hand1: that's a big field we're betting into with bottom pair (no kicker) OOP. check/fold the flop. now that we've picked up a draw, we can check/call the turn. As you played it, when it's 2 back to you, you're getting 5:1 to call for your flush draw, assuming it's good. river is A-OK.

hand2: not sure what to say without reads...the play is hugely dependent on the reads.
