# Dissection of a chess board into 4 congruent pieces

Consider a standard $8\times 8$ chessboard where a pawn is placed on each of the squares $d1,d2,d3,d4$ . Dissect the board into $4$ congruent pieces (reflections are allowed) such that each piece contains exactly one pawn.

Do the pieces have to be connected? – Mark Bennet Dec 22 '12 at 19:33
@MarkBennet: The problem sheet on which I found this problem is ambiguous but since the original formulation of the problem talks of a field which is supposed to be partitioned among 4 brothers I guess one should assume that the parts should be connected. – Dominik Dec 22 '12 at 20:36
Print out the diagram and draw the lines ... Top pawn has to be joined to the square to the left. Square to right of top pawn needs to be joined down then left ... other central squares follow by symmetry. – Mark Bennet Dec 22 '12 at 23:07
Try spirals that grow from each corner simultaneously. – Greg Martin Dec 23 '12 at 1:27
