|Feb-12-08|| ||johnlspouge: Tuesday (Easy): White to play and win
Material: Down a P. The Black K-side is vulnerable. The White Rg1 attacks Pg6; the Black Rf6 defends Pg6, and is pinned to a point of invasion at h8.
Candidates (37.): Rxg6+
Only two defenses are sensible.
(1) 37...Rxg6 38.Qh8+ Kf7 39.Rh7+ Ke6 [Rg7 does not help] 40.Qe5#
(2) 37...Kf7 (to support Rf6) 38.Rxf6+ Qxf6 39.Rh7+ Ke6 [Kg6 40.Rh6+ loses the Qf6] 39.Qe3+ Qe5 40.Qe5#
Larsen should have resigned after 37.Rxg6+. The solution (completely stated) is slightly complex for a Tuesday, although the difficulty of seeing the key move 37.Rxg6+ is about right.
|Feb-12-08|| ||goodevans: <johnlspouge: 37...Kf7 (to support Rf6) 38.Rxf6+ >
38 Rh7+ looks quicker to me. <Kenkaku> seems to have said something similar, but I think he has got the move numbers wrong.|
|Feb-12-08|| ||just a kid: This was a bit harder than normal on Tuesdays,but when you see the rook pinned to h8 you find 37.Rxg6+! when White wins.|
|Feb-12-08|| ||general607: This one is tougher than most Tuesday challenges. I found the key move, Rxg6 quickly, but only found the mates as I analyzed it deeper. I thought for a moment that Kf7 might hold, then found the mating line there too. Nice multi-option mating problem. I don't see any way out... I also considered Rh6, expecting the king to defend the g-pawn again, then doubling rooks on the h-file with the idea of playing Rh7+ and then either Qe5# if he went to e6 or Rh8+ if he went to the 8th rank, but it seemed to be too slow.|
|Feb-12-08|| ||zb2cr: This one took me a while to see, as for some reason I had an attack of chess blindness in the line 37. Rxg6+, Rxg6; 38. Qh8+, Kf7; 39. Rh7+, Ke6--I didn't see that 40. Qe5 delivered mate! |
Others have commented on the basic lines, and I have nothing meaningful to add.
|Feb-12-08|| ||JG27Pyth: <zb2cr: 37. Rxg6+, Rxg6; 38. Qh8+, Kf7; 39. Rh7+, Ke6--I didn't see that 40. Qe5 delivered mate!> I had the exact same blindness. I kept looking at the line going, "I know this is right, I know there's a win right here what am I missing? |
No more doing the puzzle at 4:30am, even tuesday.
Also... I didn't even bother examing the Kf7 line... and now looking at it in other Kibitzers posts, I think that it takes the puzzle out of Tuesday and into Wednesday difficulty. Calculating to the Qe3 mate is not easy IMO. I mean that's a long long way from the two mover we had yesterday.
|Feb-12-08|| ||tarek1: I lost this puzzle. I saw 37.Rxg6 but chose to continue by 38.Rh8+ Kf7 39.Rh7+, and managed to convince myself that if 39...Kg8 40.Qh8+ was a mate, but black simply covers with the rook (40...Rg8)!|
|Feb-12-08|| ||YouRang: Another case of overwhelming attack.
White has all his heavy pieces focused on black's king position, which is thinly protected.
Such situations call for a sacrifice to bust the defense. When you start looking for a sacrifice in this position, you'll notice your g1 rook jumping up and down and waving both arms. This rook can (1) take out a defending pawn, (2) administer check, and (3) deflect another defender (the rook) out of the way of our queen's diagonal access to h8+.
Anyway, white's army will soon be in black's back yard, and the rest is an excercise in board visualization for about 3-4 moves until mate.
|Feb-12-08|| ||TheaN: 2/2
Nice Tuesday combination with two main variations:
37.Rxg6+ is a crushing punishment for Black's placement. Three moves.
37....Kf8 38.Rxf6+ with the same mates/threats coming as the other variations with a rook down.
