Ok to chase on 6th?

I didn't think a straight was likely enough given that kings were dead to justify a fold against a more probable 2 pair with the pot as large as it was. Acceptable?

Yeah, with two 8s and two kings gone, I think you can call. You’re probably gonna lose to two pair more often than to a straight.
