I always dreamed of such a engine. I also asked Roberto Punter to make Vitruvius. But it turned out to be crap. I always run Stock on Aggressiveness 200 which solves most of the positional tactical shots. Your Idea is warmly welcomed.lech wrote:Don't worry Om, I will do it, like you wish.Master Om wrote:Yes.

Your help is invaluable. Many thanks again.

Set Cowardice to 200 too or both x 150. Try it! (on Sting too).Master Om wrote: I always run Stock on Aggressiveness 200 which solves most of the positional tactical shots.
Damn!!!. Never tried this idea. Ok i will. I am going to use sting in playchess. Lets see whats happening. But Increasing Cowardice doesn't make any sense.lech wrote:It would be a Holy Grail.Master Om wrote: I always dreamed of such a engine.Set Cowardice to 200 too or both x 150. Try it!

Cowardice is only a strange name. I know code of Stockfish. Trust me!Master Om wrote: But Increasing Cowardice doesn't make any sense.
And i thought ts something related to to fear of making sacs or risk taking. I make it zero as i think it will not be coward in attacking.lech wrote:Cowardice is only a strange name. I know code of Stockfish. Trust me!Master Om wrote: But Increasing Cowardice doesn't make any sense.
