It really makes no sense to frame the question like this. Each situation has an optimal range for going all-in, and it can be as wide as jamming or calling with any two cards, or as narrow as folding even AA. The latter would be near the bubble of a satellite or DoN format, when you have enough chips to fold your way to a cash.
So rather than asking about a specific hand like TT, you should focus on learning, what your entire range should be in different situations. And its very important to remember, that just because you lost a hand, does not mean, the play was wrong. Poker is a game of
odds, and making the optimal play does not mean, you always win the hand. The CC 30-day course have some sections, where you can see examples of optimal push-fold ranges.
