My thoughts on this are as follows:
-It's tough to weigh c/c because I don't know how cbet-happy he is. I could c/c the flop and lead/shove most any turn assuming that he'll bet flop/raise turn with a lot of draws, pair+draws and maybe even some air seeing as how my line is non-standard in a spot where we both have really wide ranges. This is actually my first time considering this option, and I don't mind it. I can probably barrel the river on a lot of board run-outs if he flats because he'll flat with a lot of mediocre pairs that have good outs.
-I hate c/c flop, c/x turn because if I c/r the turn, then I have to fold to a shove (which seems like I'm getting exploited), and if he checks back the turn, then I only have one street to get value/run a bluff that he'll probably call with preeeeeetty much everything that beats me.
-c/r: This play seems really bad because once he 3b's, he has nothing that will fold to a shove and i have ~45% against his 3b'ing range, so shoving over him is bad. c/r/c'ing is obviously dumb, so that leaves c/r/f'ing which just sounds like a great way for him to win a medium pot 100% of the time he has sets+ (as opposed to losing a big pot about half the time if I play it a different way).
NOTE: I lead for value a ton here (and people in general lead for value a ton), so my range is plenty balanced to do the following plays.
-lead/3b: I'm not sure about this, but this seems dumb. I can't imagine he's 4b shoving a range I'm any good against, and I'd be priced into a call, and I could lead/overshove, but we're talking about shoving like $9 into a pot of $3, and then I'm mostly facing the goods when he calls. I'm actually certain that this will make me a profit, but it doesn't seem optimal to me and I'm not sure what it does to my whole range.
-lead/call: This was what I was leaning toward til I thought through the c/c, lead turn option. If he raises, then I think I can c/shove the turn feeling pretty confident that he'll bet most of the time and feel like i'm getting plenty of fold equity (plenty more than my other, previously mentioned shove options) from pair+draw, good draw and a little bit of air type hands. I can also lead the turn again if I spike my spade without my hand being face-up.
If he just flats my flop lead, then I'd barrel almost all turns, but a turn raise would put me in a pickle (but I don't think he's often going to flat the flop only to raise the turn). In that spot, calling, 3b/f'ing and 3b/felting all seem bad to me.
I think I like c/c, lead turn the most, but I fear I might only think this because it gets me in the least amount of spots where I don't know what to do, instead of thinking it because it's optimal.
