yeah it's just the stop and go. If i was parachuted into the hand without reads and preflop action, yeah i'd call the flop raise and donk a safe turn - if i am raised on the turn i fold.

so:
1) yes i'd do what S says here
2) i would bet-fold the turn
3) i wouldn't do this, but if i did, i'd call the three bet and bet-fold the turn (since this is the same turn line as above, this method costs me an extra SB which i why i dont do it).
