With respect to an illegal move, my position is-if neither player observes
the illegal move when it is make and the player who didn't make the
illegal move touches his piece in the process of moving after the illegal
move has been made, the game continues. Having said that, I believe that
it is neither players' obligation to see an illegal move, and if they
don't the game continues.
This rule should apply especially when a player is in check and neither
player see's it at the time, but observes it a move (or several moves
later). With respect to resconstructing a poaition, this can only be done
if both players agree the reconstructed position is the right one.
