Square Free

[TimeSpaceLightForce]

Remove 4 pieces from the above position.. then place them back on any free squares of the chessboard  so that no square can be formed by any four pieces on corners of a square .  Which pieces to choose and where to position them?

 

Spoiler

This is base on my posted question : " Anti Square" .About most number of pieces on chess board without forming a square. Yet 34 may not be the maximum.

Thanks plasmid - didn't use that particular tilt before!

BTW, a4-d1-d7-g4 in your figure forms a square.

Replace {a1, c2, c3, d3} with {a4, b3, g2, h7}.

 

[rocdocmac]

Two solutions. Maybe more?

It comes from a typo.

Replace {a1, c1, c3, d3} with {a4, b3, g2, h7}

.

 

[DejMar]

Spoiler

Yet not a solution due to {b3, d6, g4, e1}.

Appended post to previous.

A possible 3rd solution! If not. I'm giving up!

@rocdocmac

Your 2nd solution  is the only position I thought  possible. plasmid almost have it if he made adjustment  of  "d7"

Salutes for your 2 more solutions!
