Hi Tibono,

this is a very cool short aproach about a proxy engine. I worked on the same years ago to fix a blunderproblem for the DGTplasticwaste.
If you want a engine that play's alway's on your own level, you must search for a move in some variant's that plays close to equal. The effect is a curiously playing engine that always puts you in the endgame, no matter how badly you play.
