no move game cancel
User1 puts hand up for a new game, then goes to sleep. Later, User2 clicks play and waits for User1 (Black) to move. (And waits... And sends message to User1 "Wake up I want to play" And waits ... ) After a few minutes User2 tires of waiting, closes the game window and loses by forfeit. Not fair.
Some possible solutions -
1 - If a player is 'sleeping' the game request is removed.
2 - an option to cancel a game if it is no first move after one minute
3 - Forfeit if no first move within one minute
If opponent does
This is already mentioned in another feature request. Note that games below 20 moves dont affect rating and dont go to history. So you can resign or lose by forfeit and nothing will happen.
