Q3 desperately needs reads, is this a TAG type, has he been stealing earlier, does he raise flush draws, what level is this 2/4 or higher where stealing is more common?

VS the correct type I would be inclined to call and donk-bet a blank turn. I voted fold on flop on this though without reads.

If he is a TAG he is probably raising AK KQ, KJ, AQ, and so on.
If a weak passive type is raising from the button I am also inclined to evaluate my hand strength as he seldom raises, this tho is a weaker tell than the TAG. A reraise on the flop from a weak passive type is a strong tell that you have been beaten.

At last is the tricky type that I would call down against just to avoid steals. I do think we are behind most here though.
