Hey there - my colleague Jonathan Lessard just released a new Chesslike called Rogess. The essence of the variation is that pieces now have "hitpoints" (according to their traditional value in chess) and thus aren't immediately captured. You can miss too! You've probably always wanted to try to capture a piece and miss it, right? Anyway, if that sounds weird enough to try out, have a look below - it has a mediocre AI or local two-player.
