15.Bf5!
This was the position I found myself in from the opening in my round four game against Mark Quinn when we, along with Mark Heidenfeld, were both on full points. I felt the opening had gone fine for me as the Knight on d2 is less effective than it would be on C3 against the hanging pawns, however I now failed to appreciate the strength of Whites last move and went wrong with a careless move.

Now White has a clear edge

Actually might have been fun in a rapidplay game but it is bad for Black.]

Another natural looking, but weak move [18...Qe7!
And Black is keeping his disadvanate to a minimum]

White has a clear advantage but Black is still very much in the game. Whites next move allows Black to turn the tables on him.

30.bxc6?
[30.Be5
And White is only slightly worse]
30...Bc5!
White is in trouble
31.f5
The rest of the game was in mutual time trouble where Black missed chances to play the most ccurate moves early on and win fairly easily. Instead Black has to keep his best till towards the end and squeeze out a win in a rook ending. [31.Bxc5
