You don't have enough information. Looks standard, now fold. If after more hands you don't suspect CO is position aware, i.e. low attempt to steal, calling can't be that bad. Readlesss I'm not sure need to look at my data mining more which I just recently started, there are an awful lot of tight players that open basically same hands from every position. Not sure which is more standard, a blind stealer or just an unaware tagfish.
