One can view the B-Class version of IAGO Chess as an attempt to have an 'open-source' variant of Seirawan Chess, using the more traditional pieces, and also framing the rules so they are more variant friendly. The fullness of the rules is a framework for integrated variants into IAGO also, so that is a plus. There is only one new rule added that is more of a statement of what variants should be, make sure your pieces and rules mix. In other words, don't do like standard chess that can theoretically allow people to have 8 queens, but only provide one with the game. And do regular chess rules say anything about flipping a rook to give you another queen?
At this point, I am not worried about Seirawan Chess. I will be going with IAGO Chess. If Seirawan Chess people happen to want to do anything with IAGO, they are free to get involved.
