I don't know how to play this. AQs 3-bet from MP.

[brick]

EP raises and I assign him a wide range of big suited cards and pairs. 99+ KT+

I 3-bet AdQd.

SB is kinda crazy. He caps. He would probably cap a pair bigger than 44.
I'm not sure if he would cap with a random hand. Maybe 10% of the time he would cap with a random hand.

Flop: 8s 6s 3c

SB bets, EP calls.

My action? (if I call SB will bet again. Not sure what EP would do with a hand like KJ. I think he will call with an A.)

What do you guys think about cold calling pre-flop?
