Re: Weak engine

Oh, Im still in the "no king safety" phase myself and it is glorious! On top of that my engine is currently tuned so he is not particularly fond of material and loves activity (people who faced him in his debut, HGM's tournament last Saturday, might agree) which makes it particularly entertaining to follow his games.

The following example was played today between my current version and a 3 week old version (which is still a bit materialistic). The position after 23.Nf4 is a thing of beauty imo =)
