I guess that limiting extensions is a possible direction for improvement.

The fact that Fruit2.1 solve the following mate in 30 in depth 1 means that it
does often useless extensions.

[D]5n2/B3K3/2p2Np1/4k3/7P/3bN1P1/2Prn1P1/1q6 w - - 0 1

I guess that using partial extensions can improve fruit and extending both
checks and single reply by a full ply is a mistake.
