If the river is a heart they may either:
1) Have a flush to beat you
2) Give you minimal action

If the river is a diamond they may beat you with a flush.

If the river is some ridiculous shiznats you might lose to random-2pair.



EDIT -> I cant read at all. I somehow thought hero was button on the turn.


Anyways, The tag might be setting up a a raise anyways, so why not bet/3bet instead of c/r the turn
