Seirawan Chess

Adds the Hawk and the Elephant

Two extra pieces wait off the board and enter as you develop. The Hawk moves like a bishop and a knight; the Elephant like a rook and a knight.

How it plays

  • 1

    The Hawk and Elephant start in your hand, not on the board.

  • 2

    When you first move a back-rank piece, you may place one on the square it left.

  • 3

    Each new piece may only be introduced once.

  • 4

    Everything else follows standard rules.

What the lights do

Squares eligible for a Hawk or Elephant placement pulse cyan while the piece is still in hand.

The rules and the install path are designed and wired up, but the sketch hasn’t been written yet. Everything on this page is real except the binaries themselves.
