Facing the Turn bet, All-in seems to be the only raise size I feel comfortable with my range. I can shove with my bluffs and value hands. With the SPR, raising smaller seems odd. My concern is having him fold all his weakest hands, and only calling when we're crushed. I do think there are likely hand's within his call range that we can beat (KT, pair+draw, spaz draw call, hero call). With this exact hand in my range, I feel as if there are very few river that I want to see. So my main function was for protection and to deny equity.

If our opponent always give's up with worse on river, there isn't too much value in flatting the Turn. If our opponent only jam's river's that improve him, also bad for us. If i had trips/two pair/AA, then I'd be more inclined to just flat the Turn.

Is my hand too marginal to jam, and too strong to not let my opponent bluff the river?
