We are in the 3rd set up 5-1. I'm at the line ready to serve I call the score 5-1 and just as I begin my toss one of the other guys calls out 5-2 so I stop, start to correct him then see him start to laugh just "psyching" me he says - ha ha. Next point again as I begin to serve the other guy calls "time" - he suddenly needs to get his visor. Now I know they are working me and I'm p*ssed. Third point as I'm about to put away an easy overhead I get the "late" out call on my 2nd serve. Well now they got me. I'm really p*ssed. We get into an argument over the score and that's it for me. It will get ugly so I grab my bag and say see ya. So are these "tactics" legitimate" mental warfare" as Brad Gilbert would say in Winning Ugly or is it cheating. Or is it just "unsportsman" like? Does it matter if its a "friendly" weekend game as this was or are the rules different in a tournament? What do you do to deal with "gamesmanship" or on the other hand do you employ it in your game?
