  If this is true, then I agree with you.  I do not have enough experience with
draughts to claim anything different.  Fair enough.

  That is the correct term.  However, go in my amateur level experience,
requires a high level of tactical calculation in many other kinds of tactical
situations as well.  Most of the time when I play I am working through concrete
variations, but at higher level that may be less.  It is also possible to play
go quite well on just "feeling", if one has some experience with the game.  OC,
then the play is weaker, but it is not necessarily disastrously so.

  I am not really challenging your claim, I am just interested in why you say it
and how you came to the conclusion.  I think your points above are good enough
for me, and I'm content to let the matter rest.

  I agree with that, too :)
