While I lose at WSEX, I win most of the time at Pinny. The only game I lost money at Pinny was the Chi-GB game when Favre threw the INT for the TD - and I lost BIG. How big? Enough to take away profits from 3-4 games where I won.
As far as strategy is concerned, I keep taking + money and not wager after halftime.
I will take Team A +150 for 3 units, buy back at +100 or more for 4 units, take Team A again for 2 units and zig-zag back and forth until I run out of money.
Yesterday, I wagered close to 45 units in it (and never exposed more than 3 units) and made a 3 unit profit. The profit would have been higher, but I was setting up a NE -7/Jax +7.5 scenario.
