yup

Well, not always. Remember the kurokiba-haiama-yukihira match in which souma was the last to serve and didn't win... I don't think the author would be so predictable as to make yukihira just lose. Maybe it will be a tie, or yukihira might win (even if highly unlikely) and it will be desconsidered seeing that it was not an official event (shokugeki). I don't know, I'm expecting some twist
So we can guess who's going to lose as this manga has an obvious pattern..
The one who serves(reveals) last wins
