  The class of Poset Take-Away games includes many interesting and difficult
games. Playing on an $n$-dimensional positive quadrant (the origin being the
bottom of the poset) gives rise to nim, wythoff's nim and chomp. These are
impartial games. We introduce a partisan game motivated by chomp and the recent
chocolate-bar version. Our game is played on a chocolate bar with alternately
flavored pieces (or a checkerboard). We solve this game by showing it is
equivalent to blue-red hackenbush strings. This equivalence proves that the
values of game are numbers and it gives an algorithm for optimal play when
there is more than one chocolate bar. The checkerboard interpretation leads to
many natural questions.
