Winning Against Players Who Never Fold

The only thing WORSE than a player who never folds is
someone who doesn't know how to BEAT a player who never
folds...

C'mon man, the answer to this is EASY!

GO ALL-IN.

That's it.

If you've got top pair and your friends at the table are
chasing a straight or a flush, put them to a decision for
all their chips.

You said it yourself... you "usually" win.

Any time your odds can be described as "USUALLY", don't be
scared to push your entire stack in the middle.

Period.

If they call, great. You'll "usually" win all their money.
If they fold, that's good too, because you still won the
hand.

Oh yea, and one more thing...

Quit being such a baby when you lose. You'll never win ALL
THE TIME so just get over it already! ;-)
