I know the has been a lot of opinions on this subject, so why not throw mine out there.
Slow rolling, three betting, check raising are some that come to mind.
Folding to me is the most powerful play in poker. Money not lost is money made and it's free to do it.:deal:
I respectfully disagree.
Folding may be the most important move, but not the most powerful.
Folding is passive. Folding stops play, but it does not apply force.
Saying folding is powerful is a bit like saying not getting out of bed in the morning is living. Sure, you do not risk getting hit by a car, getting mugged, or otherwise injuring yourself, but sleep is merely the pause between bouts of living.
IMO the most powerful play is the Check-Raise.
This is the play which turns the tables and where the roles of predator and prey reverse.
This is where the aggressor finds himself realising there is a stick attached to that carrot he's been chasing.
The check-raise induces that whoa-hey-hold-on-a-minute reaction in the aggressor.
I love that look when they stop...think...oh-wait, what have I got myself into?...
If they flat call, they are now ripe for attack on the next street...like a one-two combination punch.
But, more often than not, they realise that they have been played and they chuck in the muck.
