latest analysis on the Chee Will o' the Wisp opening

All of the world's best including world champions Miki Borghetti, Sergio Scarpetta and Alex Mosieyev has been defeated in my variation of the Will o' the Wisp opening. This variation first came into use in Kurnik in 2006 by the great master Darion "the game", who defeated legends Juan and Max on the same day with this line. While briefly noted in Kears as a draw, no further play were given in the literature.

I learned that this opening was named after a phenomenon known as the Will o' the Wisp or Jack o' Lantern, mysterious lights seen at night (which is what inspired the Jack o' Lantern pumpkin carvings during Halloween). The phenomenon is known as Dab Ntxaug in Hmong.

This line was picked up through the Russian database program Aurora late in the last decade and improved on by yours truly. Presented here is the most up to date analysis. A few corrections were found by Doron Howard and so far I've incorporated one of his correction here. There should be no major mistakes along the main lines.
