Trips on a flush board, forge ahead? ($22)

With the logic that you're using, and that's assuming that this guy made a standard big bet to push people off draws because he's got a high pair, you're better checking to him to extract more chips from this guy buy the river. At this point it's all about making more chips, rather than bluffing this guy out since you're sure he won't beat you.
