$30+$3, KK, Lvl 1, Is folding gross?

[jaydreb]

This is the second or third hand of the tourney. No read on Villain. Raising the flop seemed standard, but when I get 3-bet it's either push or fold. Is a fold terrible? Should I be flat-calling the donk bet, or raising less if I intend to fold to a 3-bet?

vs an unknown I'd say its totally standard to get it in here

[Pudge714]

Snap call he has A9 or something.

[KCW12]

I'm calling this every time. 88 or 99 is a possibility, but you can't be afraid of it here. Expect to see stuff like Ah8h, TT, A9, JT, QhJh.

[DannyOcean_]

A9, K9, Q9, J9, T9, A8, A8hh, JTo or JTs, QQ, JJ, TT, 76o or 76s, Maybe even random crap like 77 or A3 or that. All part of his range here.

What we are worried about is 33, 88, 99, 89. He's doing this with a lot more hands we beat than hands that beat us.

I am not folding a good overpair to an unknown after he donk bets into me and then shoves.
