[adhwmpxx] Games with no bad moves

A chess game with no bad moves, or for which all the bad moves have been annotated with question marks, is a weakly good tool for study and learning.

If bad moves were not annotated, then the student might get confused trying to figure out why a certain move is good, when it actually isn't.

Go through the (good) moves of a game.  If any move strikes you as bad, try to understand why it isn't.

It is only a weak learning tool because it cannot tell you if some alternate move (that wasn't made) is good or bad or why it is good or bad.

Of course, many such game collections exist.  Ignore the exclamation annotations: they are useless for study.
