at the same time. The attack frees the white queen from her "cornered" status and forces the victory. |
|
| Sep-07-13 | | Refused: Black threatens
34...Qf2+ with Qf1 to follow.
Slow moves like h3 look horrible, with moves like dxe3 in the air.34.Bf3 parries all the Qf2+ threats, opens the c-file. 34.Bf3 Qxd2
35.Rc7+ Ke8
36.Bh5+ g6
37.Qxf6 and white should be winning
36...Kd8 ok, now I have a problem. Mating threats and a hanging rook. Let's switch the move order 34.Bf3 Qxd2
35.Bh5+ g6
36.Rc7+ transposes into my first line.
35...Ke7
36.Rc7+ does not work, meh. but what about
36.Qxg7+ yeah. that looks good, let's continue that path.
36...Kd8 37.Qxf6+ Kd7 38.Qf7+ ok, either to d6 or drop another piece.
36...Rf7 37.Qxf7+ well that didn't really help
36...Kd6 37.Qc7+ Kd5 38.Qc6+ Ke5 39.Rc5# forces the mate. So yeah.
34.Bf3 Qxd2 35.Bh5+! Ke7 36.Qxg7+ Kd8 37.Qc7+ Kd5 38.Qc6+ Ke5 39.Rc5# |
|
| Sep-07-13 | | patzer2: I went for 34. Be8+, giving up the wrong Bishop which leaves White with nothing better than a draw. One drawing line from Fritz 12 goes 34. Be8+ Kxe8 35. Rc8+ Kd7 36. Qxg7+ Kxc8 37. Qxf6 Qd1+ (37...Qxd2 38. Qxf8+ transposes) 38. Qf1 Qxd2 39. Qxf8+ Kc7 40. Qc5+ Kb7 41. Qe7+! Kb8 42. Qd6+ Kb7 43. Qd7+ Kb8 =. I considered 34. Bf3!!, but after 34. Bf3!! Qxd2 only looked at 36. Rc7+ and 36. Rf1. Realizing Black's threats are too strong after 35. Bf3!! Qxd2 36. Rc7+ (36. Rf1 Qxe3+! 37. Kh1 Rxf3! 38. gxf3 d6  ) Ke8! Rc8+ 39. Kd7 , I passed on 34. Bf3!! and went for 34. Be8+ instead. What I failed to consider was the stronger 35. Bh5+!, which is not only the winning follow-up but also the only move that doesn't lose after 34. Bf3!! Qxd2. |
|
| Sep-07-13 | | patzer2: Earlier in the game, Black's decisive mistake was 30...d5?, allowing the winning 31. c6! (a strong move worthy of a future daily puzzle position). Instead 30...Nc6 = to  holds. |
|
| Sep-07-13 | | cyclon: In Today's Puzzle I'd go for 34. Bf3 and here some illustrations; 1. 34. -Rxf3 35. gxf3 ( 35. Rc7+ Ke8 36. gxf3 dxe3 Black threatens soon by perpetual because White can't play here 37. Be1 and on 36. Bxe3 Qxe3+ there's again perpetual threat yet possible -Qe5+ fork taking Rook on c7 ) and NOW; -35. -dxe3 36. Be1 White should win, or -35. -Qxd2 ( 35. -Qxf3?? 36. Rf1 ) 36, Rc7+ Ke8 37. Qxg7 and NOW -37. -Qxe3+ 38. Kg2 Qe2+ 39, Kh3 Qf1 40. Qg2 White should win , or -37. -Qe1+ 38. Kg2 Qe2+ 39. Kg3 Qe1+ 40. Kh3. 2. ( 34. Bf3 ) -34. -Qxd2 35. Bh5+ g6 ( 35. -Ng6? 36. Rc7X, or 35. -Rg6? 36. Rf1+ both goodbyes ) 36. Rc7+ Ke8 37. Qxf6 and because mate 38. Qe7X Black has to exchange Queens either by -37. -Qe1+ 38. Qf1 Qxe3+ 39. Qf2 Qxf2+ ( 39. -Qg5 40. Rxc8+ and 41. Rxf8 / 39. - gxh5 40. Qxe3 dxe3 41. Kf1 Black loses the ending ) 40. Kxf2 gxh5 41. Rc6 White should win the ending quite comfortably, but should still play accurately. 3. ( 34. Bf3 ) -34. -Qb5 35. Rc7+ Nd7 ( 35. -Ke8 36. Bc6+, or 35. -Kg6 36. Qxg7+ Kf5 37. Qg4+ Ke5 38. Qd4+ Kf5 39. Qe4+ Kg5 40. Qg4X ) 36. Bh5+ g6 ( 36. -Rg6 37. Bxd6+ Kxg6 38. Qe8+, or 36. -Ke7 37. Qxg7+ Kd6 [ 37. -Kd8 38. Rxd7+ Qxd7 39. Qxf6+ ] 38. Rxd7+ Qxd7 39. Qxf6 and BK blocks d-file ) 37. Qh7+ K- 38. Rc8X. So, here are my grounds for White's 34. Bf3 to achieve a winning game. Let's see. |
