I guess I go with consistency, although its harder in online play than offline. Not sure if I'm better than average at figuring out peoples patterns, but that is usually key to winning. If you are predictable, you will probably get beat unless you are really good at what you do.
Not great at holding serve all the time. I think when I played jlan I had one service hold, but three breaks. Don't really have a reliable go-to plan. Not so great at the net online as well.
Also good at trolling people by winning with Bouchard ;D
