Sean Williams is pretty well known. He is organizer of the big London tournaments. Martin Birkhan is a strong player but doesn't play a lot.
20% increase in gammons while only costing a little more than 2% wins is not quite enough to make the attacking play correct here. The anchoring play protects an efficient cube while the attack loses cash if both enter and loses a correct cube completely on 3 entering doubles while overshooting the take drastically if none or just one enter.
