Adjudication against Andrew Stone
Hi all
I have the following position which I think I should claim a draw on, despite Black being better. It is black to play and move:

I have done quite a lot of analysis on it, and here is some of it:
I think Black's best move is Bg5

In the main line of the above, I think it is a little too much if White can play for an endgame. I don't think Black is justified trying to claim a win via adjudication instead of offering to play on.
Anyway, Mike Jones may have to send this position off now to claim a draw.
