In keeping with the trend lately of examining (or re-examining) fundamental concepts, I wanted to kick around some thoughts on tricks. Most of these are opinions I've held for a long time, but they've been put into a new context recently, so now I get to put these thoughts out here.
Usually when someone is describing a trick that they have, they're talking about one specific set of motions that they do that usually ends up with them striking their opponent. It's usually a set of motions that has a reasonably high success rate, or at least that the fighter perceives as a high success rate. It's a set of motions that they can train repeatedly, and can become very fast and smooth; they're basically setting up a macro that they can execute at whim.
If someone is describing a trick that someone else has, the definition is usually similar - a specific set of motions, a thing that they do, that works most of the time.
I think that both of these are problematic areas of thought to fall into. It's not the training that's the problem - most every fighter that I know has a number of go-to attacks or setups that they use, and a lot of those have turned into signature actions. This person's stutter step, that person's blade displacement on a lunge, that other person's wrist-roll on a cut. Those are all totally reasonable. The problem that I see coming up a lot lately is when the concept of the trick exists in a vacuum, and isn't based on sound fundamentals.
To put it another way, it's not the concept of a trick that I think is an issue, but it's the thought process behind it. If you don't understand what you're doing and why it works - if you can't describe how your trick is playing with measure, or deceiving the opponent, or whatever - then it's not adaptable. You're stuck with this one thing that you can do super well, sure, but it's not really adaptive if the situation changes. I think that the fighters I know who have a few bread and butter shots (and man, now I need a better term than "trick") but who really grasp the core concepts of fighting are insanely dangerous, because they can change up those shots on the fly.
Now that I've written this down, I'm not sure where else to take this (other than to say, "Hey! Learn your fundamentals and also be sure to drink your Ovaltine!") but I'll probably mull this over in my head more.
