Not many posts today! Was it really that difficult? I don't think black
found the best defence... |
|
| Dec-12-14 | | diagonalley: ..got as far as 24... P-B3 but failed to perceive that 25.P-R6 was the killer it is... DOH! :-( |
|
| Dec-12-14 | | morfishine: In the given position, <23.Rxe4> is practically a given as there are hardly any other candidates In any case, there are many branches to visualize and perhaps Hort was surprised when Black failed to find the best defense and made things easy with 24...f6; better would've been 23...f6 at once ***** |
|
| Dec-12-14 | | TheaN: Friday 12 December 2014 <23.?> Material is now even, but it's soon going to be imbalanced. Black thought he was free to put a piece in (Be7) at the expense of attacking white's queen with the knight. At first sight, it may seem that white can get two pieces for the rook by capturing on e4 and then e7, but after the queen captures on e4, the rook on h1 is en prise. This justifies black's idea at first glance. Ironically though, white does not really have another option either way. The knight on e4 already thorns into white's position by attacking both the queen and bishop. As such the combination starts <23.Rxe4 Qxe4> Bxg5 will transpose <24.Rg1>. The position that arose now, still has difficulties for black he probably didn't foresee. The bishop is still en prise, and defending it has no use due to the discovered attack on g7. Black has three other options to defend his bishop, but neither eventually work. Trading makes the outposted knight decisive: <24....Bxg5 25.Qxg5 Qh7> after 25....g6 26.hxg6 black is lost, as 26....Qxg6 27.Qd1! and 26....fxg6 27.Nxg6 will already activate white's tremendous knight. <26.h6! g6 27.Nd7 > threatening Nf6 which cannot be defended against, if 27....Qh8 28.h7+! and 27....Kh8 28.Nf6! trapping the queen, and after 27....f6 28.Nxf6+ Rxf6 29.Qxf6 black is lost. Moving allows too many pieces around the king: <24....Bd6> Be7 is harmless due to 25.Be7 Bxe5! 26.dxe5 Qh7!, h6? doesn't work now due to Qxh6, the white queen is not on g5 and after Bxf8 black is fine <25.Bf6! g6> if Qh7, white will windmill to mate 26.Qxg7+ Qxg7 27.Rxg7+ Kh8 28.Rxf7+ Kg8 29.Rg7+ Kh8 30.Ng6#. <26.hxg6 fxg6 27.Qh4!> the double capture on g6 doesn't lead to much. Now white is threatening Qh8-g7-e7#, and black can only stop this by giving back the exchange, yet it is too late <27....Rxf6 28.Qxf6 Bxe5? 29.Rxg6+ Kh7 30.Rh6+ Kg8 31.Rh8#>. Interposing might be black's best bet, but it makes the knight very strong: <24....f6 25.Bh6 g5 26.hxg6 Re8 27.Nf7! > using the strength of the g6 pawn. Now white will shift the queen to the h-file, move the bishop and win. |

 | | Penguincw: All I got was 23.Rxe4, which was pretty obvious. I don't know what it does, but it just seems right. |
|
| Dec-12-14 | | TheaN: Damn, so long and I still missed that in my final line black is fine after <24....f6 25.Bh6 g5 26.hxg6 fxe5 =>, white can keep a small advantage to play Bxf8 after g5. Instead, playing 24.f3! instead of 24.Rg1 is much easier. It keeps the black bishop en prise and threatens the queen. After 24....Qb7 25.h6! black has even less pieces in defense than after 24.Rg1. |
|
| Dec-12-14 | | TheaN: <gofer> the line with 24.Rg1 is insufficient, especially because of 24....f6 25.Bh6 g5! not working. |
|
| Dec-12-14 | | dfcx: 23. ? white to move
White is down a pawn with the queen and bishop under attack. Easiest solution is to eliminate the source.23.Rxe4!
A) 23...Bxg5? 24.Qxg5 Qxe4 25.Rg1 Qh7 26.h6 there is no good defense for black

