Preventing draws by repetition

Thanks to @benediamond this has a really easy fix; just set change_tau_turn to 999.

So there is the problem of every game drawing by repetition...

I don't know much about ML but I guess this is similar to the situation in generative adversarial networks where both sides are performing "well enough" that no training is happening, so maybe research there for a solution.

Possible causes

• Same model on both sides (duh)
• I flipped all the data so white and black data points are isomorphic
• Not enough exploration or noise?
• Not enough training data
• Bug in MCTS??

Possible solutions

• Train white and black separately with a color plane
• Augment training data with SL
• Adjudicate the drawn matches
• Keep training (fake it til you make it)
• Introduce some artificial noise, ex. idk??
