I agree.  What I want to try is to prune moves semi-randomly.  Any move can
theoretically be pruned, but the probability of pruning will be bigger for
moves which tend to be difficult to see for humans.  For instance, I want
the probability to be higher deep in the tree than close to the root,
and to be big for moves with negative SEE values.  Long moves should be
pruned more often than short moves.  The computer will still be tactically
strong, but occasionally play incorrect combinations (because it overlooks
some tricky defensive move) or allow some tactical shot for the opponent.

Experimenting with different types of "blunder styles" could also be
interesting.  You could make an optimistic style by pruning more moves
for the opponent than for the program, or a pessimistic style by pruning
more moves for the program and few for the opponent.