|
| Dec-12-14 | | patzer2: Running it through Fritz 12 proves this Friday combination more complicated than the game continuation: <23. Rxe4!!> A brilliant move only if White saw it earlier. If 22...Ne5 caught White by surprise, then it's practically a forced desperado. Nothing else gives White any chance of winning. <23...Bxg5>
If 23...Qxe4, White wins with 24. f3! (not 24. Bxe7?? Qxh1+ 25. Qg1 Qxg1#) when play might continue 24... Qb7 25. Bh6 Bg5 26. Bxg7 f6 27. Bxf6 Rxf6 28. Qxg5+ Qg7 29. Qe3 Qb7 30. Rg1+ Kh8 31. h6 Rc8 32. d5 Kh7 (32... Rd8 33. Qd4 Rxd5 34. Ng6+ Kh7 35. Qxf6 ) 33. d6 Rd8 34. Rg7+ Qxg7 35. hxg7 Rh6 36. a3 b4 37. Qe4+ Kxg7 38. Qb7+ Kg8 39. Qf7+ Kh8 40. d7 Rg8 41. Qxg8+ Kxg8 42. d8=Q+ . <24. Qxg5!>
Also winning is 24. f3 Bf6 25. Rg4 Kh7 26. Rg6! Qb7 27. h6! fxg6 28. hxg7+ Kg8 29. gxf8=Q+ Rxf8 30. Nxg6 . <24...f6> Now it's Black with a desperate move. <25. h6!> Black resigns in lieu of the threat 25...fxg5 26. h7+ Kh8 27. Ng6#. If he really wants to drag it out, it's mate-in-seven after 25... Rf7 26. h7+ Kf8 27. Ng6+ Ke8 28. Qxd5 Re7 29. Rxe6 Rxe6 30. Qxe6+ Kd8 31. Qe7+ Kc8 32. h8=Q#. P.S.: Got 24. Rxe4! as my puzzle solution simply because it's a desperado. Everything else either loses or requires computer calculation skill to find drawing chances. Went for 25. Qxg5 because it's a Friday puzzle and this line seemed to offer the kind of complications usually associated with a hard Friday puzzle. In an actual game I'd be content to play 25. f3  to . Was surprised by 24...f6, and missed the brilliant reply 25. h6! with a forced mate. Instead, went for 25. Qg6 when White wins after 25...fxe6 26. h6 Rf7 27. Rg1 . |

| Dec-12-14 | | Castleinthesky: A rare Friday is like a rare steak, got it! |
|
| Dec-12-14 | | kevin86: Black can take the queen, but mate in two is the penalty:25...fxg5 26 h7+ ♔h8 27 ♘g6# |
|
| Dec-12-14 | | Ke2: final move is very nice! i thought it was RxN as it looks promising. 25. Qg6 seems strong as well. |

 | | Jimfromprovidence: In the line 23 Rxe4 Qxe4 24 f3 Qb7 25 Bh6, after 25...Bg5 it gets a bit tricky.
click for larger viewWhite has to be leery about taking the bishop directly because of 26...f6, so the best course could be 26 Bxg7. 
click for larger viewTwo black pieces are now en prise. Play could continue 26...f6 27 Bxf8 Rxf8 28 Rg1.

| Dec-12-14 | | BOSTER: My first surprise was <Chandler>. Something familiar..
<Sally Simpson> vs Hort-impossible.
But he is not Murray.
The final pos. in the game V.Hort vs M.Chandler return my thoughts through Sally-Tal in game Schneider vs Tal,1982 where Tal was lucky because white did not see the brilliant combo in this pos. (diagram).

