Is raising too thin ?

[blankoblanco]

against this donk i wouldn't.

however against a good, hand-reading, thinking player i think a river raise can be pretty sexy here. it's so hard for you to have a good hand here. the missed draws overwhelm the rare 33, 44, or random Q that got there (which your opponent can't expect you to raise anyway). so a good hand-reader may do a lot of "bluffcatching" here
