AK, funny action.

[MattiasL]

Do you have a read on BB? I have a hard time seeing what kind of hand he has. If he has a set or straight I would expect him going for the c/r the vast majority of the time. If I had to guess I think this is the flush draw or some strange two pair.

I might just call, but CO/UTG+1 would then get about even odds to draw to a three-outer, which is annoying. If anyone of them has more than three outs (eg pair + gutshot), we really want them out.

If we can fold to a threebet from BB, a turn raise seems like a good alternative even if the river action can then become difficult (do we call a river bet?). But we do not want to fold the turn against just two pair or a funny semi bluff in this big pot, so it is dangerous against an unknown.

I am not really liking either alternative here, but I think without reads I would probably just call. If CO/UTG+1 has a single ace or PP (most probable) this does not cost us much/any equity against them even if they call. And getting to see BBs hand for information has some value.
