Pre-flop call questionable obv, but the major question here is do you think it would be +EV in terms of outs and fold equity to CRAI on the turn instead of leading again?

The reason you don't make the preflop call is because you're going to be OOP the whole way, and when you catch a draw you're going to lose money a lot of times, just like this time. Your cards are plenty good enough to make this preflop call in position, though.

Is there a some kind of graph that someone can create that will show us how much Fold equity people have against particular one pair hands at different buyin levels? Because I don't think Fold Equity enters into the conversation at NL25 much at all. I think if you CRAI the turn, you are getting called here, mainly because of the way the opponent acted throughout this hand(CS tendencies, maybe had a big hand the whole way and pretty much only bets when it's checked to them).

Guess I'm just curious as to the gap at NL25, 50, 100, 200, and 400 between opponents when it comes to fold equity.

depends so much on the opponent.

sometimes you have FE at $25NL. sometimes you have none at $400NL.
