I ignore this problem. My engine will not be able to play 5 second games with ponder on without much losing on time. I don't care. I call inpu_available about 10 times per second. For this, the overhead is practically zero. Perhaps calling it all 100 nodes would still give no significant overhead (I did not measure or try it, because I was not interested yet in that fast time controls - but I might try soon). Then, this should be enough for 5 second games. The multithreaded approach should have no overhead at all (just checking one variable each node). Regards, Dieter
