It's official. 9 am start times are too early. Round 4 I was paired against a teenage girl rated 1569. Don't know if it was the early start, the 350 point rating difference, hubris, or eagerness to go explore, but I was playing too fast. I had a worse position, a blunder turned it around, and then I messed up the winning endgame and the game ended in a draw.
This game concludes my Land of the Sky tournament as I withdrew so I can go explore a little bit of Asheville before leaving. I have two weeks before the next tournament so I have time to put some study time in.
