so basically what you are asking is, how to focus in live tournaments?
Well, i dont play in USCF but i play in 5 different live tournaments within the last 6 months period.
My trick is to take a deep breath before making any non-book move. Analyse the potential of the piece the enemy in front of you just played. then analyse what your piece can do and what it can bring into your game.
That way, you are less likely to make a blunder. But try not to overthink it. you're bound to lose once in while. I havent lost any white games since January, drawing twice and winning 12. but i lost as black twice and drawing once and winning once. That includes me playing the the nottingham county chess league.
This has been my fifth decisive lose in a row (counting this tournament). I always make careless mistakes and lose these games I normally wouldn't. If anyone on here that competes in USCF tournaments could, please tell me how I can maintain focus going into the last round? All these decisive losses combined with the new USCF policy of limiting the amount one can jump in terms of rating is making me want to quit competitive chess altogether. I really just want to cover the expenses when my dad takes me out on these long rides. Chess is not a sponsored game for anyone below the 2600 mark making this a financially unstable hobby/ burden.
