3 uber boring MTT hands

[mdwexford]

Hand 1 - Level 1, blinds 25-50

i make it 175 to go in EP with 10-10, one caller in MP

flop is Q-4-Q

i lead for 300, he makes it 1100

my play??


Hand 2 - Level 3, blinds 75-150. Villain is playing 6.5k-ish. he makes it 500 from the cutoff, i flat call with As-Kd in the BB (playing 18k)

flop
2s-6s-8s

i check, he bets 600, i call

turn Jh, i check, he bets 1400

my play??


Hand 3 - Day 2, blinds 800-1600. i have only been moved to this table about 2 orbits ago and have doubled up since i got there. average stack is 45k, 33 players left.
i open with 10-10 to 4400 from EP (playing 25k), Villain re-pops to 12k (playing 35k). i figure his range here could be 7-7+, A-K, A-Q.
if i push here im getting called by an overpair or A-K, A-Q and i dont want to race so i decide on a stop and go. so if he has overcards and misses the flop he will fold to my bet and even if he has J-J or Q-Q he could fold on an A-K-rag flop as me cold calling his raise oop looks strong. this is obviously bad if it lets him get away from a smaller pair that he would have called a shove with preflop. so i call the 12k and shove my remaining 13k on the flop. opinions please??
