<font color="gray">UTG folds</font>, <font color="red">CO raises to t200</font>, Button calls t200, Hero???

CO is unknown.
Button is a solid player, but after playing with him a bit, I can't pick a hand that he would have coldcalled here with. That was definitely out of character.
BB (shortstack) is weak/tight, and would only come over the top with QQ+.

Can I call here?

Call, you have decent set value here.
