Between flatting and raising I think I lean towards flatting because it allows the guy to continue with his donk bet bluffs, you lose less when he does have you beat, it's likely not going to be super easy for him to improve when you have him beat and you can obv still get 3 streets from him when he checks turn and has some sd value.
how does JEM have such a big stack? he must be v good???
prob some huge fish on a heater, usually that's the people who have huge stacks since they are always getting it all in a ton and either busting or sucking out
+1 to whatever Ricky said against unknown. Depending on who villain is, vs some tight bettors, I could find a laydown on a blank turn. If he's std fish, I probably just call down.
