The correct 6-max poker strategy is to play looser than you would in a full ring game (open 20% of hands) and make more bluffs and wider call downs. This means that in a 6-max game you should be playing a lot more speculative hands like suited connectors and suited aces as well.
But here is the quick answer. PokerStars is not rigged. It just appears that way sometimes due to the incredible speed of online poker. Because online poker sites like PokerStars typically deal hands 3 times faster than a live poker game, you should expect 3 times as many bad beats.
