Hand 1: You need to consider checking behind here. Table is playing loose and you have a draw to the nuts with a backdoor flush draw. Betting has a little fold equity and might get you a free river card, but it might get you pushed off your hand.

Once you're c/red you need to do some math and figure how often he's following up for all of the money.

Hand 2: *shrug*, I usually just fight these guys on the flop as he seems too loose to fold anything pre-flop. Second time around, it's probably a fold and once you see a flop I don't see any other way to play it.
