when i shoot someone thats better than me i get real nervous and miss shots, yesterday i was playing a kid that i knew i was better than so i wasnt even trying my hardest and i would run out alot more, the last game i ran out off the break and the kid wouldnt play me anymore. why is that when i play people that are better than me i never get a big run or a run out off the break. what can i do to help me change this
