Note: I normally don't raise with A8os, its a very unusual play from me. Also I made a very weak raise once I hit my trip, much less than I normally would raise - it was a pretty weak play but thats beside the point.
I was definitely going to call with the one guy who went all in, I have a better kicker for sure, obviously (unless he made a full house, if so I cant do much about that). But when the second guy went all in I had to pause a second and consider. There are only 4 8's, and 2 are on the board...we can't possibly all have trip 8s, so I'm thinking there are only 3 options
1). The guy who re-raised all in is retarded. Unlikely.
2). The first guy was bluffing and the second re-raiser actually had the last 8. Unlikely.
3). The first guy has trip 8s, but the second re-raiser was slow playing trips on a rainbow flop and now has a full house. Likely.
In the end I didn't have the ability to fold my trip 8s and this is what happened. Would you fold?
