@allafleche Am a bird if your feather. I had a similar concern, but when I tried playing the U1500 tournament I did win several games. And learnt that:
1. You should not let rating points scare you.
2. Play noobs all the time and you will never develop resilience. Play tougher competition, it will toughen you up.
For example, I normally enjoy pulling the center fork trick to all noobs players am paired with. But when I played a higher rated player, s/he picked my f7 pawn (sac'd a bishop) and it was downhill for me....sac...check....check...mate!!! :-)
But I analysed the game and learnt a tone of options I had.
So take the challenge. Beat a 1400+ get many points. Get beaten, what do you loose?! It's only a game!! You will get your points back in your noobs zone anyway!
