I find this idea very exiting! My understanding (but I am not an expert) is
that so far such ideas goes somewhat against the provisional wisdom. However
machines are getting so fast and there playing strength so hight that is
certainly believe Thom Perrys idea could be extremely successful. The strong
chess computers still remarkeble weak if judging the value of an attack.
We one could use half the computation time in isolating and investigating
sacs (and other unusual moves) which leads to unbalanced positions
modern programs could get a quantum leap forward in playing strength.

The whole idea of testing conjectures, like "does this attack works",
"is it worth winning the pawn" etc. seems very sensible given the enormous
speed and strength of modern computers. Did anyone try to implement
Thoms Perrys idea?
