One of my opponents account was closed, what happens.

they will timeout and you will win.

okay.  some member told me that it would be treated a resignation.  Is there a minimun move limit on rating adjustment?

Yeah, I think you need to get 3-5 moves in for the game to count, ratings-wise.

 But your rating could still change as a result of your win-loss record.  And your own RD changes too, so that can affect the next game, too.

You will destroy him now.

See post #7 here stating all resigned games count. Ignore the reference to themed tournaments. There was and continues to be confusion about this issue.

Note: The help file entry mentioned in that thread was changed to remove the reference to minimum moves.

Try to move twice since he's not looking...
