1.d4 Nf6 2.Nf3 d5 3.e3 e6 4.Bd3 The Colle System, a perfect system for Purton, as it allows him to keep a draw in hand and still has some bite for the unwary. 4...c5 5.b3 Nc6 6.a3 a6 7.0-0 b5 8.dxc5 8...Bxc5 9.Bb2 Bb7 10.Nbd2 Rc8 11.Qe2 Be7 12.c4 By engineering this break Purton opens the position for his actively placed bishops, giving him a strong short-term initiative, while still keeping the pawn structure sterile against a higher rated opponent, and thus allowing a draw oppurtunity if nothing comes of his play. 12...bxc4 13.bxc4 dxc4 14.Nxc4 0-0 15.Rfd1 Qc7 16.Rac1 Nd5?!
