Whats not easy for us to figure out, is how much each player had in chips. What if CO's stack was that which should've just pushed rather than min raise? That might give more information than just that they covered you. Without any reads all I can think of is shove, because it depends on what you thought their ranges were in that spot. If they had AA or KK, then either poor timing, or you made a poor read. Otherwise, QQ looks mighty sweet, and you obv thought so too. Absent any other info, I'd do the same. =)
