working on a problem with maximummer-an important question...


I'm examining a maxi move with take&makechess(non-wcct related!). as you know a complete move involves a capture and then an additional move. consider 1...bSa1xwRb3-b1. Is the overall length of the combined move 1 or sqrt(5)+2? (starting sq to ending aq OR adding both vectors)?

Similar question can arise in moves of pieces like double grasshoppers. Is the total move length to be considered or the distance from starting to ending square. I think the second option is correct.

I second the second option too!
But need to see how winchloe and popeye treat it...

As far as I remember Popeye takes the euclidean distance between departure and arrival squares.

It is easy to check. Consider a position with wPc3 and bSd4. To find the longest move use the following Popeye code:

stipulation h~0.5
pieces white pc3 black sd4
condition WhiteMaximummer Take&Make

"h~" is "help anymove". Note that European users will need to use a comma, as follows: "h~0,5".

If the total move length is used then all 8 moves would be returned. However Popeye gives the following, which are the two moves with the longest distance from starting to end square:

1...c3*d4-f5
1...c3*d4-e6