| Dec-12-14 | | CHESSTTCAMPS: White has a powerful attacking position with the open g-file and aggressive piece placement on the kingside, while black responds with tricky defence. Black threatens Nxg3, Nxg5, Bxg5, and f6, so white must proceed accurately. With the black knight producing the major threats and a queen sac on g3 making no sense, the first move is a no-brainer. 23.Rxe4! and now
A.23...Qxe4? 24.f3 Qh7 25.Bxe7 Rfe8 26.Bf6 Kh8 (Kf8 27.Nd7+ Kg8 28.Rg1) 27.Rg1 fg 28.Qxf6+ wins A.1 23... Qf5 24.Bxe7 Re8 25.h6 g6 (Qh7 26.Bf6) 26.h7+ Kg7 27.Qh4 wins. B. 23... Bxg5! 24.Rg1! (Qxg5?? f6 25.Qg2 fxe5 wins a piece and black should survive the attack) Qxe4 25.Qxg5 Qh7 26.h6! g6 27.Nd7! f6 (otherwise Nf6 forks/traps the Q) 28.Nf6+ Rxf6 29.Qxf6 and there is no defense to 30.Qxg6. B.1. 24... Bh6 25.Rg4! g6 (f6 26.Rxg7+ Kh8 27.Rh7+ Kxh7 28.Qg6+ Kh8 29.Qxh6#) 26.Rxg6+ fxg6 27.Qxg6+ Kh8 28.qxh6# B.2. 24... Bf6 25.Rg4! Bxe5 26.Rxg7+! Kh8 27.dxe5 Qe4 (otherwise 28.Rh7+) 28.h6 followed by 29.h7 then 30.Rg8+ Kxh7 31.Qh2+ can't be stopped. Time for review... |
|
| Dec-12-14 | | CHESSTTCAMPS: Oops - missed the neat mate threat in Note B. Change ?? to !! |
|
| Dec-12-14 | | agb2002: The material is identical.
Black threatens 23... Nxg3 and 23... Nxg5.
The exchange sacrifice 23.Rxe4 looks forced to avoid the loss of the bishop: A) 23... Qxe4 24.f3
A.1) 24... Qxd4 25.Bxe7 Re7 26.Rg1 g6 27.Bf6 followed by hxg6 with a winning attack. A.2) 24... Qh7 25.Bxe7 Re7 26.Bf6
A.2.a) 26... Qh6 27.Ng4
A.2.a.i) 27... Qd2 28.Ne3 g6 (28... Qxe3 29.Qxg7#) 29.hxg6 with a mate attack (29... Qxe3 30.Rh8#). A.2.a.ii) 27... Qh7 28.Be5, with the threats Nf6+ and h6, looks winning (28... Kf8 29.Bd6+; 28... Kh8 29.h6). A.2.b) 26... Ra7 27.Rg1 (threatens 28.Qxg7+ Qxg7 29.Rxg7+ Kh8 (29... Kf8 30.Rh7) 30.Rxf7+) 27... g6 28.hxg6 fxg6 29.Qxg6+ A.2.b.i) 29... Kf8 30.Qg2 with the threat 31.Rh1 looks winning. A.2.b.ii) 29... Qxg6 30.Rxg6+ Kh7 (30... Kf8 31.Rh6 wins) 31.Rg4 and mate in two. B) 23... Bxg5 24.Qxg5
B.1) 24... Qxe4 25.Rg1
B.1.a) 25... Qh7 26.h6
B.1.a.i) 26... g6 27.Ng4 Kh8 28.Nf6 traps the queen.
B.1.a.ii) 26... Ra7 27.hxg7 followed by 28.Ng4 winning. B.1.b) 25... g6 26.hxg6 fxg6 (26... f6 27.Qh6 followed by g7 looks winning) 27.Nxg6 and the black king looks defenseless. B.2) 24... f6 25.h6 Rf7 (25... fxg5 26.h7+ Kh8 27.Ng6#) 26.h7+ Kf8 27.h8=Q+, etc. |

| Dec-12-14 | | Grnhorn: Anyone have yesterdays puzzle link?
or final moves to puzzle? thx. |
|
| Dec-12-14 | | mistreaver: Friday, White to play, Difficult, 23?
The first move is fairly obvious i think, but the rest of puzzle gave me headache
23 Rxe4!
This is forced and obvious. Black has two choices:
A)
23 ... Qxe4
24 Bxe7 Re8
25 Bf6 Qh7
26 Rg1
and i think white will win
B)
23 ... Bxg5
24 Rg4 bf6
25 Rxg7 Bxg7
26 h6
and white probably wins.
Time to check.
------------------
Wow i missed that rook on h1 is hanging in both cases. Shame on me |

My first surprise was <Chandler>. Murray is the black sheep of the family.
No self respecting Chandler would ever play a Caro Kann. |
