Around 11 pm on a Saturday night, this is a horse track that has high traffic and lots of drunks from the Kentucky Derby earlier in the day...

Hero - young 20s white guy. Only played 2 hands since villain sat, one was JJ where I 3bet shoved on 2 short stacks. Another hand i raised A straddle and 2 limpers to $22, villain limp called. I Cbet a Q85ddd flop, villain flats, checked a 6 turn and river a Kd, villain bets and shows the flopped nut flush.... Hero has around $320 and has mainly been doing a ton of folding since villain arrived.

Villain - young early 20s Asian male. Extremely wide opening range, with a ton of bluffs on multiple streets. Raising its 68s, A4o, 67o as well as pocket pairs 55+ and suited aces. Hero just shoved A8 suited and won a 3way all in last hand, villain has $190.

Preflop. BTN straddles, 2 limpers to villain who makes it $25, Hero looks down at K9ss and 3bets (purely as a bluff) to $80. Folds to villain who tanks for an abnormally long time, and then calls.

Flop: ($175) a73 rainbow, the 7 was a spade. Villain thinks, Then leads for $5. (Yes $5). Hero....?

Edit: --- villain has been 3bet a few times at the table. He's not 4bet shoved once, twice he folded, once he called and folded to a Cbet.

Note: I have not seen villain make a freakishly small bet like this previously. I've also never seen villain in this card room before. Another player commented that he didn't know villain played cards (they play basketball together) but villain didn't seem to respond.

just treat it like a check.

on such a dry flop like this i'd bet somewhat smaller, just as i would if i actually had tp. 100-110 seems fine, and giving up if called.

I would like to know how this opponent responds to 3b before 3b bluffing

I edited my post, thanks.

Keep in mind he started the hand with around $180, so it's pretty much a shove otf?

sorry, thought we were 320 eff.

in that case i shove. but i don't like the 3b nearly as much now if you don't know how he responds to 3b.

you pretty much have to shove on every flop. would probably make the 3b a big larger then to set up a pot sized shove
