Agree with most of your doubts, MDMA. Have one more:
pretty sure that the answer to question 26 should be fold in stead of push.
T3o in middle position, blinds 100/200, you have 1000, rest of the table has 5000.
Very much doubt this should be a push given realistic calling ranges from all the players behind you.
open push, it has been folded around to you so this is a perfect opportunity to take it down preflop.
