hand 1 - hero raises at some point, ideally on the flop or at least the turn. If he is on a draw, you don't really find out by calling PLUS you let him dictate his own price for his cards.

hand 2 - I think you can raise a little more on the flop. Pot has $2.15 when it comes to you and you only pop it $1.50 more. First caller is getting better than 2:1 to call there.
