In my opinion TS is just trolling. But I play mostly at an other site and won against players with a rating 300 higher and lost against 300 lower than me. And often because I or my opponent played a good game. How are you supposed to get better if you don't get to see what better is and you run from a fight? The important thing to remenber playing against stronger opponents is that you shouldn't be intimidated and just play your best. Most of the time I don't look at my opponents rating and I just play the board. Complicated tactical positions are your friend. Slow positional games are much harder to win against someone seriously stronger.
And rating is just a number and completely unimportant. What is important,.. enjoying yourself and not 100 wins against weak opposition gives me the satisfaction winning against a much stronger opponent gives me.
