Yeah, this response could be a book. Honestly for the Axs question.

You're not going to hit the flop enough to justify limping every single time you have it. The only time I complete or limp is in the SB and check the BB because it is cheaper and there's only one person to act after you. Too often, people will limp it, get raises afterwords and then fold meaning if you play that only maybe 20% of the time you'll get to see a cheap flop. So you'll have to make a lot each time you flop the nuts to make up for the rest of the time.

If you're going to play the hand raise it. No ifs ands or buts. If it doesn't merit a raise, then fold it. (with some exceptions)
