Of course, some of the standard opening from the Encylopedia of Chess Openings (ECO) end in a checkmate, at the end of the opening definition! [Event "?"] [Round "?"] [Site "?"] [Date "????.??.??"] [White "?"] [Black "?"] [Result "*"] [ECO "C44"] [Opening "Scotch"] [Variation "Sea-cadet mate"] 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. c3 dxc3 5. Nxc3 d6 6. Bc4 Bg4 7. O-O Ne5 8. Nxe5 Bxd1 9. Bxf7+ Ke7 10.

Nxf7 Qxg2 6. Rf1 Qxe4+ 7. Be2 Nf3# Interestingly, in the current analysis project, at least one possible checkmate has become visible from the analysis of current standard openings (other than the trivial ones listed above). I rather suspect that there will be more.
