Raising for info is obviously ******ed unless villain plays %100 face up vs raises and donks/calls his bluffcatchers on flop a lot.

But seriously, nobody is gonna donk any2, then 3bet with the same any2 because you are prolly raise/folding for info.

eww at raise/fold. this spot is basically always clearly flat or raise/call. if you can't say, you play a smaller pot IP and call

If he did, it would have to be: A Q Given that UTG raised coming in, that usually means big cards: aces, kings, or queens wired, or AK. The only thing he can reasonably beat at this point is AK, if holding TPTK. If he had top pair, top kicker, nut flush draw, it's more likely he'd want to keep players in at this point so that he can get paid off if the spade hits, and save money in case it doesn't and his top pair is no good.

That he doesn't fear the initial raise makes it more likely that he has something like aces wired, and played 'em slow from the BB, or that he has at least 76, and flopped the bottom two pair, or has better than that.

Pretty sure an UTG raise doesn't usually mean AA KK QQ or AK.
