Nf3 Nf6 3. e3 Bg4 4. c4 e6 5. Qb3 {Instructive. Bg4 followed by e6 has left the b7 pawn undefended so Andrew immediately puts pressure the black queenside and breaks the pin on the knight on f3} b6 {Notice now that the white sqaures on b7, c6 d7 are weak - that wouldn't be an issue if the black bishop could cover them} 6. Ne5 {Immediately pressuising the weak light squares and hitting the bishop on g4} Bh5 7. Nc3 c6 8. cxd5 exd5 9. Bd2 {Notice how efficiently Andrew develops his pieces and builds - soon the rook will come to c1 increasing the pressure on black's queenside} Ng4 $2 {No! Black is behind in development so the last thing he should do is move a piece twice! Bd6 was more sensible} 10. Nxg4 {Simplest. 10.Nxc6! is also possible but is unnecessarily complicated} (10. Nxc6 Nxc6 11. Bb5 Rc8 12. Nxd5 Bd6 13. Rc1 Qh4 14. g3 Nxh2 15. gxh4 Nf3+ 16. Ke2 Nfxd4+ 17. Kf1 Nxb3 18. axb3 Kd7 $18 )Bxg4 11. Rc1 {Following the plan} Be7 12. Bd3 O-O 13. h3 Be6 14. Ne2 {The pressure on the c6 pawn makes it difficult for black to develop his knight} c5 {Best. Notice that this threatens 15...c4 forking the Q and B } 15. dxc5 {Now black had 2 ways to recapture. Bxc5 leaves black with an isolated d-pawn. bxc5 (best)leaves him with "hanging pawns" on c5 and d5 } d4 $2 {Black chooses a 3rd way by uncovering an attack on the queen with his B on e6} 16. Qc2 {... which Andrew calmly side steps with his own attck on h7} g6 17. Nxd4 Bxc5 $2 18. Nxe6 $1 fxe6 19. Be4 {Notice that black has still not developed his queenside and now pays the price. Actually white's position is so good that he could even play 19.Bxg6 here} (19. Bxg6 $1 hxg6 20. Qxg6+ Kh8 21. Bc3+ )Nd7 20. Bxa8 Qxa8 21. O-O Nf6 22. b4 Be7 23. Qc6 Qb8 {This loses outright but the alternatives result in the queens coming off and without any chances} 24. Qxe6+ Kh8 25. Qxe7 Ng8 26. Bc3+ 1-0
