are there any stones dead in this game?  My opponent put an x on all
mine and I declined. Since a stone (or a stone group) is called a dead
group if it cannot be saved from capturing by the opponent, shouldn't
all squares be left alone with no 'x's' anywhere?  I'm so new at this
game....

here is what it looked like with all stones marked dead

that just doesn't look right to me  ;)
