When you play a 6max table you do loosen up, but only in high card strength. For example, if 2 fold and you are CO, you want to raise K9o or any A. True, suitedness helps, but what you really need is high card strength. A good formula for the average 6max table is make a raise or fold decision on your starting hand based on high card strength, and then bet relentlessly unless you know you are beat or have the worst of it. Remember that anyone who has 2 unpaired cards has only about a 30% chance of hitting a flop ... your A high is pretty good even 3 handed.
