|Mar-31-06|| ||dongrimace: awts!!!i failed to solve this problem ..took me a 15 mins. to figure dis problem.. i was thinking 32.Bb6.. the if 32..Qxb6 then 33.rxd7 winning a queen but 33...kXd7 34.Qxb6 but i saw 34...Bxe1 for black to resist the game.|
|Mar-31-06|| ||peabody88: First Friday puzzle I get in a very long time. Bring on the weekend puzzles!|
|Mar-31-06|| ||kevin86: Great queen sac from the blue!! I tried the bishop,but the king squirmed away via d8.|
|Mar-31-06|| ||babakova: <dongrimace> I thought 1.Bb6 too for a while but your 33.Rxd7?? is a poor choice on 32...Qxb6? since he should play 33.Qf6+! Nxf6 34.gxf6+ Kf8 35.Rh8. That is what I calculated anyway until I realized white could play Qf6 immediately.|
|Mar-31-06|| ||jmuller: It's always helpful to me to see the thought process others follow. So, I'll share mine. :-) |
On this one, I immediately saw that Qf6 would lead to mate, except for Black's protecting knight. So, I noodled around a couple of minutes trying to figure out how to move his knight. Well, I couldn't do anything there, so I figured, heck, 31.Qf2 is the most forcing move on the board; let's see what happens. The rest was simple.
Someday, John, maybe I'll learn to take Tal's advice and check out the most forcing moves first! Boola Boola <g>
|Mar-31-06|| ||Sleepyeyeguy: If the solution is as easy as I think it is I'll be quite disappointed considering it is indeed a Friday puzzle. (this is before looking at the answer) I see 32.Qd6+ Nxd6 33.Bc5+ Bxc5 34.gxf Kg8 35.Rh8#|
|Mar-31-06|| ||Zplane: Problem is with these puzzles is you know it will be something dramatic and automatically look to sac the queen. Probably not realistic evaluation techniques as compared to real games.|
|Mar-31-06|| ||Sleepyeyeguy: << Is disappointed...This was way too easy for a Friday puzzle. Yesterdays was much harder|
|Mar-31-06|| ||belka: I had the same idea, sacrifice the queen on f6 to clear the c5 square and d file, but I wanted to throw in c3 first to deflect the bishop.|
It is not as clean, of course. I missed that after gxf6+, the king is mated on f8 anyway and the deflection is not needed.
I calculated that since Bxc3 loses to Qf6+ and Bc5+, black is losing a piece. I didn't look any further to comfirm that it's winning. Probably is, but mate in 3 is surely better than winning a piece.
|Mar-31-06|| ||dakgootje: Hard week for me this week, still even though that i had a 4/4 this week, but missed this one, so down to 4/5 ;-)|
Still going to try to get at least a 5/7 this week, which is of course possible, as tomorrow since months im going to set up the position on my board again (not moving the pieces, all calculating in my head) as that proves to help often.
|Mar-31-06|| ||ckr: <jmuller> A very interesting thought process. But how did you conclude 31.Qf2 when the puzzle presented had the queen on f2 already? The position is the same as it was earlier this morning.|
|Mar-31-06|| ||ckr: <belka> after 32.c3 black has 32...♖h8 33.♖xh8 ♖xh8 34.cxb4 ♔e8 the position is still overwhelmingly in whites favor but the game drags out.|
|Mar-31-06|| ||YouRang: I found the 32. Bc5! solution. It's not the one played (and not quite as good), but I'm satisfied that it wins.|
Black has two replies that both lose:
33. Qf6+! Nxf6
34. gxf6+ Kf8
33. Qxd7 (threatens Qxd7#) Qb7
34. Bb6+!, and mate next move
(34...Qxb6 35. Qxd7# or 34...Kc8 35. Qxe8#)
The key to finding the win is to notice the potential for Rh8# if we can force the king to f8 with a pawn at f6. :-)
|Mar-31-06|| ||Alex S.: For the purposes of closure:
34. exf6 Kf8
34. gxf6 Kf8
works just as well.

