Nov-11-09  YouRang: I'll add my name to the list of those who thought 34.Bh6 was good.

Granted, I didn't see the strength of 34...f4!, which not only interrupts Qg5+, but also turns ...Bxf2+! into a deadly counter attack by enabling ...Qg3+.

However, now that I do see it, it seems that 35.Bxf4 scoops up a pawn and saddles black with an ugly king position.

Nov-11-09  ruzon: I considered 34. ♗h6 first like many before settling for 34. ♗c3 and winning the Exchange. I think 34...♔h8 is the best refutation of the former.
Nov-11-09  JuliusCaesar: Bc3 must have come as a shock to Fish! Imagine leaving the board, going for a stroll to stretch your legs, feeling pretty okay about your position and then finding a white bishop on c3 when you get back -:)
Nov-11-09  Marmot PFL: Eventually I realized that white's main threat was Qg5+, then found the move Bc3 to make it happen.
Nov-11-09  WhiteRook48: I saw something of a possible Qg5+ so I played 34 Bc3 I looked at 34 BxN first though
Nov-11-09  ComboKal: <eblunt> In his main line, <gofer> had played <34. ...f4>, not f6 as you have it.

So, now, if you try to play <35. Qc6>, you get burned after <35. ...Bxf2+, 36.Kxf2 Qg3+!>

Nov-11-09  GaeBulg: Ugh, I was thinking Bh6 threatening a mate and forking the knight after moving Qc6. I assumed that the only defense after Bh6 was Bf6 to prevent the queen from going to g5 to deliver mate, but I missed ...f4 which puts all my plans to shame...all i get out of that is one free pawn >_>
Nov-11-09  YouRang: <ruzon: I considered 34.Bh6 first like many before settling for 34.Bc3 and winning the Exchange. I think 34...Kh8 is the best refutation of the former.>

Actually, things still go downhill for black pretty rapidly after 34...Kh8 35.Qg5 (threat: Qxd8#).

Using the link in my last post, Crafty playing Black continued against me: 34 Bh6 f4 35 Bxf4! f6 36 Bxd5+ Qxd5 37 Qc7 Rd7 38 Re8+ Kg7 39 Re7+ Rxe7 40 Qxe7+ Qf7

Dreev-Fish Bh6 var 41? My first instinct was to exchange Queens but, surprisingly, Black's better King position appears to balance the Pawn deficit. I could not win the Bishop ending. I then tried the Queen ending, reached after 41 Bh6+ Kg6 42 Qe4+ Kxh6 43 Qxd4 Kg6. Crafty inexplicably then exchanged into a lost King and Pawn ending after 44 Qe4+ f5?

I only considered 34 Bc3 out of desperation to find a move that I had been told existed. And even then I had to "force" myself to put a piece where it could be captured three different ways.>

Amen -- I found Bc3 usinge a combination of the cheezy way, and the classy way... the cheezy way is: "it's a puzzle, I'm going to sit here and find a winning move if it takes all night' ... the classy way: "let's analyze the position and see what there is to exploit"... this led to seeing that Qg5 check-forked Black's rook and this meant all I needed to do was get my bishop out of the way."

Buuuut, no full point for me because I failed to consider Be3. I thought his B would go desperado with Bxf2+

Nov-11-09  ComboKal: <David2009> Thanks for the link. Yet another great chess site that I've added to my favorites!

After 35...f6, you might try returning the bishop to h6: 36.Bh6 to set up nasty threats against the king in conjunction with Qc6 (hitting e8) or Re7.

Nov-11-09  WhenHarryMetSally: I think 20...........Qa4 was a big mistake by black. couldn't dig himself out of the hole after that
Nov-11-09  SufferingBruin: 1000 rating, trying to get higher.

White has the two bishops. Black has doubled pawns, one of which is for the taking. Development is even, though black's pieces are more advanced, albeit two are hanging (queen and bishop). White has major pieces on two open files. It's not clear who has the initiative. The board is as open as a national park.

And after noticing all of this, I'm still looking at all the damn pieces and trying to figure out moves. I keep waiting for the above information (Silman's list of imbalances) to suggest a move or a plan but I'm thrown by the fact that one move is all that is needed. I gave it a few minutes and decided on Bh6. I know it can't be that easy.

