Process

Blunder check

You might say: final safety scan, pre-move check

A blunder check is the last deliberate scan after choosing a move: re-read the opponent's checks, captures, threats, loose pieces, opened lines, and tactical counters in the resulting position. It is separate from the deeper line that produced the candidate.

What it does
Catches the one-move refutation that survives an otherwise plausible calculation.
Ask
After my intended move, what is the opponent's strongest check, capture, or threat?
Trouble
The player stops at the attractive endpoint of a line and never tests the actual position after the intended move.
