Cool miniature ending in 11...jump@c3 Bxe1#

Here is a cool 11-move checkmate by black that I discovered when analyzing for the team game.

1. e4 c6 2. Bc4 e6 3. c3 b5 4. Bb3 c5 5. Qf3 Qe7 6. d3 Bb7 7. Qg3 c4 8. dxc4 jump@e6 Qxe4+ 9. freeze@e5 Nd2 Bb4+ 10. Nxe4 freeze@d2 Bxe4 11. Qxb8+ jump@c3 Bxe1#

Review the game move-by-move here.

White blundered with 9. freeze@e5 Nd2.

Is that what was played or is that just an example

8. Na3 was played in the team game. The above is an example of how black can win quickly if white goes for 8. dxc4 instead and blunders with 9. freeze@e5 Nd2.

Oh ok
