Imagine if all the time some people spent combing through rulebooks looking for a technicality to help them win, would be spent working on their games or game strategy instead.....
I was in a tournament once where the dresscode rules were so strict that patterns or marks, even on black dress socks were not allowed...I had to go home to change trouseres because of some thing about the pockets on my black trousers were not up to the code. I know, the idiocy of such rules are beyond imagination. I considered dropping out after that, but I'd allready paid quite a bit for the entry. Anyway, a player was losing and noticed a tiny pattern on his opponents black socks, and won that way. I bet if he was winning he wouldn't have bothered saying anything.
Here's the thing about rules: They need to be kept simple and common sense, otherwise they tend to get abused and inadvertently violated. The biggest problems usually occur when just one or a couple of rules are suddenly changed from a long standing rule set, and the change is adding something rather than subtracting. Sadly, often the seemingly least important changes have the biggest impacts, because people forget them. Rule changes like these happens because the promoter has some sort of pet peeve, and not for the good of the game. And of course, the victims of these rules are often the most seasoned and best players, who play on autopilot. The winners are the people combing through the rulebooks.
