This one depends entirely on how the whole table looks.

If it is a reasonable Stars off-peak lineup of half-decent players, I take my gamble that he has KJ QJ or some wild bluff here.
If it is a nice peak-time game loaded with nutters then I probably fold and try to double my 900 or so chips at a time more convenient to me.

Of course, if the player involved is either of the above, your play is easy.
