Dropped a piece on something like move 7 because I was playing like it was G 15/0.
Thoroughly drove home Heismann's point that intermediate length games hurt more than help.
I believe I fought well and vigorously, but my opponent did not make any mistakes and hanging my rook (vs rook and bishop) with ~5 minutes on the clock sealed things up.
In spite of that (or perhaps out of necessity due to a player being wholly unavailable), I will be playing next week.
I will not embarrass myself like that again.
