But why would he just presume you are trapping? Theres always the chance he miracle flopped the straight and once you gave him action he checked the turn to get value on the river. Which would have worked. I said already it was a nice call. Better to follow your read and be wrong then not follow it and be wrong. Its near impossible sb vs bb to put someone on a hand tho when its limp/check preflop. A cardinal rule of poker is to not go broke in a unraised pot for that reason. But what i really meant in my first post was that on a board like that in an unraised pot, follow your read and call if you think your good. But i dont think that in that spot even with your read its a snap call.

I meant by the bluff thing that he could have A9 or even 2's-4's. As well as any combo of rags to give him 1 pair.
