As far as I know Fruit2.1 already has too agressive extensions because it extend
every check and every single reply by a full ply.

Using this illogical extensions it can see the famous mate in 30 in Ed's page in
depth 1.

I also think that Game/30 minutes for slow PC is equivalent to game/1 minute on
today PC and the top programs at game/1 minutes are also the same programs
so I do not think that there is going to be difference because of search that is
not good for slow pc.
