Interesting gameplan, sticking to a particular scoreline.
It reminds me of a betting shop strategy I had with an old mate of mine. This is going back 25 years before internet betting, when you could only do a 5fold if you included home wins. However, this didn't apply to correct scores
We noticed the majority of matches with a team winning, often ended either 1-0, 2-0, 2-1
Therefore, if we picked a treble of teams we thought would win and permed 27 correct score trebles from those scores we may win. It worked out at between 10/1 and 16/1 when a treble came in. We had a few brilliant winners, but we became over confident and started raising our stakes and became bored after a few losers, especially considering 27 bets was a significant outlay for young lads looking to get pissed and laid all the time. But, it was a cracking winning strategy when we were disciplined
