Done. Tough hard expert, made me work for every digit

this is a tough expert

green and many guesses

puh!

real slow starter -- first pass only got one item filled in.

Decided to use the sudokuwiki solver to help me understand a puzzle this nasty -- the keystone proved to be a WXYZ-wing, which from my perspective is nothing more than a shortish guess.

tough puzzle - finally got it with greens.

brutal, brutal puzzle. only 2 cells with 2 options. Im sure I can add a few but I see multiple guesses coming. Dont even know where to guess....Did I say Brutal

four guesses

Gonna drop off the elite list while I try to work this one out ..
