simple preflop decision against shortstacker

[DJ Sensei]

UTG (35/22, the table mark, 70bb stack) opens to 3.5bb.
CO (22/21 winning shortstacker) shoves for 25bb.
SB (me, covers both, winning TAG image) has 99

(BB is a TAG who covers me, but thats making it more complicated than it needs to be, so lets not worry too much about him unless people think he really matters)

call or fold or minreraise or shove?

How about TT, JJ, AQ, or the other marginal hands? If you think answering more than the original question is giving up too much information, thats ok (I disagree). The important thing is we all learn how to beat up the shortstacks, so the more you have to say about situations like this, the better.
