What can you do to loosen up a very tight table?
Played a 1/2 10 handed on UB last night.
Probably the tightest 1/2 I have ever seen. No more than 3 people saw any flop!
And thats only if both blinds called.
Was trying to think of a way to get the table to loosen up a bit, but just couldnt think of any thing that I was comfortable with.
I could have played maniac for a bit.
I could have announced "I am seeing the next ten flops, I dont care what it costs"

What I should have done, and usually do, is to find a better table!

But what if youre stuck there for some reason and cant find a better game?
Try to loosen it? or go to the movies?

You could attempt to play almost anything from late position...and just raise preflop and bet out on the flop. If it is as tight as you say, then you should take in some small pots. Keep doing it until someone calls you down or catches you...

It might make your image better and pay off your good hands...problem is at a 1/2 table, people usually don't notice your image that much. You have to leave the table or take a break...sometimes a ten minute break from the table is what you need to let new players come in and older players move on...
