I don't think that there are any dead stones left on the board because everything has the potential for two eyes, but is this true in all rulesets? Would the blocks of white that I labeled 1 and 2 ever be considered dead? Thank you very much for the input.
EDIT: Actually, on further review, I think that the white stones in the center, where are made the two green circles, are dead and all of that territory belongs to black, including the white stones.
EDIT2: And I believe that the red circle I made in the upper right should be neutral.
You're right on the edits. Also I think Q19 should be neutral if both passed, but if not, it depends on who plays first. If black plays, he can capture a stone. If white plays, the stones are connected.
As for 1 and 2, 1 has three eyespaces, and therefore has at least two eyes. 2 has two eyespaces, and has two eyes because of that. Both can't be captured unless white passes indefinitely.
