Hand 3 is tricky but I agree that a fold is in order. Do you feel like it's +EV to avoid marginal situations like this one, even if there's a chance you're ahead? I feel that putting opponents on ranges/narrowing them down is wonderfully useful, but when we're flipping against a range that makes sense to us, doesn't it make sense that our estimated range is slightly incorrect, possibly shifting the EV of a call into the red?
In hand 3 I meant QsJs. It was just a typo, and I've corrected it.

I'm not really sure what you mean about avoiding marginal situations in respect to hand 3. I don't feel like this is a very marginal situation at all. The only chance I have of being ahead is if I'm against KJ or if I'm against something like 7s5s, neither of which is particularly likely because of the flop re-raise and villain's tendency to be passive.

In regard to spots that you evaluate as being approximately 0EV, it depends on a few things like the rake structure and your image. If the rake is already capped, and/or if you think showing down in a particular spot will adjust your image in some profitable way, then your EV evaluation will change based on those things to where you think the spot is either marginally profitable or marginally unprofitable.

I think what you're talking about is something more along the lines of expecting to make mistakes, and folding in marginal situations since you think you might have missed something that would make a certain spot -EV. I don't think this is a terrible thing to do if for some reason you're so prone to tilt to the point that if you lose your later play will become relatively -EV. I also don't think this is a terrible idea for poker in general if you're new to the game you're playing, have recently moved up in stakes and are trying to get your bearings, or if you're multitabling to a point that it makes you more prone to mistakes.

However, at some point you'll have to mature into the shoes of a player who is skilled and confident in their ability to play marginal spots well.
