Have you already noticed that many times you are playing games and when your opponents have an important piece or position loss they just disappear from the game. What is this for ? Fear of loosing a game ? Attempt to get a win thru time-out ? Penalization because you are winning ?

Is there any possible way to incentive all players to prevent or stop doing this ? 

Just be cool, don't think about it-problem solved.

Well, I am not complaining, neither becoming un-cool, what sometimes happens is a behavior that anyone should not be proud of.

My quick thought is a ranking of fair players, this ranking could be based on a quantity of "fair trophies" conquered. I don't know if this is a good idea, just wondering....

setting a 24 hour limit could end this

move or loose

i think the idea is the other player will forget where he's at and make a mistake

i'm open -- come get me
