    Rule reminder

    Pawns and Pinces can make a (non-capturing) double forward step on any rank, and can always be captured en passant on the square they pass through by an opponent Pawn.

    Several pieces automatically promote on reaching the 14th rank, without choice. Pawns promote to Queen, Princes to Amazon, Knight, Camel and Giraffe to Buffalo and Elephant, Machine and Centaur to Lion.

    Trolls promote to Queen when they move from 13th to 14th rank.

    There is no castling, but an unmoved King that is not in check King can jump to the second ring if a geometrically shortest path to its destination is not under enemy attack.

    For playing through the sample game discussed in the book, go to the game viewer.

    Checkmating

    Only the Knight, Bishop, Camel, Giraffe, Elephant, Canon, Crocodile, Sorceress and Rhinoceros cannot force checkmate on a bare king. You can practice checkmating with them on the 16x16 board here. (Beware! Building the End-Game Table can take a minute or more for this large board.) Although there are checkmate positions with a Machine, the board is too large to force those when the bare King is not already trapped in a corner. This also holds for the Prince, but since this can promote that is a moot point.
