 | | Phony Benoni: I didn't even try to solve this, thinking it more important to make sure the details are correct. Everthing appears to be in order, so go to it! |
|
| Dec-26-13 | | PJs Studio: I got it up until 37. Qd7+. Does 37.Rb1+ not work? |

| | Phony Benoni: <PJs Studio> 37.<Rb1+> appears to work as well:
click for larger viewWhite probably preferred 37.Qd7+ since it provides an easy answer to 37...Kxa6 with 38.Ra1+ winning the queen. <37.Rb1+ Kxa6 38.Ra1+ Kb7> just takes a bit longer: 39.Qe7+ Kc8 (39...Kc6 40.Qd7#) 40.Qxf8+, and soon the rooks will crash on to the 7th rank with check and a quick mate. There will probably be more than one alternate solution today. with all the firepower and a king floating in outer space. |

 | | al wazir: What move doesn't win? After 35. Qf3+, black loses a ♖ or the ♕ or his ♔ is hunted to death as in the game line. |
|
| Dec-26-13 | | Jamboree: The solution to the "puzzle" was easy enough -- I (like most everyone here) saw saccing the bishop to lure the rook off the d file, after which one hardly even needs to calculate because it's pretty obvious that one way or the other the king will be hunted to death. HOWEVER, I'm much more curious and mystified about move 16. After 16. Nxf3??, why can't black simply take a free piece with 16. ... Nxc4! ? I mean, what's the refutation? I sure as heck can't see any. That's why I assumed there must be some kind of typo in the game score. Or...what am I missing? |

| Dec-26-13 | | agb2002: White has a bishop for two pawns.
Black threatens 35... fxe6.
The risky position of the black king suggests 35.Be4+: A) 35... Rxe4 36.Qd6+ Kb5 37.Qxf8 + - [R vs 2P].
B) 35... Kb5 36.Rb1+ (36.Bd3 'only' wins the exchange) followed by Ra1+ and Rfb1+ wins the queen. |

| | Phony Benoni: <Jamboree>: My suspicion is that Black actualy played <13...Nf6> instead of 13...Nb6, so that he wasn't attacking the bishop. The knight soon goes to d5, which it could reach from either square. I would certainly consider such a typo more possible than White leaving the bishop hanging. However, I checked Olimpbase and it gives 13...Nb6, so I can't prove that's the wrong move at the moment. And it's Tartakower, so anything is possible. |
|
| Dec-26-13 | | Cheapo by the Dozen: The puzzle is a nice easy one for Boxing Day, as already discussed above. A key point is that Black has no real alternative to accepting the bishop sacrifice. I like <Phony Benoni>'s theory about the possible scoresheet error. |
|
| Dec-26-13 | | morfishine: Can't ask for much more than this: White has material to return, but Black can't accept the offer! <35.Be4+> Black has 2 responses, both losing (1) <35...Rxe4> 36.Qd6+ Kb5 and White can begin a forced mating sequence with 37.Rb1+ or simply play 37.Qxf8 winning a rook (2) <35...Kb5> White now wins Queen for rook after 36.Rb1+ Kxa6 37.Ra1+ Kb5
38.Rfb1+ Qb4 39.Rxb4+
I would expect a player of the stature asTartakower to simply resign after 35.Be4+ *****
PM: I'm surprised, Tartakower decided to play it out

| Dec-26-13 | | mistreaver: Thursday. White to play. Medium. 35?
Not quite as easy as it seems, white is a piece up but black has many pawns,
and there are many continuations that look tempting for white.
But i think the key is in preserving the e pawn and then gettint through to the black king say
35 e7 Re8
36 Qf3+
Now black has many king moves:
A)
36... Kb5
37 Bd7+
and
B)
36 ... Kc7
37 Qb7+ Kd6
38 Qd7+ and that should be kill in a few moves
C)
36 ... Kd6
37 Rxd4 cxd4
38 Qf4+ Kxe7
39 Re1+ and here it is surely mate again
D)
36... Qd5
37 Bd7+ is also a win.
Time to check.
---------------
Hmmm, i missed the very strong and instantly winning Be4+, but white position is so strong that e7 also wins without many problems. |

| Dec-26-13 | | avidfan: I would tend to agree with <mistreaver>. But 35.Be4+ Rxe4 36.Qd6+ Kb5 37.Qd7+ Ka5 38.Ra1+ Kb4 39.Qa4+ Kc3 40.Ra3+ 
click for larger viewreaches a puzzle position after
40... Kb2. Can White mate soon seeing that a2 and e2 are covered by the Black Queen? |

| Dec-26-13 | | avidfan: 40.Rac1+ Kd2 41.Qd1+ Ke3 42.Rf3#

|
| Dec-26-13 | | Nick46: Getting the first couple of moves and reading PB's <There will probably be more than one alternate solution today, with all the firepower and a king floating in outer space> I feel vindicated on Boxing Day. |
|
| Dec-26-13 | | morfishine: <avidfan> The most forcing move-order is 35.Be4 Rxe4 36.Qd6+ Kb5 <37.Rb1+> not <37.Qd7+??> If the Black King ignores White's a-pawn and tries to zig-zag thru White's Q-side, eventually the Black Queen gets forked: 37.Rb1+ Ka4 38.Ra1+ Kb3 39.Rfb1+ Kc2 40.Rc1+ If the Black King takes the a-pawn, he is quickly lost after 37.Rb1+ Kxa6
38.Ra1+ Kb7 39.Qd7+ Kb8 40.Qxa7+ Kc8 41.Qd7+ Kb8 and here one simple winning method is 42.e7 ***** |
|
| Dec-26-13 | | Prosperus: A more interesting mate would be with 40. Qd2+! Kb3/Qc2 41. Rfb1# |
|
| Dec-26-13 | | WoodPushkin: Greetings
35.Be4+ is easy enough and the overwhelming continuations which all lead to Blacks quick or slow mate. What I take away from this game is the positional domination by Soultanbeieff after move 19...Qg5? While it seems logical enough to x-ray king, hit knight and create support for an eventual f5, Tartakower seems to forget about king safety. Whites Q, R's, N and pawn are able to exert serious pressure on Blacks casteled queen side. The 'a' pawn alone causes the loosening of Blacks defenses after Tartakower gives White a great bishop?! I'm not too familiar with Tartakower games but he seems to play this game w/o a lot of respect for his opponents skills and is soundly thrashed for it. Perhaps he was relying on experience when he should have been playing the board. |

 | | Domdaniel: 35.Be4+ jumps out, though I'd probably then bail with 37.Qxf8. |

| Dec-26-13 | | RandomVisitor: After 13.Nd2: the eval suggests, as do others, that 13...Nf6 was actually played
