But isn't everyone just going to call one more bet if they put one in already? Then you're still 6 handed but any flop bet gives better (well, 6 handed it would be correct) odds to chase a draw.
At 50-$1 betting into the crowd is about useless in the BB. No body is folding PP to a single raise, if someone will reraise you than it is worth pushing to maybe knock someone out. You almost need a minimum of trips to take down a hand with all those calling stations.
I didn't raise, preflop, because it would have shown the strength of my hand and given me limited advantage. Not raising got me 2 extra bets on the river, which funny enough would have been the extra if I'd done it preflop. So what was right is anyones guess.
If he raises, not 1 person will fold to an extra bet. Like you said, he would need a limper to reraise for that to happen. All a raise does is build a massive pot.
