would be interested in views on a couple of hands. First one is second hand of a MTT - starting chips were 1500 and blinds of 25/25. I won the first pot, a few hundred chips, but other than that pretty even all round.
I get dealt

in mid position. Folds to me and I raise to 100. Two callers behind and the SB calls 'for value'.
flop comes down

. SB leads out for 200 - what would you do here?
the second hand I think I know exactly what I should have done, but would be good to hear other opinions or get my thinking confirmed. Same comp - still 25/25
I'm dealt

UTG +1 and limp in. Button calls, the SB and BB check. Flop:

checked to me, I bet 100, button calls, SB and BB fold. turn is

- what now?
