From a Pennant point of view, I absolutely don't want my opponent to play well, the worse the better, but I always expect them to play exceptionally well, and if they've hit a good shot or putt I'll generally always give them the "shot" "putt" etc. I've always found most of my opponents much the same, you get the odd wanker who doesn't tip the hat to anything and doesn't talk but that's fine, horses for courses, on the whole most people are respectful and decent.
Yep, pretty much the case i've found with most players i've come accross as well. Plenty of idiots out there taking life too seriously, but for the most past, most guys want to win and will gladly take you playing badly to get the W, but they will also acknowledge good shots/play.
My regular weekend group though. I have two different directions i take. As I play with the same group of guys most weeks I always want them to play well. However, the flip side to this is if they are having a shocker I do enjoy having a laugh at their expense watching then play their 5th shot still behind the ladies tees, etc.
