2 Super Monday Hands

[Ian J]

Hand 1: I have just doubled up to T4300 at the 100/200 level with about 250 people left in last night's Super. UTG (1900) opens for 600 and I'm UTG+2 w/ JJ. Action? My read is nil because he's just moved here and I'm multitabling.

Hand 2: I have 2300 still 100/200 and I'm UTG w/ TT. I make it 575 and a shortstack in MP calls, leaving himself 900. I'm planning to push any flop when the big stacked (9k) BB calls as well. The flop is A23 and the BB checks, I have 1750 and the pot has 1800, what now?
