In Week 2 Arizona battled to a 2-2 tie with the Philadelphia Inventors.  We used a Tucson squad again.

The first game to finish was Adamson-Gorman, when white was up a pawn but black had enough positional compensation.

Next was Bartell-Ginsburg where the Philadelphia player left his king in the middle and got into a lost ending.

After that, Atoufi had a good game against Dehmelt with the bishop pair and a strong passed e-pawn, and in fact Dehmelt offered a draw, but Atoufi had the sound off and did not know.  He probably would have declined anyway.  At any rate, Atoufi misplayed and Dehlmet won a close endgame by one tempo.

Finally Molner and Erenburg agreed to a draw in a completely equal rook ending that came out of an Evans Gambit.

18.Bd2 Ba6+ 19.Kd1 Be7 20.f4 Ng4?!  The obvious 20… Nd3 was by far the fastest. White cannot untangle.  The text wins too.

21.Ke1 Bb7 22.h3 Nh6? For some reason, I overlooked 22…Nf6! 23. Nxf6+ Bxf6 and with both the R on a1 and the B on g2 hanging, black wins after 24. Bxb7 Bxa1 with an easy win.

 23.Rg1 Nf5 24.Nf2 Bxg2 25.Rxg2 Rbc8 26.Ra2 h5 27.g4 hxg4 28.hxg4 Nd6 29.Bb4  More prudent is g4-g5 shutting out the Bh4 possibility.

Bh4 30.Bxd6 Rxd6 31.Rd2?  A losing blunder.  Black concludes with some simple moves.   However it is difficult.  31. Ke2 Bxf2 with the idea of Rc3 is crushing.

Rc1+ 32.Ke2 Rxd2+ 33.Kxd2 Ra1 34.Ke2 Bxf2 35.Rxf2 Rxa3 White resigns 0-1

The text is a funny looking move committing both rooks on semi-closed lines.

Weirdly since white’s pawns are so weak and he is tied to the a-pawn there no way to make progress in this position.  If only the king side pawns could be mobilized but there is no way to arrange it.

White has a terrible game.  Somewhere in here, white offered a draw but black’s sound was off and he did not hear it.  ARGH!!!!

32.Rd1 h5 33.Bf3 h4 34.Ne2 Bb4 35.Rd5 Bb1 36.Rb5 Bd2  This bishop can be usefully used on the e5-b8 diagonal instead helping contain white’s only source of play, the queenside pawns.  

37.a3 Bd3 38.Rd5 Bc2 39.b4 f5 40.c5 g5 41.h3 g4??

Black blunders and loses an ending by one tempo.  Agonizing.

Arizona should have won this match.  ARGH!!!!
