Relagging when hill-hill is totally pointless and goofy. Work out the possibilities in a race to two that goes hill-hill. There are only two possibilities of wins and losses: WLW and LWW for the winner. The player who won the initial lag will always have exactly one more break than the other player in a hill-hill match. The only thing that the relag might do is take the break away from the person who lost the lag in the first place.
Here is how that works:
A wins the lag
A breaks and wins, score 1-0
A breaks and loses, score 1-1, hill-hill score, time to relag
Relag, A wins the lag
A breaks for the third time because he won the relag. Maybe he wins and maybe he loses the game, but he got all the breaks.
Does anyone really think that's fair?
