Hand 1 is kind of a hard spot. What is his range on the flop? Has he donked before? Does he play his draws aggressively or passively? What does he 3b small like that?

OK, if he's a decent player, he won't be 3b that flop that small with just a queen. He would have to have a high club + pair or a made flush. If he had say QT, why would he let you draw to a club by giving you such odds that you wouldn't most definitely peel with a club? He either holds the ace or the king in his hand and wants you to make your flush and lose money or he has a high flush already.

However, whether he is good or not, his small 3b is NEVER a bluff. You have to assume Qx or better.

Hand 2 is standard.
