dark_j3sus, Not really, there's nothing magic about chess. If it was solved then you'd be able to make perfect moves just as you can make perfect moves now when there are 6 pieces (thanks Loomis) or less on the board by using a endgame table base.
1315checkm8, this is likely but not necesarilly true.
A "perfect" chess game (perfect by both players, or else it's not really perfect) would have to be a draw, and I don't see how you could argue otherwise. White having an extra move wouldn't matter; that extra move isn't enough to force a win, even with perfect play
