Temporary revert "captures pruning" due to an assert

Browse source 
In debug run with 2 threads it happens to be following
assert after some minutes:

assert(value > -VALUE_INFINITE && value < VALUE_INFINITE);

in search(), line 1615.

I am not able to understand why, anyhow reverted for the moment.
