Thank you for this explanation. But, after 'printing' my own move, how can I go on searching while at the same time keeping an eye on any new input from the opponent? Is there some function which I can call to see if there is input available without actually reading it, or at least, which returns immediately? As far as I know there is not such a standard library function in C(++). If this is the case, is there one in VC++? Leen