37....Rxg6 38.Qh8+ Kf7 39.Rh7+ Rg7 (Ke6 40.Qe5#) 40.Qxg7+ Ke6/8 41.Qf7#
37....Kf7 38.Rxf6+ Qxf6 (nothing else is better for Black) 39.Rh7+ Kg6 (Ke6 40.Qe3+ Qe5 41.Qxe5#) 40.Rh6+ Kxh6 41.Qxf6+ K.O.
|Feb-12-08|| ||TheaN: It's nice to notice the extreme importance of a simple pawn (Pf4) in this combination.|
|Feb-12-08|| ||SwitchingQuylthulg: Got it soon enough (but only after spending some time looking at 37.Rh8+ - I think that idea also wins by force, a sample continuation being 37...Kxh8 38.Rxg6 Qe7 39.Rxf6 Kh7 40.Rxc6 Re8 41.e3 Qh4+ 42.Ke2 Re7 43.Rc8 Qg4+ 44.Kd2 with a totally winning position - but certainly 37.Rxg6+ is much simpler).|
|Feb-12-08|| ||johnlspouge: <goodevans: <johnlspouge: 37...Kf7 (to support Rf6) 38.Rxf6+> 38 Rh7+ looks quicker to me.> |
38...Kxg6 wins for Black, as I and many other people posting must have seen.
|Feb-12-08|| ||wals: Noting think- improve middle game muscle - power up clarity and depth of calculation.
37.Rg1 x g6+ fare? if Kingf8 38.Rh1-h8+
if R x R 38. Qh8 +
Stone the crows mate it's right!

|Feb-12-08|| ||DeepThought: My 1.Rh8+ (1..Kxh8 2.Rxg6) also wins, just a little later...|
|Feb-12-08|| ||eternaloptimist: This was a nice job by the Hungarian GM deflecting Larsen's ♖ off the diagonal. Before that Larsen tried to set up a barricade, but Pinter found a way to break through by exchanging ♙s & pieces. Pretty good combo.|
|Feb-12-08|| ||patzer2: For today's Tuesday puzzle solution, White initiates a mating attack with 37. Rxg6+!|
|Feb-12-08|| ||OBIT: This is an interesting and, IMO, quite ironic game. Larsen used to talk like he'd practically invented the rook pawn thrust to start an attack. He concludes his book "Larsen's Selected Games of Chess" with "I have also toyed with the idea of studying the frequency of the move P-R4 but gave it up..." I think he even wrote an entire book on the subject, called "Strategic and Tactical Significance of the Rook Pawn," or something like that. So, in this game we see his opponent boldly push his h-pawn straight down the h-file and quickly obtain a crushing attack. Maybe he should have tried suing his opponent for copyright infringement, heh heh.|

OK, <OBIT>, now we know why you chose your username.
<heh heh> :>}
|Feb-12-08|| ||Amarande: Oops.
I saw the opportunity to pin Black's Rook while regaining my Pawn (37 Rh8+ Kxh8 38 Rxg6) and after noticing that Black could not defend the Rook further and that I must win (the likely continuation is something such as 38 ... Ra7 39 Rxf6 Kg8 40 Qe5, followed by picking up another pawn or two, not to mention that Black's King is also hopelessly exposed ...), didn't look for something better ...
|Feb-12-08|| ||Billy Vaughan: 37. Rxg6+ seems simple enough, but calculating the mate out to the end threw me. I was looking for material gains and missed Qe6 mate at the end of the 37. ... Rxg6 line.|
|Feb-12-08|| ||DarthStapler: Took a while to get it but I saw the mate|
|Feb-12-08|| ||malvar: I cant believe I missed this one. I must be going blind. I discarded it somehow and started looking for Rh5 with the intention of Rhg5 later. The pawn on g cant capture because of the pin but that doesn't work. After 38.Qh8+, some maneuvering is needed to gain the victory. Somehow mi mind thought it wouldn't work and that eventually black would be up a rook and extra pawns. I guess I need to learn to relax a bit and trust my instincts more. That's very important. I knew it had to be a forced move but just overlooked it.|
|Feb-13-08|| ||kevin86: I found this one- I noticed that moving to h8 with the rook only allows for white to win the queen at the cost of both rooks-an even exchange at best. The text sets up a steamtoller with queen and rook-ending in mate.|
38 ♕h8+ ♔f7 39 ♖h7+ ♔e6 (or ♖g7 40 ♕xg7+ ♔e6 or 8 41 ♕f7#) 40 ♕f5#
|Jan-09-13|| ||perfidious: In this Bogo-Indian cum Dutch Stonewall, Pinter gives a fine illustration of exchanging off the opponent's bad bishop-the piece holding his game together-to deftly end Black's sufferings.|
At the denouement, 36....Qxf6 would have met with the same fate as the game continuation.
An elegant conclusion by Pinter against a formidable opponent.