|
| Sep-07-13 | | cyclon: I had also this line among my first analysis, but left move 35. -Ke7 out of mention ( or forgot it ) instead of my 35. -g6 which also loses as I have shown. 35. -Ke7 (?) leads to mate by; ( 34. Bf3 Qxd2 35. Bh5+) -35. - Ke7(?) 36. Qxg7+ Kd6 ( 36. -Kd8 37. Qc7X ) 37. Qc7+ Kd5 38. Rc5+ Ke4 39. Re5+ Kd3 40. Qc4X. |
|
| Sep-07-13 | | agb2002: White has the bishop pair for a knight and a pawn.
Black threatens 34... Qf2+ and mate in two, 34... Qxd2, 34... dxe3, etc. The first idea that comes to mind is 34.Bf3, stopping the mate and threatening Bxe2, Rc7+ and Bh5+: A) 34... Qxd2 35.Bh5+
A.1) 35... Ke7 36.Qxg7+ Kd6 (36... Kd8 37.Qc7#; 36... Rf7 37.Qxf7+ Kd6 38.Qc7+ Kd5 39.Bf3#) 37.Qc7+ Kd5 38.Qc6+ Ke5 39.Rc5#. A.2) 35... Rg6 36.Rf1+ Ke7 37.Qxf8+ Kd7 38.Rf7+ Kc6 39.Bf3+ Rb5(6) 40.Rb7+ Ka5 41.Qc5(d8)#. A.3) 35... Ng6 36.Rc7#.
A.4) 35... g6 36.Rc7+ Ke8 (36... Nd7 37.Rxd7#) 37.Qxf6 Qxe6+ 38.Qf2 Qxf2+ 39.Kxf2 gxh5 40.Ra7 with a won ending. B) 34... Rxf3 35.gxf3
B.1) 35... Qxd2 36.Rc7+
B.1.a) 36... Ke8 37.Rc8+ Kd7 38.Qxf8 threatening mate and protecting the f-pawn looks winning. For example, 38... Qxe3+ 39.Kf1 Qd3+ 40.Ke1 Qb1+ (else the king goes to the queen side and covers the checks with the rook) 41.Kd2 Qxa2+ 42.Rc2 Qxb3 43.Qxg7+ Kd6(8) (43... Ke8 44.Rc8#) 44.Qxd4+ with a mate attack. B.1.b) 36... Kf6 37.Qxf8+ Kg5 (37... Ke5 38.Rc5#) 38.Rxg7+ and mate soon. B.1.c) 36... Kg6 37.Qxg7+ Kf5 (37... Kh5 38.Qg4#) 38.Rf7#. B.2) 35... Qxf3 36.Rf1 wins.
B.3) 35... dxe3 36.Be1 Qxf3 37.Rc7+ looks similar to previous lines and also winning. |

| Sep-07-13 | | mistreaver: Saturday. White to play. Very difficult. 34?
White is a piece up but Black has irresistible mating threats. That actually makes our task here easier
because white's play will probably be forced.
Some of ideas that are apparent are bishop check on b4, and removing the white LSB so rook can come in and join the attack.
Some quiet move like 34 h3 just defending against mate is probably no good since after 34... Qxd2 white is just in bad way.
The move i would probably start calculating in OTB game is:
34 Be8+
Now it is a good moment to remember the writings of an old English gentleman: "To take or not to take that is the question"
A) let's first try the primitive way:
34... Kxe8
35 Rc8+ and now another branch:
A1)
35 ... Ke7
36 Bxb4+ Kd7 is same as A2) variation but white has removed his d2 bishop from attack with tempo
A2)
35 ... Kd7
36 Qxg7+ (else white will be mated on 1st rank)
36 ... Kxc8
37 Qxf6 Qd1+
38 Qf1 and now:
A21)
38 ... Qxf1
39 Kxf1 leaves white with a better endgame
A22)
38 ... Qxd2
39 Qxf8+ Kd7
and i think white should be better here, but i am not sure how much and whether it is won or not
B)
34... Ke7
35 Qxg7+ is not good here
Time to check and see how the game really went.
