I'm an experienced live deep stacked cash game player trying out tournaments, not sure how to navigate postflop spots 30-40 big blinds deep in mid-late stages of mid-sized, soft field live tournaments. (e.g. general tips on cutoffs for hand strengths where I can start aggressively playing for stacks vs. pot control)

For example, when 40 big blinds effective (which is avg stack), 28 players left and 13 spots pay, is top pair + flush draw strong enough to play aggressively for stacks in a single raised pot, big blind vs. button open, or is that a future game/variance punt in a soft field?

(obviously this is an ambiguous/situation dependent question, not looking for a specific hand history feedback, more so general concepts on how to approach growing vs. controlling pot sizes with various hand strengths at 40 bigs)

I think at 40bbs you wanna focus on playing hands with 2 high cards generally that can make top pair vs speculative hands such as 56 or 67 suited etc. You should be folding low pairs from EP liberally. for example, raising KJo is a much better move from say ep 40bb deep vs say 100+ bb deep I would say. Probably not a raise say utg or utg+1 at full table but just trying to get a point across here.

I would look at SPR for stack offs. I tend to think a flush draw + top pair would be good enough against most villians like you stated but its hard to analyze a spot like that without knowing much about the villian.

Something at 40bb deep, I wouldnt open to anything above a min raise if you are confident post flop. Even 2.1x seems stupid to me bc 2.0 is basically the same thing risking less chips. I find it kinda goofy when people will raise to say 3x or 2.5x+ with a hand such as 55 utg and then show it if its folds etc. Its funny how people get scared to play certain hands and will raise more to try and induce folds. I've even seen people do this with JJ which is just comical. Your raise size should be the same IMO for all hands unless there is a certain dynamic you can exploit; say you are sb vs bb, im fine raising over 3x to not give villian great price to play in position.
