In this case, if you re-raise all in, i would say that you are probably only going to be called by JJ+ and AK. In which case you are in deep shit 2/3 of the time and racing for the other 1/3.
If you re-raise and villian folds your stack has gone up from 25 to just over 30bb, which is nice, but not brilliant considering that you are risking your entire tournament in this spot.
I really think that, in this particular situation, it would be better to CALL, with the intention of set-mining, and folding if we fail to hit our set.
I originally felt that folding was the best option, and i still think that this is correct if we aren't gettiong the necessary odds to set-mine. (See questions below)
Two things you're missing completely are 1) the times when he folds which negates our EV damage when he has a dominating hands, and 2) the times when we go set-mining, miss and fold a better hand, or when we have to fold on flops to hands we would be in good shape vs pre flop we're loosing EV there
the reason TT is a strong hand is because it has such good equity vs lots of other hands, by set mining off a small stack ur burning so much of that equity, basically turning it into 22/33 which i dont think anyone would argue is a fold in this spot
