Rich, thanks for your response. Mybe I am misunderstanding something but
your suggestion the capture forward isn't it more like Chinese Chess? I
understand this is in addition to the diagonal capture but the problem is
you end up playing a much more tactical game similar to Xiang Qi
I am unsure of your meaning when you say: 'My take is this approach of
just adding capture forward, is probably the least disruptive. '
It seems to me that the entire nature of pawn play is changed. Compare to
the lateral movement and upper board capture movement of ninja pawn. These
pawns can actually be stopped by other pawns.
Is it is an intrinsic property of orthodox chess for two pawns to face
each other unable to move . Your ability makes it more like Xiang Qi which
is a totally different type of pawn play entirely.
It seems to me like you would like to completely change the nature of pawn
movement rather than just 'balance' things out on a bigger board. My
testing showed that the ninja pawn addition just reinforced the pawns and
compensated for piece over pawn dominance.
