50nl: Good spot for a bluff?

[The Bean Counter]

Pre- okay 144bb effective?

How about flop? My thinking was that nobody would c/r this flop texture with big overpairs, sets and draws and villain pretty much defines himself as air. I guess there's an argument for checking back with a gut shot and 2 overs, but I would normally bet my entire range when checked to here, as villain's c/f with a high frequency at this stake on wet textures. How about the sizing?

Should the fact villain timed down before c/raising flop sway us more towards the flop 3bet?

Villain is 0/0 after 4 hands and assumed not terrible.
