    Since the first color was right between blue and green, I refused to choose one or the other. I'm not gonna play that game.

    Another lens is ii7-II♭7-IM7 = ii7-V7♭5♭9-IM7, viewing the II♭7 as an altered V7. This would retain the same 3-7 (just flips them).

    You get e from the primes by averaging the set size of only growing gaps (2,3,5)(7,11)(13,17)... or only non-shrinking gaps (2,3,5,7,11)(13,17)(19,23,29)... Not a property of prime…

    This is already incorporated to some extent. Keeping in mind sets vary, Knight's profile is the L-shape. Rook has four parapets (and four gaps). Bishop has a diagonal slit. King ha…

    Chess.com seems to have excellent opening instruction. It actually tells you the opening name as you play. After you play, it gives you more. It shows where you screwed up, gives y…

    After reading the complete Shakespeare, it is a natural continuation to go on to read the complete Milton. Outside the core of Paradise Lost/Regained, Samson Agonistes is another g…

    CAPTCHAs are used as a literal Turing test; that's their whole purpose. From the get-go their usefulness window had a looming expiration date.
