I can say this about poker.com BJ I have been useing it and as far as the number of decks they simulate they might not want that public... but over all I have notcied that its is very streaky I have gone on a run of 10 to 20 winining hands then all of a sudden the comp withh hit bj after bj on me then it will just go to beating me by one each time... so just watch for the streaks
