Not loving their flop raise but for that sizing I call and hope they check the turn and we get a free river. not folding for that amount, if they raised to $1.50+ I would consider making a fold as I don't expect them to bluff often at that size on that flop.

Good call preflop and probably a good fold vs x/r. We have an overpair but most guys just don't bluff like this at these limits. Usually some kind of trap with AA/KK.

An easy call pre flop versus SB reraising BTN.

As played I like the flop bet once he checks, but as it's only really for protection I would make it less than half pot. Once he raises I'm folding. It either a better overpair or a whiffed AK AQ but we never expect him to be bluffing frequently enough to continue without reads.

Looks WP to me unless you have reads that he has moves. At NL5z I doubt it.

He could in theory be doing this with like 76s, QQ+ plus maybe 98s, AK or AQ with BDFD maybe for bluffs? I think though if you call there are too many cards you hate to get to showdown profitably, and you might already be drawing to 2 outs.
