Frieght Trains

You're gonna get run over by freight trains now and then. Someone with a pocket pair makes quads while you're going-all in with a full house.

Ouch.

You slow-played your trips only to find out they made full house on the same pair.

Ouch.

There is literally no way to defend against a set, where their pocket pair matches something on the board.

In these situations, chip management is the only thing that can save you. Not having so much on the table that going "all in" bankrupts you in real life.

Being willing to give a few up to someone who's a better bluffer than you. Maybe they don't have quads or a fh. Are you willing to risk your bankroll to find out?

In fact, the only mistake you can make in poker, realistically, is to underestimate what your opponent has in his or her hand.

Feels like getting hit by a freight train.
