Hand 1 - Fold, your only beating Kx lower than KQ and would SB call a big raise OOP with anything like that? Doubtful, unless you have reads he's a loose fish. Much more likely a flush or set turned boat here. AA and QQ would likely re-raise preflop. JJ-99 is a possibility preflop but unlikely given postflop action . A read of some kind would be helpful but without one, im folding here.

Hand 2 - Id fold preflop. MP1 raises small even with 2 limpers, that can mean a monster he doesent want to scare everyone out with or maybe a PP/SC? Dont like the flop re-raise here, your building a big pot with top pair average kicker. When he calls im done with the hand. I would check the turn and fold to a bet. Fold the river... please, he's given you good odds to call the river bet, but ask yourself, what do you beat? a worse boat and A high? both of those are highly unlikely id say unless you have reads hes a total donk.
