The Laws of Chess

[Andrew McHarg]

I think going to the toilet five times within the first eight moves is certainly unusual, but isn't close to being conclusive of cheating. Logically speaking the opening is not the time that you're likely to get the most advantage by using an engine anyway, as many of the moves are theory. For someone to get the most out of cheating they'd be better spreading their cheating sessions throughout the game and getting some ideas in the more complex middle/end game positions. However, why anyone would want to is a different matter entirely. :\