All of this is possible because black has thrown all his pieces on the queenside, and the poor king is a lonely piece imprisoned on the kingside with no defenders>. 28...Ke7 29.Bxc6 bxc6 30.Bd4 Bb4 31.Qf2 Nd7?? <31...Nd5 32 Bc5+ Bxc5 33 Qxc5+ Kd8 34 bxc4 is still winning for white.> 32.Qf6+ Nxf6 33.Bc5+ 1–0
Black totally disregards the safety of his king, and there is no defender in sight.
Nice play by Vladimirov, and a neat combination to finish!
|Mar-31-06|| ||peabody88: <YouRang> I assume that you meant 33.♕xf7 (threatens ♕xd7) but in that case you can answer 33... ♖a7 that would give up the exchange but delay the mate|
|Mar-31-06|| ||jmuller: My apologies, ckr. I meant 31.Qf6, not 31.Qf2. Does that make more sense? :-)|
|Mar-31-06|| ||Chicago Chess Man: The difference between masters like this and a patzer like me is I would've played 28. Qh8+ probably without hesitation|
|Mar-31-06|| ||YouRang: <peabody88> <I assume that you meant 33.xf7> Yes I did, thank you.|
<in that case you can answer 33... Ra7 that would give up the exchange but delay the mate> I should have mentioned that line, but I think White still mates in short order:
After 33...Ra7, White should play 34. Rh7!, piling up on the poor d7 knight (now pinned in two directions). Black can try 34...Qc8, but again 35. Bb6+ and its all over (diagram:black to play)

The knight will fall, in futility Black will offer pieces to White to delay mate, and then it will be mate.
|Mar-31-06|| ||The17thPawn: 4 out of 5 for the week is not to shabby! Love the zwischenzug Vladimirov uses to polish off his opponent. Hoping for 5 of 7 for the week like <dakgootje>, but weekend puzzles usually confound me.|
|Mar-31-06|| ||Fezzik: I agree with most of the players here that today may have been the easiest position of the week. |
John Nunn's axiom (which he probably got from someone else), "Always Analyse Forcing Moves First" coupled with the older idea of looking for ways to sacrifice your queen made this especially easy.
I glanced at 32.Bc5+ after I'd already found 32.Qf6+ leading to mate, but I came to the same conclusions as most commentators. 33. Qf6+ is both more efficient and more spectacular. This was a nice finish by Vladimirov!
By the way, Kharitonov showed good sportsmanship in not resigning when 32.Qf6+ was played, allowing Vladimirov to show off his idea over the board.
|Mar-31-06|| ||Halldor: The position of the black king was critical so I decided to begin with the most dramatic attacking move, the queen sac 32.♕f6 ♘x♕ but then I went off the right track by 33.gxf6??, so I tried 32.♗c5, but the king seemed to escape via d8, that was boring so I didn't look as deep into that line as <YouRang>, - mainly because then I started to think about closing the d-file and immediately found the right continuation as in the game. There the second move (33.♗c5) is actually the key move.|
Did somebody say this was too easy for a Friday puzzle...? Well, I'm delighted that I could solve it. Very good puzzle.
|Mar-31-06|| ||goldenbear: Nice puzzle, good comments. Took me a minute to see the Bc5 follow-up but I knew Qf6 had to be right. I never considered Bc5 immediately or any other move. I think that has something to do with me being an "auditory" person in general. I'd rather hear a math problem than see it. Qf6 just sounds like the right idea.|
|Mar-31-06|| ||OBIT: Well, like a few other posters, I went with the inferior 32. c3, but it does at least win a piece. Forced mate by a queen sac is better, of course. :) |
Anyway, after 32. c3, I can't see too many tournament players accepting a piece-down position just to delay mate. You'd probably see either (a) 32...c5, when 33. Be3! retains all White's threats, or (b) 32...Ba3 (or 32...c5 33. Be3! Ba3). In the latter line, White can win the bishop anyway by 33. Ra1, but that messes up his nice attacking formation. Instead, 33. b4! to cut off the bishop looks crushing.
|Mar-31-06|| ||aazqua: I like the "inferior" c3 (the solution i found) as well. It's fairly easy to spot and leads to a clear win.|
