What is the most defended structure? Let's say the opponent has no pieces on the board but you have all of your pieces. In what way should you place your pieces on the board so that you have the absolute maximum of support for each piece?
Supporting/defending the king doesn't count and it doesn't matter what color you're playing. There is a +1 point for every protection a piece gets. X-ray protection doesn't count. Doubled pawns are allowed (even tripled and so forth). Bishops have to be on opposite colors.
This puzzle needs more love, so I post my best position (46):
[FEN &quot;8/8/2PN4/1PKB4/2PRNB2/2PRQ1P1/3PPP2/8 w - - 0 1&quot;]

Since just a record attempt is hardly an answer, here some tips for those who want to beat it:
R (and less so Q) are no problem, just put them in the mid of the fray. B can easily have at least 3. K should also have a crowded place. Critical is to have many covers by N and especially by P. Do not bother to count how often a piece is protected when moving around stuff, rather count how many pieces it protects!
