CheckerBored Too

Designer: William Waite
Goal: Fit all five pieces into the tray so that if the empty spaces were colored in, a checkerboard pattern would result. Diagonal half-squares are allowed. Solve these three challenges:

• ANTI-SLIDE. Place the pieces so that no piece can slide in any direction (with no symmetry). "Slide" is defined as moving a piece one entire square length so that the pattern of squares remains intact, but the relative color patterning changes.
• SYMMETRY. The pieces must form a symmetrical shape within the tray (with slide).
• SYMMETRY + ANTI-SLIDE. The pieces must form a symmetrical shape within the tray and be (at least theoretically) anti-slide. Though there is some wiggle room, no piece can slide an entire square length.
