Two Live Overpair vs. Flop Shove Scenarios

[Todd Terry]

I've cast myself as Hero in one of these, Villian in the other. Hero and Villain both somewhat active in both situations, no other relevant reads.

Hand 1 - Foxwoods $3K MegaStack

Hero and Villian both have 19K, 100/200/25. MP who limps into every pot limps, Villain raises to 800, Hero raises to 2500 on button with QQ, MP folds, Villain calls. Flop 6 5 4 rainbow, Villian checks, Hero bets 4K, Villain shoves. Hero?

Hand 2 - Borgata $1500

Hero and Villain both have 9K, 50/100. Villain raises UTG to 250, gets 4 callers, Hero raises to 1100 with KK in SB. Villain calls, rest fold. Flop: 7h 5h 3c. Hero bets 2500, Villain shoves. Hero?
