How do I make gnuchess really really dumb?

[CThinker]

Option 1:

Remove search and eval. When asked for the move, simply generate all the legal moves and randomly pick from the list.

Option 2:

Reverse the root sort. I.e, pick the worst move.

[Vinvin]

Add a random value (from -2 to +2) to each root moves. Or from -5 to +5 to make it really really really dumb
