Thanks Clement, though I am sure you could have found the same moves to win the endgame as I did.
Yesterday was another fun game, a double-edged Nimzo-Indian Defence. It started fairly innocuously, but soon got into a very complex position where both sides have many ideas. I won the exchange for a pawn, then chucked the exchange back, finally managing to draw the ending.

Today was tough because many players got into good positions but then messed up, which can be hard to get over. Still, with three rounds left everyone can still post a decent score.
I also note that Jonny and Shivan had a decent time of it down in Gatwick - Jonny scored 5.5/9 in the all play all and the highest rating performance of that group.
There have been some really interesting games at this tournament, with plenty of good play by the Scots, which bodes well for the future.
