One usually stop the PVS search and use the result of the previous finished iterative deepening result. Remember that after you decide to stop the search you have also to stop saving killers, sving info to transposition tables and so on. One thing that has not been mentioned is that if the best mov...

I was wondering what methods people use in distinguishing between between sacrifices that appear to lose material but should not be reduced and bad moves which do lose material and should be reduced.

And I guess that it costs little more to make it than to make a 10 TB SSD. The fact tha...

The trick is to use second counter. for IO, I'd use a separate thread (main thread IO, search in a separate thread for the timeout, however, I'd still use polling I use one thread for input which blocks and one thread which waits for an input line, a search result, or a timeout.
