On the other hand, I lost my Regionals because I allowed too much laxity in my play against my opponent. If I had been less concerned with being a good sport and didn't allow his takebacks to mistakes I would have won the match easily. I regret playing so lax and have learnt to be utterly ruthless in tournaments henceforth.
This is why on an organizational level "take-backs" should not be allowed during Regionals play. For one thing allowing take backs in a tourney that is likely to have a couple of hundred people at it will extend your playing time a great deal and not in a fun way but for dealing with player errors. If it's the current expectation that "take-backs" are allowed at the Regional level, it is going to take more than just FGG's judges putting their foot down, Different expectations will need to be set from within the competitive community.
