I'm new to this site, read the FAQ, but I apologize in advance if anything is out of place here. I've started to play a bit more tournament poker and wanted to start walking through some hands to make sure I'm generally in the right mindset.

This hand takes place in a local $50 buy in donkament at a charity poker room. We're about 90 minutes into the tourney (late reg hasn't even closed so bubble is still far away); current table appears to be two/three OMCs, one maybe LAG, and some solid MAWGs that haven't really gotten out of line so far. We've played a few hands and not yet gone to showdown, so not much of an image.

We're sitting with 50BB at UTG+2 and wake up with TT. No antes in play yet. UTG (the slightly LAG) and UTG+1 both limp and we pop it to 5BB. Folds to SB (who covers us) who three bets to 15BB. It then folds back around to Hero and we're heads up with a 23BB pot. My thoughts (from worst play to best play)...

Fold: Can't imagine we're ever folding here unless we have a significant history with V and we have them dead on for AA/KK.

Shove: At this point, I'm debating between a shove and a flat. The only hand I think we're folding out here that beats us is JJ. We block TT and QQ-AA is probably calling. We're also in position. This leads me to my eventual decision...

Call: We have position and I decide to flat. We can evaluate flop and potentially get value from hands that V would fold to a shove but continue OOP that we beat like AJ-AK if the flop is clean.

Thoughts?

After we call, the flop comes TJQr. V leads out 20BB.

I don't think this is that controversial of a spot but wanted to check. Again, from worst to best...

Call: Flatting is pretty much out of the picture with our stack at 35BB. That would leave us with 15BB and 70+BB pot. There's pretty much no turns we'd fold to for that price and we're giving V a free card. Thus, it's either shove or fold.

Fold: Folding just seems super nitty here. It feels like V would take this line with almost his entire range, and we're favorites against AA/KK/KQ. But, we're crushed against JJ/QQ and in bad shape against AK. Despite that, we decide to...

Shove: We don't have a whole lot of fold equity here, and if we do, we're crushing it anyways. But we do crush a lot of V's range and we don't want to give a free card. This would be a shove for value.

The shove eliminates the need for a river decisions, so I'll end it here. Am I generally making sense?

Thanks

I played a lot of live donkaments and most of the time live players in 1 50$ tourney do not get out of line that often.
I would tend to fold TT pre there in that spot. Yes you are in Position but even if the flop comes 9 high and you face a slightly large bet you still have a tough decision imo.
This 15BB 3bet from BB looks strong and in a 50% live tourney it often is what it looks like. QQ-AA... the best you can hope for is AK.
As played shove Flop for sure.
