Overplayed top pair?

[Eraserhead]

The call-down is fine, maybe calling down after the c/r is a possibility since he could be bluffing on this ragged board and you don't want to fold that. Since I don't think he's capping a worse J you only lose 1 sb when that's the case and you neglect to 3-bet.

FWIW, I never trust people buying in for the lowest amount permited. How does other people view this?

Last thing, he bought in for 10$ - 5 BBs right?
