2 hands against FLIPokeHer 10/20

[berserk]

FT 10/20, Villain in both hands is FLIPokeHer, TAG who I don't have any history with and don't know much about, 23/17.

I hate how I played both of these. The first one happened before the second, though on a different table. I certainly think the first one affects the second, so I'm showing the results for the first, but I would like comments on both.

1)

First - Turn pot bet really threw me off, he made it fast as well, and I felt like it was very often a Ahx type of hand. And river, well it sucks, but I'm a station so I called.

Second - I of course 3bet sometimes (mostly). I think I should have bet the turn as well given the board (bet/call or bet/fold?). Given that I checked, what do you do? And what do you do on blank rivers? 9/A rivers? Spade rivers? Original raiser was OtisRush (30/15 weird guy)

Assume that if you call, you check a blank river and villain bets $840. Also note that villain may think I'm a station based off the first hand (it happened about 10 minutes prior); also note bet sizing differences between the 2 rivers (and that he had the nuts in hand 1).
