Hand 1 - Most of the time I see a big stack limp in LP around the bubble its because he wants to see a cheap flop and take the blind's money without committing chips preflop in a stealing position. Jack it up preflop. As played, push the flop. I think he has a draw here or overs, KQ, QJ, J10, Q10, all make sense.

Hand 2 - What makes you think your pot committed to a reraise? You already read CO+1 as a LAG, why not test him? I don't mind your line, but I go with my read and make it 1800 preflop. You will still have 4800 behind, definitely enough.
