Great hand to post, as this is one of the most common spots and it’s worth creating a default profitable strategy for this spot. You can then deviate from that depending on villain and stack depths.
Key concepts for you to research are fold equity (when considering a raise or jam) and your equity when called. The latter can be derived from a free tool like Equilab. There will be some strategy articles on this site to help you understand these concepts, or you can Google fold equity examples.
FWIW button vs cut off with TT, I will 3bet this hand for value against the cut offs calling range, plus I’m also happy folding out hands like QJo and denying villain his equity. Against his re-reraising range it’s a close spot and decision between call or jam depends on villain and stack depths. Against an aggro Russian or Scandinavian regular with enough bluffs, i’ll rip it in and expect to get enough folds and calls versus hands I’m flipping with. Against recs, I’ll flat if we’re 125bb+ effective (I.e. we both have at least 125bb) and set mine. Any shorter and I’ll let it go. Hands like JJ/QQ in that spot against recs are the borderline hands for me.
