The "Sucker" defense is a very fitting name for this defensive formation for which I gave it to. In all my years of playing, I have never heard the term used by any one else, nor have I seen anyone use this type bold defensive maneuver. I guess one might say, I am the owner and creator of this defensive formation. But seriously, I know this defensive concept is nothing new to the defensive world of foosball. In fact, This defensive concept is commonly referred to as a "bait defense" and is used all the time by many well experience players.

A Bait Defense can be defined as:
Any defense which opens an enticing hole to the offense; the defender ideally predicts the offense's timing and closes the hole as the shot begins, or even before it begins. The bait defense may be moving or set. If the bait seems to be set and very obvious, this is also known as "fishing".

the idea behind the sucker defense is to entice the shooter to shoot into what seemingly is an open hole

This is very bold and aggressive defensive way of playing goalie. The idea behind this defensive maneuver is to take the ball away from the shooter by getting him or her to shoot into an open lane. Aggressive goalie players who want to take control of the shooter's game will use this type of defensive scheme on a regular basis, especially against the inexperience player.

this defense requires great intuition and timing for it to work effectively

The "Sucker" defense takes a long time to master.  A lot of factors are involved when using a this type of defense. Things like timing, very good intuition, reading body language, and early shot type recognition, all play a major part when using a "Sucker" defense. So, do not get discourage at first if it does not work for you at first. The more you play goalie, the sooner you should know the right time when to incorporate a "Sucker" defense into your defensive scheme.
