But since the int16 goes from -2^15 to 2^15-1, and in the EPD standard, the interval of possible values goes from -2^15+1 to 2^15-2, you can use the values outside of this interval for +/- infinity inside the search. > >> >>I will check the EPD standard again but I do not think they contemplate the >>possibility of using -32768.

You got me wrong or mixed C and EPD standard. >>>I think i will use a new opcode "om x" (= opponent mates in x) and then add a >>>"ce" opcode to make it clear for other programs.
