Checkmate in Seven

Earlier this week I won a correspondence chess game played at Scheming Mind Chess Club by checkmating the Black King in seven moves.

We were playing under Chess 480 rules with the starting position of the pieces as seen in the graphic below.

One of the very first things I do when playing any 480 or 960 game is look for any weak, undefended pawns. On the board my opponent and I were assigned, the pawns on my e2 and his e7 were undefended. So while Black was occupied by developing his Bishops, I captured his e7 pawn with my Knight, checkmating his King.

The move record and board at the end of this very quick game are shown below:

1. c4 f6 2. d4 c5 3. Bc3 Bf7 4. Ne3 Bd6 5. d5 b6 6. Nf5 Be5 7. Nxe7#
