In answer,
Not always (you're still looking for outcomes)
Depends on what the actual odds are
It's hard to say but I played
Aston Villa Vs Burnley today
And I'm playing Real Madrid Vs Villareal now.
Which obviously both won with just bet 1 which wins me £36 per time less commission.
I am making this too easy!
From what you say about winning £36 if Bet 1 wins, I take it that £36 is your 12% ROI profit and you play on games that are around 3.4 to lay 0-0 at HT and around 15.0 to back 0-0 at FT.
