About this position
This mate is named after Samuel Boden, an English player, who delivered it in this game against Schulder in London in 1853. He was not the first: an earlier game is known, Horwitz against Popert, played in Hamburg in 1844. The pattern is easy to spot: two bishops crossing on different diagonals, like a pair of scissors, in front of a king that has long. For it to work, the squares around the king must be taken by its own pieces, which take away its exits instead of protecting it. What to remember: if you castle long, watch the diagonals that reach your king, and do not surround it with pieces that block its way. A king with free squares is much harder to mate.
