I find myself making weird river bluffs like that thinking my line is "bet-fold" on the river. Do I think it's a good place for one? Not really. In the long run I think you're going to lose here.

Here's a recent hand of mine where I made a stupid bluff on the river, but it worked!

Party Poker 0.50/1 Hold'em (6 max, 5 handed)

Preflop: Hero is BB with , .
1 fold, MP raises, 2 folds, Hero calls.

Flop: (4.50 SB) , , (2 players)
Hero checks, MP bets, Hero raises, MP calls.

Turn: (4.25 BB) (2 players)
Hero bets, MP calls.

River: (6.25 BB) (2 players)
Hero bets, MP folds.

Final Pot: 7.25 BB

Since he raised pre-flop, there's a good chance he has a pair here and is calling down. And if he doesn't, that river completes a straight for KJ - another likely raising hand. Yet I bluff him off the best hand. I don't think I'll even be successful 10% of the time in this exact situation.
