I look at it differently. I stated I'd take a 4-point middle, in real time, I would, but won't get it.
Here's how to middle, takes balls ! Find a line like Dallas over 198 yesterday. that's the right side Take early stand for about 5 units, even though you want 1 unit, be confident, let line move 5 points, bet 3.5-4 units when it moves on under. You have good middle.
Original bet usually wins, but you can't risk it losing. Pay Pinnacle, win at other book. Good bet in theory, good middlle, pay Pinny.
