92 ( +1 | -1 )

Making You Think What is the most possible moves by BOTH sides (excluding en passant captures) in any position (x)? There are two catches. The position does not have to arise from a game. You can choose to put the 16 pawns, 4 knights, 4 bishops, 4 rooks, 2 queens, and 2 kings wherever you want. Secondly, the kings cannot be in check.

The position must be a legal position (e.g. no pawns on the [1/8] ranks)? [No, pawns cannot be promoted already.] Can anyone find a position with more than 60 possible moves? 80? 100?

We could have a contest in which you tell how many moves your position has. If someone accuses you of lying, you can actually show where the pieces would be (Rw@a1) where 'w' stands for white.

I know this contest seems difficult. But I urge you to try to find a position with a lot of moves. Set it up on a chess board.

Now, see if you can beat me. My record is 88 different moves from BOTH sides. See if you can beat it.

-Good Luck

88? Must be much more. If I place 8 rooks in a diagonal (i.e. from a1 to h8), I get 8x7x2=112 moves (nr of rooks*nr of available squares on 1 line * the number of lines a rook has).

I think that placing 8 queens so that they could not capture eachother is even better. One way (of the 92 ways) is to place them on:

a8, b2, c4, d1, e7, f5, g3, h6

which would lead to

21+23+25+21+23+25+23+21=182

There may be queen formations which have even more possible moves.

but I would get more moves per side with

4 white + 4 black queens :)

if queen values are dealt as follows

color a

21

23

23

23

color b

21

21

25

then color a has 90 moves and color b has 92

AND even if I have to place 2 kings to get a legal position (without a check), I would end up with 89 moves :D

to be precise 89 for color a

91 for color b

like I said before, there may be better queen formations amongst the 92 possible ones than this one.

Yes Read the first post carefully javelin: no pawns have been promoted, so there are no additional pieces!

Kind Regards,

very nice puzzle i scored 210 with all the given rules. However it is not possible for this position to come out from a game.

I think that it can still be improved...
