I tried the zillions file, dwarves against humans, playing the dwarves.
It's stated everywhere that the soldiers may capture diagonally as well as forward, what would make them incredible strong for a front line.
(Normally it should be no problem with that army to win against fide, as it's completely stronger)
In fact in this zillions implementation it's not possible to capture diagonally, what i assume to be a programming failure, hope you could change this soon
