Allin every time right?

[Poker Fool]

it is not about hero being scared, it is about villians getting scared.

Say one of them has AK, he does not hit the flop and gets away the majority of the time.

One of them has KK, an ace falls and he shuts down.

Maybe one of them has QQ, then a King or an Ace frightens them.

Just get the money in preflop before the villians work out they are behind or fear they are behind.

If you get the pot heads by pushing, then fine, dead money has been created and your a bigger favourite to take the pot down at showdown.
