The Last Move: White must make the last move--if necessary, an additional pass, with a stone passed to the opponent as usual. The total number of stones played and passed by the two players during the entire game must be equal.

My question is: What if white passes first. Then black passes. And then white plays a stone on the board. Would that be illegal by white?

No, just unusual.

I thought if both players pass consecutively the game is over, and if one player wanted to place a stone after this they’d have to allow the other player to play first.

to give the same result with territory or area style scoring.

The reason why I am asking these questions is because I am working on a ruleset of my own. In this ruleset you have to play dead stones out. And I think I realize now that you have to do like this:

black passes - white passes - game over

white passes - black passes - white passes - game over

white passes - black passes - white plays - game continues

white passes - black passes - white plays - black plays - white passes - game continues

white passes - black passes - white plays - black passes - white plays - game continues

If, in a new ruleset, you have to play dead stones out, would it be best to FORCE white to pass an additional pass instead of giving hir an option to play on the board? I mean, what is the purpose of letting white play on the board again? Black isn't given that option.

Are you suggesting black pass force white to pass? That could be bad if a point was missed by black. I've had that happen... so white should be able to take it.

But white didn't take it the first time. So white has already wasted hir chance.

Ok, so you're suggesting a rule that when black passes after white, white is forced to pass. I guess the only issue to me is that it's really not needed for any purpose. White will pass and end the game. (until Bill Spight comes and finds some odd endgame scenario )

I thought you were suggesting white plays, black passes, and white is forced to pass which wouldn't make any sense.

The first oddity that comes to mind is white passing after black wins a ko fight. Black does not need to fill the ko because his pass will end the game, and all stones on the board at the end of the game are alive. In theory this could lead to a situation where black has more ko threats than white has legal moves, so a one eye+ ko shape group lives.
