lol. I would be surprised but having played a while at these stakes..... I'm not. It's astonishing what people will call you down with. Yes occasionally they love to slowplay trips as they think this is the height of smart poker (value? What's that then?) but you get called with junk like this far more often.

Sounds like you're using sensible BR management, just resist the temptation to get bored with terrible players and move up before your BR is ready.
