Yes, but they can be very tricky. - You have to take care of extensions specially thread extensions after the move are difficult to find (in my program) - You can only cutoff if the score comes back >=beta so you have to compare against <=-beta and it has to be a BELOW_ALFA or EXACT node (or something like that ) And probabely more, but by then I kicked them out already. cheers, Tony >Do we need to store additional stuff in the hash table for ETC? >Are there any freeware engines with free source code that use ETC? > >Thank you >Alvaro Cardoso
