3/6(6-max): Turned flush draw, disguise/build pot

[AceHiStation]

Been playing a bit at the table with a fairly TAGgish image. I felt that even though I only have about a 19% chance of hitting the flush on the river, but I felt if I did hit it, I could easily get paid off bigtime by a straight/two pair/flush. Just curious to hear some thoughts on this line.
