How are points determined in a "left" game vs. a checkmate?

Is there some place where I can go to read about the points system.

I want to know if I am about to win a game and the opponent simply leaves the room instead of making one more move and letting me get a checkmate or resigning does it affect the points gained or lost to "claim victory" or wait for the time clock to run out?

How are the points determined?

Thanks all.

No change. Either way, you get full credit for a win.

Thanks.