-----------------
Yep, i calculated well, and evaluated very well, but didn't consider all the candidates in the position, 34 <Bf3> is exceptionally nice way to win.
The endgame in question is following(arising after my variation A22):
click for larger view
after
40 exd4 Qxd4+
41 Qf2 Qa1+
42 Qf1 Qxa2
it will probably end in a perpetual check. |
|
| Sep-07-13 | | Marmot PFL: In view of black's threats (like 34...Qf2+) 34 Bf3 seems forced, therefore not too hard to find. One line might be 34...Qxd2 35 Bh5+ Ke7 36 Qxg7+ Kd6 37 Qc7+ Kd5 38 Qc6+ Ke5 39 Rc5 mate and also 34...Rxf3 35 gf de3 loses to 36 Rc7+ Ke8 37 Rc8+ |
|
| Sep-07-13 | | Abdel Irada: <34. Bf3 to block, please.> Black could have put up a slightly longer fight, but the finish in the variation played would have been pretty if played out: <34. Bf3, Qxd2
35. Bh5†, Ke7?>
Somewhat more durable is 35. ...g6 (not 35. ...Ng6?? 36. Rc7#) 36. Rc7†, Ke8 37. Qxf6, and wins since Black has no productive checks and will remain down the exchange. <36. Qxg7†, Kd6>
Not 36. ...Kd8?? 37. Qc7#.
<37. Qc7†!, Kd5
38. Rc5†, Ke4
39. Qe5†, Kd3
40. Qxd4#>

| Sep-07-13 | | Patriot: Black threatens 34...Qf2+ 35.Kh1 Qf1+ and mate next. Black also threatens 34...Qxd2. The very forcing 34.Qxf8+ Kxf8 35.Bxb4+ Kg8 doesn't seem to work. 36.Bf3 Qxe3+ followed by 37...Qxc1+. 34.Bf3 stops one threat and allows the other: 34...Qxd2 35.Rc7+ Ke8 36.Rc8+ Kd7 37.Qxg7+ Kxc8 38.Qxf6 Qc1+ 39.Qf1 Qxe3+ 40.Kh1 looks somewhat double-edged. 34.Be8+ also looks very interesting to me. 34...Kxe8 35.Rc8+ Kd7 36.Qxg7+ Kxc8 37.Qxf6 Qxd2 38.Qxf8+ or 37...Nd7 38.Qf2 seems advantageous to white. 34.Be8+ is more forcing but it seems a difficult choice because things aren't completely clear to me and I've already spent too much time on this. I'll go with 34.Be8+. |
|
| Sep-07-13 | | Patriot: Ok, in the 34.Bf3 line I missed 38.Qxf6?? Qe1#. 35.Bh5+ is the only move--everything else loses! 34.Be8+ is a draw. |
|
| Sep-07-13 | | Patriot: I guess I should have been more attracted to 35.Bh5+ first as a principle of getting more pieces in the attack! The rook is already poised to move in with check. Sometimes simple principles can help guide you to more efficient lines to consider first. |
|
Sep-07-13
 | | FSR: White looks to be in trouble, but 34.Bf3! toasts Black: 34...Rxf3 35.gxf3! Qxd2 36.Rc7+ Ke8 (36...Nd7 37.Rxd7+ Ke6 38.Qe8+ ; 36...Kg6 37.Qxg7+ Kf5 (37...Kh5 38.Qg4#) 38.Rf7#) 37.Rc8+ Kd7 38.Qxf8 Qxe3+ 39.Kh3! and Black has run out of checks. 34...Qxd2 35.Bh5+! g6 (35...Ng6 36.Rc7#; 35...Ke7 36.Qxg7+ Kd6 37.Qc7+ Kd5 38.Rc5+ Ke4 39.Re5+ Kd3 40.Qc4#) 36.Rc7+ Ke8 37.Qxf6 Qxe3+ 38.Qf2 |

| Jul-17-22 | | Messiah: 34. Bf3! Excellent move! |
