A draw must be claimed, there is no automatic draw. If a program is "stupid" enough to make inferior moves in an attempt to win after the 50 moves each, that is it's problem. Humans are allowed to play after the 50 moves each, so why should it be different for programs (and of course, the operator can always stop the game after the 50 moves). However, the 50 move draw can be claimed with 99 moves made. If it is the claiming side to move and the opposing side has made the required 50 moves, however, the claiming side has not yet made it's 50th move, that side can still claim the draw. This rule went into effect in 1997. TAKE NOTE PROGRAMMERS: It is important for programs to be aware of this since it is real easy to code in that 100 moves must be made. KarinsDad :)
