I haven't actually tried this but it's something I think I'll try at a low-limit SNG later should it arise.
For example, suppose you limp in cheaply with Axd to see a flop and you catch the nut flush draw with a flop of Kd 8c 2d. The first person to act bets out representing top pair and you call him.
On the turn you miss your flush but another 8 comes on the board.
Again, your opponent bets out with top pair but you raise him to represent trip 8's. Is this a play which anyone has used effectively?
