OT: What's the significance of your 2+2 username?

[TeckChavez]

I played DeltaForce as DingChavez back in 98, he was a character in some Tom Clancy books. When RainboxSix came out everybody new the nick and it lost its obscurity. So I changed it to TeckChavez, which stuck with me through my Tribes and Tribes2 days. I kept it when I started playing poker and used it for my 2+2 nick as well. At the time I registered, I didn't realize that your 2+2 nick should be different than your PP nick but at the level I am at I don't think it makes a difference.
