OK – first, I’ll browse through the Summary for some tips – I want to find the best moment to deviate from her favorite line. I usually play 8. Be2, but now I’ll follow recommendations for club level players: <click> 8. Bd3… Let’s say she plays <click> 8… Ng4 <multiple clicks follow> 9. Nh3 Bc5 10. Nc3 O-O 11. O-O f5 12. Be2 Rb8 13. Kh1 Qe7 14. f3 Nf6 15. b3 Bb6 16. Qe1 Qd6 17. Bb2 Bc7 18. Na4 and now I have an extra pawn and Black has insufficient compensation for it.
By choosing an entirely different move, I’m surely going to surprise her. I might even be acting surprised, myself – mind games are fun, don’t you think?
