yup you can select the option of "running multiple times" on pokerstars
and there are a decent number of players using it. If two players have this option selected then if they are all in the flop then the turn and river cards will be run twice, similarly on the turn and pre flop (whole board will be run twice).
It is good fun and you can use it to your advantage sometimes. All you have to do is mark the player on your table who has this option enabled (for this you have to put your chips in first time to find out). Once you know the board runs twice against certain player then you can start playing aggressive against him more often. Especially draws like open ender straight draws and flush draws to try and make them lay down the best hand. Thus you can win a lot of pots until the player figures out what you are doing.
