I have always believed in the "Secret Techique".  Perhaps not a technique that only one person has ever seen it, but rather, of relative secrecy.  The idea is that the less know, and wide spread a technique the better it tends to work while used in competition.  The more the technique is seen, learned, taught, spread and used, the less effective it becomes in a sense as the awareness for that technique is ever growing.

It's like Penicillin and Bacterial Infections.  The drug's usefulness is nearly depleated as it was used so regularly at one point that most Bacteria developed a resistance to it and have thus become somewhat innoculated.

I feel that this same type of thing can happen to your favorite moves.  So I tend to stay away from my best subs as much as possible so that when it's fight time, there will be a high likelyhood that my opponent will not have seen my sub or it's set up before our meeting.

For instance, one of my best set of moves comes off the Backwards Upsidedown Triangle from the Kimura Submission Staging Site, but I try not to use it.  I keep in up my sleeve for when I need it most, and instead use the Arm Triangle Cirlce of Doom from the same Staging Site so that the Backwards Upsidedown Triangle series maintains as much of it's potency as possible.

Does anyone else here use this same type of strategy?
