How many "possible" attacks can be focused on one point on the board? For instance the pawn in E5:

What is the maximum (realistic) amount of attacks that are focused on a single point on the board?

  • KQQQRRBNNNNNNNN so 15 I guess. Just one bishop can't logically participate. – hoacin Mar 11 '17 at 18:23
  • Would you be interested in playing a chess game? I'll send you a link and we can play, I see you are ~2500 – Habbo Mar 11 '17 at 19:17

Not sure what you mean by "realistic".

Basically you can attack it with 8 knights plus 7 other pieces attacking horizontally/vertically/diagonally, i.e. from each cardinal direction (North, NorthEast, East,...) except for one.

For example:

8/3N1N2/2NBQBN1/3RpR2/2NPK1N1/3N1N2/8/8 w - - 1 1

Notes:

  1. At the start of the game each player has 16 pieces of which two are bishops of opposite color. That's why one of the bishops will not be able to attack the square and the maximum number is 15.
  2. In the example 7 of the knights are fixed. You can think of (1) using other pieces to attack along the cardinal directions or (2) replace one knight with a piece attacking from f4.
  3. You can move pieces that attack along the cardinal directions further away from the attacked square but this does not help to focus more pieces on the square unless you count batteries double. In any case you are running out of pieces to achieve more than 15 attacks.
  4. It is possible to get 8 knights and two dark squared bishops through pawn promotion. In the example 6 pawns have been promoted to knights and one pawn to a bishop which together with the remaining pawn sums to 8 pawns.
