SB/BB play in 6-max

[ChuckyB]

I'm wondering if you have any guidelines for playing out of the SB/BB if there's a raise and/or 3-bet in front of you...and you don't perceive it to be a steal attempt?

.50/1.00 PP today, I was in the small blind with KTo. UTG raised and CO 3-bet. I thought about it...wished they were suited...and threw them across the room.

I haven't studied it much, but I figured if it's 3-bet to me in the small blind, I'd need a hand worthy of calling/capping a 3-bet. Even though I'm already in for half-a-bet, I'd think the terrible post-flop position negates that.

I find I end up folding to most single raises in the SB if I don't, at least, have a hand I would consider raising with (along SSHE guidelines). I'll call with moderate to big suited-connectors (as low as 98s if there were enough people and I felt frisky).

How do you handle it?
