I never memorized move sets. Tried a few times as a teenager.
But I always had a simple strategy: contrarian. That's most of
it. I ask myself, "What am I expected to do next? Which move can
I make that they would least expect?" Sometimes I have
additional criteria with strategy but that's the 'gist' of it
right there. I don't always do "least expect with most benefit
to me" because that's in the set of "expected next" moves,
especially with rational players. I can usually hold my own in
several matches. win-some, lose-some. == Played chess in school,
especially summers. With a computer in the late 80s/early 90s,
spent more time with Battle Chess and got pretty good at it back
then, playing with friends as well although I slacked off
through the years, but any time a game came up, I'd play on
occasion. ==
