1. d4 e6 2. c4 Nf6 3. Nf3 b6 4. a3 Bb7 5. Nc3 d5 6. Bg5 Be7 7. Qa4+ Qd7 8. Qc2 very sensible, I think White is slightly better after this 8... O-O 9. Bxf6 Bxf6 10. cxd5 exd5 11. e3 c5 12. Rd1 c4 13. Be2 Qe7 14. O-O a6 I'm not convinced by Black's position - White should play for the central break with Nd2, Bf3, e4 type ideas 15. b3 but instead tries to mix things up on the Queenside - now things get interesting 15... b5 16. bxc4 dxc4 17. e4 g6 17... Qxa3 is the pawn poisoned - Fritz doesn't think so, I just assumed it might be 18. e5 Bd8 -1.00 Fritz at 11 ply 18. e5 Bg7 19. a4 b4 20. Ne4 b3 seems best, c3 also needs consideration 20... c3 21. Bc4 21. Qb1 21. Nf6+ Qxf6 22. exf6 bxc2 23. fxg7 Re8 I'd missed this when I played b3, after my originally planned Kxg7 Black is only slightly better(23... Kxg7 24. Rc1 Be4 25. Ne5 Rd8 26. f3 Bc6 27. Nxc4 Rxd4) 24. Rd2 Be4 25. Bxc4 Rc8 26. Ne5 Nc6 27. Nxf7 Na5 and wins 21... Qb4 22. Rc1 Bd5 23. Nc3 Be6 Bb7 repeats and draws 24. Qe4 obvious but ... 24... Bh6! eventually preferred by Fritz at 13-ply 25. Qh4?! but Black appears to be much better in all lines so why not try the mating attack 25. Qxa8 Bxc1 26. Rxc1 b2 25. Rce1 Qxc3 26. Qxa8 b2 27.
