Well I did but was just a little late. Also the PGN viewer above is blocked from my work so I can't even see what Ian has written. But a bit of duplication won't hurt - here are snippets from my PGN file:
I wasn't at the club for this game but as soon as I received the PGN from Ian I remembered his game from several other club players. I've seen the position at move 13. Qd4 about 4 times with Anthony as black so he happily invites opponents. Yet it bugs me because either way you look at it, 9. ..Kf8 or 9. ..Kd7 to me blacks position just seems like a real up hill battle. His king is vulnerable in the middle of the board and it seems white is a lot more comfortable with good room to gain initiative, or even an attack on the black king. However to be more objective we are talking about Anthony here who has probably looked at every single nook and cranny in these lines.
Surprisingly after ..Kd7 engines get confused with the position and give a better evaluation straight away around a whole pawn, but as you play on a couple of moves this jumps back down to drawish again. This demonstrates how complex and unbalanced the position is. The following lines are generated using Houdini 3 i5 quad core machine.
