Question 1: Is anyone really folding to a minimum raise here? On my tightest of tight days vs a loose passive table, then I'd fold. Most of the time I'd call though.

Hero bets $6.50

Question 2: What is the best play here if you think that you will get called about 40% of the time, they will fold 40% of the time, and raised 20%?

Question 3: If you are drawing to both nut flush and nut straights, does that change your answer to Q2?

Question 4: Returning to the original hand - say that you are called in one spot on the flop. The turn card is either a non-diamond Queen or a low diamond, do you check or bet?
