How to play 2 pair in O8B?

[GeoffM]

I'll normally bet out if I have top pair and another pair and see what happens. If I get a bunch of callers, I usually start checking and possibly considering a fold depending on the board. Two pair is relatively weak and unless you can get your house it won't win pots 9/1-0 times, losing to a straight, flush, or set.

you hav eto play two pair very cautiously, in general. the only times that i am particularly agressive with 2 pair is when i have top two, and there are no straight or flush possibilities out there.

in addition, you have to think about the low half of the pot. if you have the low locked up, then your two pair is dfinitely worth betting. but if you are betting your two pair whehn there is a low possible, and you dont have the low, you are just throwing away money.

I would think that at the 3/6 level, you do not have that many callers preflop. Basically, you are assuming a level of competency from your opponents.
With that said, You can be aggressive but faced with a re-raise you have a decision to make.
Perhaps this time you can lay it down, maybe next time don't.
With a safe board (Read, no flush, no straight, your only worry at the moment is a set.)
Keep in mind that your opponent knows this too. Does he even have a set?
Does he even have 2 pair? Maybe he is just drawing, and maybe still he is just making a play.

Although it is wise to fold when you think you are beaten, sometimes a re-raise is called for too.
