  kevin86: I missed this one-mostly because these Saturday puzzles rely on the third and fourth moves-and even farther down the line moves. I am too warn out on a weekend to go into so much depth.

I like black's treatric final move (36...Bh1)-it had a neat shock value-but didn't stop white for a second in his mate quest.

Aug-25-07   Halldor: I went for 30. Re7 as many; only looked briefly at 30. f7+ Kg7 and stuck there - thought that the bishop were defending e8, silly! (didn't see 31. Re8 BxR?? f8Q and mate in 2).

After 30. Re7 however then there is a forced line, 30... Qf8 31. Rg7+ with a mate threat, so Black has to give his queen for rook and pawn and his position seems to be very bad if not lost.

Aug-25-07   4i4mitko: ok sorry thanks i often don't see horizontals:)))
Aug-25-07   Dr.Lecter: The king hunt is interesting enough. All the other pieces are too far away to be too much of help. I thought the same thing as <dzechiel>, unfortunately.

  Gilmoy: Even material. White has an f6-pawn trapping Black's K; Black has a passed d4-pawn. White's K is exposed, but Black's pieces are rather passive, and have no immediate threats.

White's Q must defend f6, so Qxh6 doesn't work. Trading Bs just gives Black a free double on f6, forcing White's R into passive defense.

Deflect-and-push is pretty obvious, but there's a better continuation:

29.Bxg6

[A] fxg6 (clears 7) 30.Re7 costs Black's Q.

[A1] 30..d3 31. Rg7+ Kf8 32.Rh7 (not 32.Qxh6 Qd4+ 33.Kf1 Qxf6+ and Black wins).

[A2] 30..Qf8 31.Rg7+ Qxg7 32.fxg7 Kxg7 33.Qxd4+ Kh7 (Kf7/g8 34.Qc4+) (Kf8 34.Qf6+) 34.Qc4 eventually unblocks c.

[A3] 30..Qd5 (mate threat) 31.f7+ Kf8 32.Qxh6+ Kxe7 33.f8=Q+ and White mates: Ke6 34.Qxg6+ Kd7 35.Qge8+ (haha -- a disambiguator on a Q move) 36.Kc7 Qc8#.

So Black can't take the B. White threatens 30.Bxf7+ Kxf7 31.Re7+, so Black must defend f7.

[B] 29..Be8 31.Qxh6! too many mate threats: Qxf6[] 32.Rxe8#.

[C] 29..Ra7 31.Bd3 Qf8 (else Qg3/g4+ mates at g7) 32.Qf5 .

  jahhaj: I went for 29.Bxg6 fxg6 30.Rf7. I didn't calculate much further but it seemed a winning attack. For some reason 30.f7+ Kf8 31.Qxh6+ just passed me by, even though it's the more obvious sequence.

Both of them win.

  euripides: <I saw 28. Bxc6 Rxc6 29. Qxf6 > meaning 29.Qxh6 ? then 29...Rxf6. Oddly easy to miss.

  triangulation: i got this one exactly as in the game but was too lazy to analyse other variations especially for the defence. so i give myself partial credit.
Aug-25-07   Morphyisgod: Yes thank you <Euripides> i saw that after i posted it, so i deleted it.
Aug-25-07   Paladin88doug: The only move that shouts out to you. Bxg6...the point of the puzzle isn't to get the first move, cause I can normally find a tactic easily, considering the puzzles always revolve around tactics, not strategical choices. Those kind of puzzles would probably appear dry to most players, no real thrill and no bam-bam lay-the-smackdown kind of move like Bxg6.

  patzer2: The demolition of pawn structure with 29. Bxg6!! solves today's puzzle and puts the Black King on the run with White in pursuit for mate.
Aug-25-07   TheIrateTurk: A strange puzzle for me in that I was able to get most of the moves.

At first glance I immediately thought 29. Bxg6 followed by 30. f7+

I loaded the solution to check if I was correct, and when I found I was, I was able to predict what the next moves would be.

So I didn't predict 6 or 7 moves with grandmaster foresight, but I'm happy with myself :)

Aug-25-07   Monkey King: I saw Bxg6 followed by Re7 which dosen't seem to have any defense for black so stopped there.

  patzer2: If Black plays 30...Kg7, then 31. Re8! wins.
Aug-25-07   psmith: <zndprx>: On your suggestion of 29. Qd6 Qxd6 30. cxd6 simply 30... Bd7 is good for Black: the d-pawn will fall.

  fm avari viraf: The only move that comes to my mind is 29.Bxg6 fxg6 [ not ...Qd5 then 30.Qb8 wins ] Here, there are two main lines, first one is 30.f7+ & the 2nd one is 30.Re7 & the latter is my choice as it invades the 7th rank as well as threatens to mate. Here, Black will have to part with his Queen to avoid mate but the ensuing end game White's Queen Vs Rook + Bishop is a clear win for White.

  aragorn69: It seems nobody gave the following (simple) variations yet...

a) 34.-Kf7 35.Qh7+ Kf6 36.Rf1+ Ke6 37.Qf5+ Ke7 38.Qf8 mate (thx to the d6-pawn!)

b) 36.-Qd7 37. Qe5+ Kf3 38.Rf1 mate (thx to the h3-pawn)

Aug-25-07   soberknight: This seems to be a common problem with me: I start the Bxg6 analysis, then after a few moves - actually at Qxh6+ Kxf7 in this game - I say, "Nah, there's no point." If I had bothered to carry on the analysis five moves longer, I should have found the mate.

  An Englishman: Good Evening: Perhaps this was a bit too easy for a Saturday--I saw both the actual game variation and the line found by <psmith>, <RandomVisitor>, et alia.

Then again, judging the difficulty of a combination can't be much easier than solving one.

Aug-26-07   Fezzik: I was asked why I thought 29.Qh6 was reasonably. I saw 29.Qh6 Qf6 30.Bc6?! Rc6?? (30..Qc6!) 31.Re8. I don't think White is actually losing the position after 30.Qc6, but he certainly isn't winning either.
Aug-26-07   cheski: As regards the rather superfluous overly deep analysis into 30.f7+ versus 30.Re7, several quotes seem applicable:

Kasparov, in 1989, when after winning the world cup, he was questioned about a few opportunities missed:

"I showed my superiority...I was not forced to show my best" (Don't you just love this Aries!)

Then the opposite view:

"If you find a good move, look round for a better one."

Well, yes, but...What if you have already found a very very good move? Like here in this game.

And it seems unnecessary to look a gift horse in the mouth.

Far more interesting is to see what would have happened if Black had postponed his move 27...h6, and got rid of the dangerous white Bishop on =e4= first.

Aug-26-07   znprdx: thanx <psmith> like I said I maybe I should give up Chess - I kept seeing the impossible like rooks becoming queens on the 8th rank :)
Aug-26-07   znprdx: <cheski:Far more interesting is to see what would have happened if Black had postponed his move 27...h6, and got rid of the dangerous white Bishop> Well 28.Qh6 Qf8 29.QxQ KxQ 30.RXB now if Rd7 31.c6 and what do you see now? White should win easily....(since now the Black King can be mated on the d file in certain lines)
