check
Let an agent explain check in chess, relay rules, notation and related tactics from chess rules and literature, describe perpetual check and cross-check, and distinguish check from checkmate, stalemate, discovered and double check, and the ice hockey foul called cross-checking.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.
