NL 100: 3-barrel bluff

[Robert]

Opp is pretty tight, a bit on the weak side (he has seemed to be folding to raises postflop in a lot of hands). When he called my flop bet I put him on an overpair. My image was semiloose-aggressive. Is this 3-barrelbluff too much? should I just slow down after he called my flopbet? Or is this a good oppurtinity to blast a nit out of a big pot?

RR preflop. This should be automatic if you think your opponent is weak/tight. I would give up on the turn though. It looks like he really wants to show his hand down. Shove river if you want to bluff at it.

he could easily have a monster but that makes me skeptical why he wouldn't reraise the river. i could see him having an overpair as well. i don't mind the flop bet though, and the turn is a common move in my arsenal as well, but i think you need to lock it up by the river.

only a better hand then yours is going to call that river bet. and if would call $50, i think he would call $63, so a push wouldn't work in this situation. i think you need to just cut your losses and check it up here for the cheaper showdown.

reraise preflop would have told if the line you took would have worked.
he called you dead through two streets so hes gona call a river
