Jan-15-16  morfishine: <28.Bxg6>
Jan-15-16  wooden nickel: Maybe this is the case <My first intention wasn't to win the game, I just wanted to sacrifice a piece. -Steinitz>
Jan-15-16  Kasparov Fan: Not so difficult when you hear what the position is saying, If you are going to break black's defense you will have to sack the bishop at g6 as any other plan is too slow and gives black time to regroup.
Jan-15-16  Cybe: 29… Rh7 is OK – strong russian engines are giving about +0.80 for white.
Jan-15-16  stacase: The Bishop sacrifice was obvious, but 30. Rook b7 was not.
Jan-15-16  mel gibson: I saw this one in only a few seconds.
There was no other move for white
- only a Bishop sacrifice.
Jan-15-16  jith1207: Not sure if this is easy for Friday. Sure, it is easier to find the bishop sacrifice. But if the subsequent tricky moves are not found, situation might get upside down easily or at least could lead to perpetual as <JimFrom Providence > points out. The ending was tricky for me, I failed but that was a good lesson for such a position with the king hanging behind the bishop supported by his queen versus the opponent queen and a rook.
Jan-15-16  EIDorado: @ Jimfromprovidence I missed the perpetual check. 29. ... Rh7 is indeed the strongest move.
Jan-15-16  YetAnotherAmateur: The sequence 28. Bg6 hxg6 29. Qxg6 jumped out immediately, because it threatens Qxh6+, Qxf7, and Qxd6 (with a followup threat of Rb8-Rxb8-Rb8 winning the black queen).

Of course, black doesn't have to be so obliging as to let white carry one of those threats out, and can play Qf8 to defend all 3 of the attacked points. However, in doing so, she abandons the defense of b7, which is now left to the rook. White can now claim control of the 7th rank and threaten mate, and black is powerless to stop it in the end.

I can only claim partial credit for this one though: I saw the bishop sac and the trouble it created, but only got as far as seeing that white gets the material back and has a strong positional advantage after doing so.

Jan-15-16  dumbgai: The idea here is easy to see, but the specific tactics are not easy to calculate.
Jan-15-16  kevin86: White gives up a bishop for two pawns...then cripples his opponent with a lethal attack.
Jan-15-16  beenthere240: While the bishop sac is easy to spot since it is a puzzle, I found the Rook moves difficult to see. I sort of saw Rb7, but Rf7 and Rf5 escaped me.
Jan-15-16  RandomVisitor: The game line of 28.Bxg6 hxg6 29.Qxg6 is perhaps not best due to 29...Rh7.

Maybe 28.Rb5 Qg8 or 28.h5 gxh5 29.Rh1 or 28.R3b2 Qc7 are worth a look.

27.h5! Nf5 28.hxg6 is the way to do it.

  Jimfromprovidence: <gofer> <So I got the first 7 moves, but I am interested in comments from <Jimfromprovidence> about...

<28 Bxg6 hxg6>
<29 Qxg6 Rh7>
<30 Qxd6 Qf5>
<31 Rb8+ Bf8>

I wonder what the silicon monsters say to this pawn grab...

<32 Qxc5! ...>

White wins a fourth pawn for the bishop and also provides protection for its king>.

One logical continuation is 32...Rxb8 33 Rxb8 Rf7.

Yes, white wins a fourth pawn for the bishop but now Black has counterattacking chances. White has to retreat his queen to e3 or f2.

The position is unclear at this point.

Jan-15-16  jith1207: Thanks <Chris Owen>, I have always wondered what the maximum limit of a post could be here. It looks like 3000 characters would be the maximum from your first post. Yay!! I got something out of it.
Jan-15-16  LucB: That last move is a beaut'!

  gawain: The easy part was seeing the bishop sac. I did not anticipate 29...Qf8 (I assumed 29...Rh7). In the game continuation, white's rook's progress from b1 to f5 (moves 31-33)is marvelous.
Jan-15-16  stst: no picture, a locked and dull position. White takes advantage of the 7th rank, main line should look like this: 28.BxP PxB
29.QxP(takes R or B, but..) Rh7/Qf8 will protect
30.Rb7 and Black got a hard time defending another R getting to the 7th rank....
Jan-15-16  stst: < Yay!! I got something out of it.>

Would like to share the gem (out of "it"!?!)

Jan-15-16  jith1207: <stst> Just the word count., he he. Nothing much else to enlighten myself.

  Sneaky: I've always had a theory that Mr. Owen is transmitting secret messages to operatives overseas.

About the puzzle, a classic example of "first move obvious to speculate" but to see it through to conclusion requires a very strong player. I actually envisioned it all the way up to 31...Bg7 and tried to imagine a plan from there.

I thought maybe pushing the kingside pawns would win, any maybe that plan would actually work. They look scary as can be. But I totally failed to think of the very simple idea of Rf7-f5-h5 which wraps things up immediately.

Jan-15-16  Cheapo by the Dozen: I got it on my second try, not in fullest of detail, but in enough to play it over the board.

On my first try I tried to see how a slow build up vs. h7 while also keeping the b-file pressure on and potentially playing Rb8 could win, and I couldn't see how that would work.

Jan-15-16  transpose: I knew white had to sac, did not figure on black's 29 . .Qf8 as the best defense (I counted on 29 . . Rh7 when 30 Qxd6 should be sufficient with threats), and although 30 Rb7 seems (and is) best, it is white's 32 Rf7! and 33 Rf5! that impress me the most.
Jan-16-16  CHESSTTCAMPS: Material is even in this opposite-colored bishop middle-game, but it is obvious that white has a strong advantage with two distinct batteries pointing at b8 and g6. In particular, g6 is a juicy target, because the black king doesn't have much pawn shelter and it makes an excellent entry point for the white queen.

Therefore, 28.Bxg6! is almost a no-brainer:

A.28... hxg6 29.Qxg6 Qf8 30.Rb7! Rxb7 (Rf6 31.Qh7#) 31.Rxb7 Bg7 (forced) 32.Rf7 Qg8 33.Rf5! (h5? Rf8 holds) Qe8(/d8/c8/b8) 34.Rh5+ Kg8 35.Qh7+ Kf8/f7 36.Rf5+ picks up the bishop with check, winning.

A.1 29.... Rh7 30.Qxd6 (threatening both Rb8 and Qxe5+) is deadly

B. 29... Rg7 30.Bf5 with pawn plus initiative.

All I have time for....

Jan-16-16  CHESSTTCAMPS: Even trickier than it appears, as the extensive contributions have shown.
