Materialism

My position seemed worse in my first thirty minute game on Instant Chess (Chess LIVE--see "More iPhone Chess Apps"). I have White.

Black to move

My opponent went for the win of a pawn.

26...Nc4?!

26...Rac8, activating the other rook made sense positionally.

27.Rd7?!

Of course, with 27.Rd5, we would be exchanging pawns.

27...Nxb2 28.Rb1 Na4?

It is better to defend the knight. 28...Re2, when Black maintains an advantage.

29.Rbb7=

From a bad position, I have achieved equality, although I was a bit overconfident. My opponent's subsequent play suggests that either he also thought White had a clear advantage, or that he failed to comprehend my threats.

Black to move

29...Rf8 30.Bd6 Rfe8??

30...Rfd8! and White's pigs are blind (see Edward Winter's Chess Notes 3494, and CN 5160--both reposted at ChessBase News "Unsolved Chess Mysteries" [26 December 2007]). 31.Rxf7 Rxd6 32.Rxg7+ Kh8 33.Rh7+ Kg8 34.Rhg7+ The two pigs can check and check and check, but they cannot find checkmate.

31.Rxf7+- Re1+ 32.Kg2 c4?

The prophylactic 32...Kh8 avoids immediate checkmate, although Black still is lost.

White to move

Black grabbed material, and then attempted to protect his material gain. Now, as a consequnce, White has checkmate in three.

33.Rxg7+ Kh8 34.Rh7+ Kg8 35.Rbg7#
