Anosmic,

Hand 1: Bet $19 on the river, and get a weak call wrong TP.

Hand 2: 4-bet flop, only hand you are afraid of here is AA and that hand isnt very likely. Build the pot on the flop, if he just calls your 4-bet, then push turn. Dont bet worried about the 3rd flush-card hitting the turn, you dont have to worry about flush draws in raised pots like these.
