Standard Chess #18: Jonchess vs. IM Bartholomew (Sicilian Defense)

In the Kan Variation of the Sicilian (1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6) Black develops flexibly - something that can frustrate an Open Sicilian player! Here my opponent makes a stereotypical mistake with 6.Be3, and though he minimizes the damage immediately thereafter with 7.a3, his position only becomes increasingly questionable.
