We are always admonished that to blunder-proof our chess, we must search for checks, captures and threats on every move, for ourselves and our opponents.
This is not so easy to practice — how do you know when you’ve missed something, except when a gleeful opponent swoops in to take an overlooked loose piece?
The answer is now at hand:
Here are two sets of positions selected at random moments from a selection of master games.
The FIDE Elo rating system began in 1971. Elo did a bit of study trying to work the ratings backwards, but the chief scholar in this regard is Jeff Sonas http://chessmetrics.com/cm/.

This year, as usual, we discussed a series of topics suggested by
members, including an Opening Workshop, Creating and Exchanging strong
pieces, Making and Meeting Threats, and Endgame Elements. New material
