I have uploaded the 13th round games with Fritz-notes (some courtesy of TD Geoff McAuliffe), my opening pointers & color-commentary.The most interesting moment from Thursday occurred in the Joe Renna-Ted Mann contest. As you can see (below), Ted missed a winning discovered attack combination :

after 11.Bd3??
Black to win
...that, in essence, was identical to one he missed against Shiffman in round 7! :
Shiffman-Mann

Black to win
It was, as baseball great Yogi Berra once said, "deja-vu all over again"!!
Here are round 13's Java-replay & PGN links.
