Hi John
Effectively a6 is a bad move, although the pseudo position was complicated (Myrddin's merit), but a6 is losing, it seems an improper move by Pseudo, but neither will we take any merit from Myrddin's victory, must be there to win

The truth is that Pseudo is an engine that I like very much, an engine with a pretty good rating for the year it was developed (year 2005).
It is a pity that its author did not continue to develop this engine.
