[Elaboration]

Hand #1:

Step 5, five players left, 4 get paid.

BB 300/150

UTG:~1100
UTG+1:~900
UTG+2:~1400
SB:~5500+
Hero BB:~1000 after posting

Big Stack is pushing almost every hand. However, I snapped him off a couple times with hands many would fold with so his range may have tightend up a little.

Hero is dealt 66

All fold to the sb who pushes...
Hero?

Hand 2:

Step 2, five left (1-2nd = step 2, 3rd=step 2 replay, 4th = step 1)

BB=150/75

Hero is in BB with t1000 after posting BB

All fold to button with t600 chips(he has done nothing overtly donkish, nor anything particularly inspiring.)
He pushes, sb folds, I have 33.

Hero?

I feel like my bubble judgement is better for pushing than it is for calling.

Thanks for the advice-
