Sometimes, when an element of surprise is wanted in an RP, someone will go to Chatzy and type in /choose.
The /choose function of chatzy is common in Warflame RP's. Whenever somebody wishes to attack someone fairly, they will often simply give a 50/50 chance (/choose hit, miss). Whever somebody attack someone with a likely chace, they'll make it more likely. How this works is that they add another hit or miss depending on how much more or less likely they wanted to make it.
