2 weired spots on river

[recallme]

1. Villain is unknown, Nl2k 100BB effective

H raises to 70 with QJcc, 2 folds, V calls, 2 folds

Flop comes QhTh3c 170$
H bets 140, V calls

Turn is 7h 450
H bets 320, V calls

River is Qh 1090
Hero bets 600 and gets called by Kh5h

My thought process on river was, that i can`t c/f my trips now and he would check all weaker hands behind and bet all better +some bluffs.
Now reading what i wrote here, i could se a point for c/f, but still i like b/f better. What you think?


2. Same Villain, now with the knowledge he`s loose passive

Hero raises to 70 with T9hh, 2 fold, V calls, 2 folds

Flop comes QcJc5d 170$
H leads for 120, V calls

Turn is 8c 410$
H bets 330, V calls

River is Qh 1070

Board is now paired/ 3 to a flush and i have the nut str8.
I think there isn`t too much difference to the spot above.
Is this a b/f again?
