I've been tring to implement the advice as given in the thread I opened previously:
http://www.runitonce.com/nlhe/slightly-positive-6max-nl2-player-wantin/

I've been opening wider and 3b-eting more. It seems to be more profitable, so thanks! Today's session was 26,9/21/7,5. Agression still only 1,84.

Villain is unknown.

I called a 3b here in SB because I assumed his range would be very wide. It still probably crushes my QTs so it's a speculative call.

OTF I 3b to get him off his air and smaller pockets than JJ, as I like to 3b draws. Not sure how well this works in 3b pots where ranges are much stronger. He also bet less than half pot which I took to imply weakness.

When he calls the flop, he has AJ minimum, overpairs, and possibly a spade draw (AKs seems the only realistic one, so my shove becomes worse). Sets would shove I assume.

OTT I shoved since I picked up equity and the K seemed like a nice scare card. He should not have a K here, except possibly AKspades, and QQ/AJ/spades without K should fold.

Thoughts?

Ps. OTT I have 30% equity against an overpair. How can I calculate the fold frequency required to make it a breakeven shove? Even against aces, I assume there should be some fold equity since he should be scared of me having JJJ or a speculative smaller set that got lucky (which I'm repping).
