Fruit is not a bean counter engine.
Fruit2.2 is one of the best engines.

It's king safety can be improved but it is wrong to say that it has no king
safety

Fruit2.2 even can find b3 after enough time and here is the proof(I guess that
Fruit2.0 or Yace are going to fail to find that move even after an hour of
search)

They cannot see that black is better even 4 plies later after 19...b3 20.axb3
