Saturday's puzzles are now in the books, and they from all the stuff I've read on the TPB and my own personal Twitter feeds, I can report that Puzzles 5 and 3 respectively were the ones that separated the field into the haves and have-nots.
With Puzzle No. 6, Dan Feyer increased his lead to three minutes over Tyler Hinman and six minutes over Anne Erdmann. As of Sunday morning, the rest of the Top 10 is Francis Heaney, Stella Zawistowski, Kiran Kedlaya, Howard Barkin, Joon Pahk, Al Sanders and Jon Delfin.
Glen Ryan is the top rookie in 14th place and could make the B finals. Due to scoring changes, the top native B scorer so far is Robert Mackey, who is in 17th place, with Jeffrey Schwartz in 20th place holding down the possible third spot on the B stage.
Benjamin Coe is the other hot rookie this year, currently sitting in 33rd place. His nearest C competitors are Jeff Davidson (67th) and Neville Fogerty (75th).
Puzzle No. 7 kicks off the Sunday festivities at 9:00 a.m. with the finals set to start after the talent show which starts at 11:00 a.m.
