Hi jyrki!
I noticed that you suggested a more efficient way to tackle yesterday's tough puzzle than the one I posted in the blog.

I have added the proof you suggested to the blog proof for that puzzle.
Thank-you!

Reminds me of the car show at the Orchid Hotel in Chiang Mai last Febuary.

I made a comment a few hours ago but it seems to have vanished or else my belief that I hit the 'Submit Comment' button actually happened in a dream. ANYhow, Easy puzzle today. My full analysis is on the blog. Felicitations to all (again). Cool antique car

19:27 - Pretty Easy; did have to guess once. I need to check out the daily proofs some people have.

15:28 Fairly normal for a hard. I don't think this one was a tough. Nice car picture. My guess is that it originally was black.

My first 'TOUGH' solve! But I have to admit to one guess. I just couldn't seem to find any forbidding chains.

Morgan, I had a comment disappear the other day -- I think it was on MEDIUM. Weird...
