what moments could we use? how they react to specific attacks?
i don't think your use is the same as mine. its not really meant to be a predictor of what they will do. Its a descriptor of what they are doing. then we can point them towards players who already doing what they do but better.
If we review the last ten replays of someone. we can get a pretty go idea of how they play.
for example you said you are a risk taker. So you would be on the higher end of being a risky player. if we had a line from risky to conservative.
risky<--I------->conservative
and if we can do that why not for other things.
freeflow<---------->forced

so i would propose getting replay dumps of the last ten replays of people figure out what adjectives are applicable. this will rely on an honesty system. got ten replays for me? i'll post as i work things out and see where im going right or wrong.
then once i have enough adjectives i'll see what i can do with it.
i vote its still on topic because if we get this working it would make it easier to match students and teachers. and we could put the method in the tips. or should we make a new thread?
