Congratulations to two Illinois players, David Sye and Terrence Aguinaldo, who tied for first in Class D with 4½-½ scores. (Sye's prize was limited to $500 because he had recently had a rating more than thirty points over the class ceiling; Aguinaldo won a full $1,000.) Another local player, Ga Luang Liu, shared third place with Hongbin Chen of Michigan and Sean Cramer of Ohio: each won $166.67.
(David titles his post "A complicated endgame position from the Chicago Class," but really, the position is easy if you've taken the time to learn some basic tricks--and there are several cute finesses in this simple-looking position. There might even be lines that David correctly doesn't mention because they're not Black's best try, but are still worth looking at....)
Class D crosstable is here!

Black can try to win with 1...b4 (1...Kf6 2.Ke4=) 2.axb4 (forced) a4! (2...axb4 3.Ke4=), when White's king is outside the square of the pawn. However, White still holds the draw with 3.b5! (not the immediate 3.f6+?? Kxf6 4.b5 Ke6 0-1) a3 4.b6 (4.f6+ also draws) Kd6 (4...a2 5.b7 a1(Q) 6.b8(Q)=) 5.b7 Kc7 6.f6 a2 7.f7 a1(Q) 8.b8(Q)+! (8.f8(Q)?? Qf1+ 0-1) Kxb8 9.f8(Q)+.
Hmm, not so simple, since the try 1...a4 (analyzed by Sye) never entered my mind.
