Technical Mishaps and Engine Crashes:
************************************
If an engine crashes, stalls, or disconnects during a game, the game may be replayed or scored as a loss for the crashing engine.
In the case of a neutral event or technical glitch unrelated to the engines, the game will be resumed from the last known position.
Games must complete four full moves (8 plies) to be official. If an engine crashes before ply 9 there is no penalty and these games will be replayed.
Games must begin with the moves provided by the opening book. Games beginning with any other moves will be replayed.
All replays will be played at the end of a round, or at the discretion of the Tournament Director.
