13. Re1 Nxd3 14. cxd3 {All of which has been seen before. This and similar
positions are deemed about equal, and some lines of this opening have been
analysed incredibly deeply.} Nb7 15. Rxe5 Bf6 16. Re1 Bd4 17. Rf1 Nc5 {just a
few moves later things are looking bad for White, having spent three tempi on
grabbing a second pawn but otherwise going backwards. It is now hard to find
good moves for White and easy to find them for Black!} 18. Ne2 (18. Na3 {
was perhaps the best course}) 18... Nxd3 19. Nxd4 Qxd4 20. Qe3 Qd6 21. Nc3 Ba6

on the e-file and playing Re1 2) playing Rg6} 25. a4 Rae8 26. b5 Re1 (26... Rg6

Re7 34. Ra1 Rd7 35. Ra2 {after a complicated sequence of play the position has
stabilised and Black is clearly a lot better. She is a pawn up, the a-pawn is
a major asset, and the bishop is better than the knight. This is certainly
not an easy conversion, particularly as the a-pawn is currently pinned down,
and Petra only had a minute on her clock.} a5 {this move must have come as a
great relief to Ian} 36. Rxa5 Qxd2 37. Qxd2 Rxd2 38. Ra2 {Perhaps Petra had
overlooked this X-ray defence of g2. I think this position must be drawn with
a little care by White. Certainly Ian drew it without any hiccups.} Rd3 39. Ne2
