TPTK into passive opponent. & flush scare

[!Luck]

This guy never raises. Ever. Bets 25 cents when hit middle pairs. Not enough hands to really know but just say passive.

Was my value bet good on the river? Since i know i am not going to get raised?


Hand #2 No reads... but he called my reraise really quick so i was sure he was on a draw and the very quick check on the turn kinda re enforced that he hit. So river rolls around and i do not know what to do

Hand one is fine. You'll see Ax enough here.

Hand 2: If you really think he hit then your situation hasn't changed here, you gotta fold.

Hand 1: Seems ok, I like the river blocking bet.

Hand 2: I'm calling this a lot, but its super player dependant. Could go either way.
