if we implemented the pi rule instead of the komi rule for go, what would be your first move as black?

Perhaps it would be a good idea if you told us what the pi rule is.

I would guess, he means the "pie rule" instead: http://en.wikipedia.org/wiki/pie_rule. The "pi rule" (w gets pi komi) doesn't seem to make much sense... ;-)

I'm sure any pro player as the second one to move will choose to swap. It even feels like a possible move to play as black with usual komi. In my feeling, the first move on the second line will be slightly better for black, and on the first line will be better for white.

I have no idea. The last time I brought up the topic most people wouldn't make suggestions: http://lifein19x19.com/forum/viewtopic. ... &hilit=Pie

If you forced me, I guess I'd pick 2-8 or something.

The only difference with komi 3.5 would be that you win by 0.14159... instead of 0.5, but the .5 doesn't make more sense. Personally I prefer saying "3 point komi, white wins ties"... Or just leave the ties be.
Imaginary komi, now...

If that is what is meant then I would think that e is a much more widely used number then pi and so we should have the e-rule. It would also me more apt for e-mail games, I guess.

And since both players can say it... Both players win?
That's an interesting interpretation. (Shame it only works in English)

If one is looking for ideas to replace komi, here is one. Play two games with alternate colours. Add the results of both games. The palyer who has the higher total score wins. The first game is a bit different from traditional game, because one might settle to lose a little instead of taking a big risk. But the second is not. A similar idea is been used in football, ice hockey, etc. matches.

Seems good for black.

How do you score resignations?

I assume a resignation would be for the entire match - that is, the first game is played until the end whatever happens.

It might also make sense to equal a, say, 50-point defeat with a resignation. This way, you might catch a draw by crushing your opponent in the second game even after resigning. But since players would never resign the first game anyway, I don't think it would change much.