(Later) And it's not. The difference between the player I am and the player I want to become is this: the queen can attack both rook and king on the g5 square and I didn't see that as a possibility. In my defense, the bishop was in the way...:)

Nov-11-09  MaxxLange: <SufferingBruin> I'm rated 1675, and I totally missed the idea too. Since the Bishop was blocking the Queen from going to g5, I never asked what would happen if she went there.

Don't beat yourself up for not finding it, just learn from the pattern, and keep forging ahead.

The daily puzzles here have been getting more difficult over the last two years or so, also, in my impression. At 1000, you're now doing very well if you can get a Tuesday puzzle.

Nov-11-09  YouRang: <SufferingBruin> I'm unrated. Anyway, I did see the idea of Qg5 forking the king and rook, and that was my motivation for 34.Bh6 -- to get the bishop out of the way (and create mate threats along the way at g7 and along the back rank).

I had glanced at 34.Bc3, but only long enough to think: "that's no good; I'll win black's rook with Qg5+, but then black will get the rook back with ...Bxe1".

Obviously, I ignored the fact that after Qg5+, the black king cannot move to a square where he will not be in check when I take the rook. Either that, or he must play ...Bg7, which removes the threat on my Re1.

Not carrying an idea far enough has been a stumbling point for me in many, many puzzles. :-|

Black is down a bishop in this diagram, and can't recover it.

If 35...Rxd5?, 36.Qxe3 (threat: Qe8#) f6 37.Qe8+ Kg7 38.Re7+ Kh6 39.Qh5#

Exchanging queens just leads quickly to a lost endgame: 35...Bxc1 36.Bxb3 Bh6 37.gxf5 Rd3 (hoping to pin bishops) 38.Re8+ Bf8 39.Rc8

Nov-11-09  SufferingBruin: <MaxxLange><YouRang> Much obliged to you both.

  Once: To everyone who missed this puzzle - don't despair! This was a tough wednesday because the key motif (queen fork on g5) was pretty well hidden.

<SufferingBruin> I am not sure that Silman's imbalances will help here. Although they are an excellent tool for strategic planning, they are not so hot for spotting tactics.

Here's what I do in a real game. When my opponent's clock is running, I try to stop myself from analysing varations. After all, this could be totally wasted effort if he plays an unexpected next move! Instead, I look for strong and weak points in both my pieces and in my opponents. Which of my pieces would I like to improve? Where is my attack coming from? Which pieces do I want to swap off? Am I winning or losing? And the same for my opponent. That sort of fuzzy imprecise thinking.

And in this type of general thinking, you are allowed to move the pieces around in illegal ways - in your head at least. It's a bit like doodling or daydreaming. What would happen if I could hyperspace my queen to g5, ignoring my own bishop that is sitting in the way?

When we start a puzzle, we don't have the luxury of having seen the position unfold move by move. So while we have an advantage over the players cos we know it's a puzzle, we also have a big disadvantage. The players will have had much more time to build up their understanding of the strengths and weaknesses of the board.

So one way to start a puzzle is to imagine that you are in your opponent's time. Don't feel that you have to find a specific move straight away. Instead, look for strengths and weaknesses and daydream about fantasy moves.

In today's diagram, black's weak points include an exposed king and an unprotected rook. That ought to lead us eventually to Qg5+. And that in turn should point us to the need to move the bishop. And where to put it? The most aggressive move is to threaten mate or win of material, so how about Bc3 to stab at the black queen?

But having said all that, I still think that this was a toughie!

Nov-12-09  MaxxLange: I try to focus on just seeing the position, not even thinking about it, when my opponent goes into a long think. Look at every piece, and see all the squares it can move to.

It's easier to say than to do, though....

Nov-12-09  eblunt: < ComboKal: <eblunt> In his main line, <gofer> had played <34. ...f4>, not f6 as you have it. >

Gofer gave ♕c6 in both his 34 ... f6 and 34 ... f4 lines, and it wasn't clear which line his ♕c6 disaster referred to. Against 34 ... f6 ♕c6 is fine and clearly winning IMO, against 34 ... f4 White simply wins a pawn with 35. ♗xf4, and an clear pawn advantage, though by no means a clear win.

(all this refers to 34 Bh6 for the sake of clarity )
