everytime over the last 2 days when ever i get in a good lead the oposing player seems to leave the game frozen and all i can do is concede ???? any help?

they may have disconnected sometimes this can take a few minutes,

id say be as patient as possible.

because they will get signed out give or take a few mins and that will give you the victory.

however if your in a tournament and your opponent leaves you win automatically and break ends.

this happens to me to or no1 gets the points and it goes down as no game was played, really annoys me

Yeah ive had that
