DERG, I am grunching, you know?

somehow, I don't think the read in hand 1 applies to hand 2. His pre-flop raising is a bit spewy, but not maniacal. Regarding Hand 2, most villain's pre-flop 3-betting standards are generally decent (he's not a 35/30/4 for example). In this case, I think we're often behind from pre-flop to river. I think you're goal is to get it to showdown, but I'm not sure it's worth it with this hand. I would probably raise/call the flop and fold the turn UI.
