I know looking at the results the accumulator would be the most profitable by far, but this was only due to todays winners. Again the same thing with the single to win. Would it be worth be placing these bets in the hope of catching the big ones like today, or just keep it steady with the place bet? I have no read experience with accumulators. I am betting 10% of my bank daily, so would it be worth putting 8% on place and 2% on an accumulator, or would the return not be worth the outlay? Thanks. Adam
