1) Ok, so of my PF range of 22+, AT+, KJ+, A7s+, KTs+, QTs+, JTs, T9s, 98s, 87s,
I'm betting the flop with 55, 66, TT-AA, 78, 89, any 2 missed overcards.

That's a total of 37 combos that I'll be continuing with against a raise 55 (3), 66(3), TT(3), JJ-AA (4*6=24), 78s (4). Then there's 16 combos of each of AK, AQ, AJ, KQ, KJ, QJ and also 4 combos of 89s that I'll be folding, for a total of 100 combos folding. Umm, okay, I don't want to get raised here. You said the button was tight, right?

2) I'm betting the turn with 55, 66, TT, JJ, KK, AA, KQ, 78s, 89s, and AK, AQ of spades which means that I'm checking the rest of my flop betting range. So that's QQ (6), along with AJ (12), KJ (12) and QJ (12) for 42 combos I'll continue with against a raise, and AK, AQ except the spade ones for 30 combos I'll fold. Looks ok!

3) Flop c-betting range is exploiting the fact that he calls pre-flop with a tight range most of which is missed overcards with no straight or flush draw on this flop, and we expect him to fold these hands to our bet.
