I have participated in one of these $500 free play promotions, the winnings have been transfered as bonus chips to my account after I have made my first deposit. I followed the big bet strategy as described in aka23's

website and made a win

. Now a little part of my balance is the bonus money that was transfered from the "$500 fee play winning" , should I request a withdrawal now and forfeit the bonus money or is it better to wait until I playthrourgh the bonus ?
