EPD-Test Arena Bug report

Post by Edmund »

Doing an Arena epd test with more than one avoid move together with an early cutoff criteria can cause false cut offs:

As in the following case, where I gave Glass 1min per move with a cutoff criteria: cut after 2 succeeding good moves. The result in the following position was that Arena quit the search early after a bestmove change from one avoid move to the other.

regards,
Edmund
