Once I started thinking about how to get the bishop away from defending h3, the moves seemed to flow naturally - so for me this was much less hard than yesterday. Playing through the game I spent most of it thinking that white was winning, until suddenly the black pieces formed a vice. Very elegant.

33...e2 34.Bxe2 34...Rh3+ wins the Knight

or 33...e2 34.Rxe2 Bxc4 also wins a piece

*****
PM: I was wrong about Black winning apiece after 33...e2 34.Rxe2 Bxc4 when White is forced to surrender the exchange (not that it saves the game)

33 ... e2. 34 Rxe2 loses the exchange, while 34 Bxe2 loses the knight and 34 Bg2 loses the c-pawn. But in a couple of those lines it looks like White can recover material.

33 ... Rf8. But I don't see how to punch through after 34 Bg2 and 35 Rxe3; the rook on the 7th doesn't seem to accomplish much.

<33 ... e2>

The pawn is immune from capture...

34 Rxe2 Bxc4

34 Bxe2 Rh3+

<34 Bg2 Rd8!>

Black's mobile rook out-manouevers white's static pieces. The pawn is still immune from capture as black is now threatening Rd3+! winning Nb3 and <34 Nc1> results in <34 ... Rd1> still winning the knight! Also and probably even more importantly the black rook is now covering the knight's only decent escape square too!

35 Rxe2 Rd3+

<34 Kf2 ...>

What a miserable choice! Pg4 is now no longer attacked and so Be6 is free to attack itself.

<35 ... Bxc5>

Black can't go down this route either!

Man walks into an expensive restaurant and orders a plate of Emmental. I suppose he ordered other things before the cheese board, oh I don't know, let's say he has the pate and melba toast for a starter, a nice pan-fried sea bass for mains and a chocolate tart for pud. And then he orders the aforementioned Swiss cheese. As you do.

The waiter brings along a plate of cheese, some wafer biscuits and a grape. Artfully arranged on a wooden board with a specially carved niche wherein for the grape to sit without undue roll-away-age in the transportation from kitchen to dining table.

"What is this?" demands the man in a fit of indignant foodie rage. "This is not Emmental! The holes are too large."

The waiter has been schooled in the art of "the customer is always right". He smiles benevolently at the diner.

White threatens 34.Rxe3.

The white bishop protects h3 and the pawn on c4, and the white knight is defenseless. These details suggest 33... e2:

A) 34.Bxe2 Rh3+ 35.Kf2 Rxb3 - + [N vs 2P].

B) 34.Rxe2 Bxc4 and White loses the exchange or a piece.

C) 34.Bg2 Bxc4

C.1) 35.Rb1 Bxb3 wins the knight (36.Rxb3 e1=Q+).

From this position (after 33...e2 34. Bg2), my 34...Nf4! and <gofer>'s 34...Rd8! are both winning. Fritz 12 @ 22 depth, on a dual core processor running at 2.1 GHZ, gives 34...Nf4! as slightly stronger than 34...Rd8!:

1. (-6.33): 34...Nf4 35.Nc1 Bxc4 36.h3 gxh3 37.Bf3 h2 38.Rh1 Rd8 39.Nxe2 Nxe2+ 40.Bxe2 Bxe2 41.Rxh2 Bd1 42.Rg2 Bxa4 43.Kf3+ Kf6 44.Rb2 Ke6 45.Ke3 Rh8

33...e2

34.Bxe2 Rh3+ followed by 35...Rxb3

34.Rxe2 Bxc4

From http://en.wikipedia.org/wiki/Emment...:

"Emmentaler or Emmental is a yellow, medium-hard cheese that originated in the area around Emmental, in Switzerland. It is one of the cheeses of Switzerland, and is sometimes known as Swiss cheese..."

"Failure to remove CO2 bubbles during production, due to inconsistent pressing, results in the large holes ("eyes") characteristic of this cheese. Historically, the holes were a sign of imperfection, and until modern times, cheese makers would try to avoid them..."
