Polish middle is the opposite of hitting a good middle where you win both bets. You lose both of them.

Say I have the Jets -3.5 at one site and the Dolphins +2.5 at another site. If the Jets win by 3, I lose both bets. This is ordinarily awful to take. If you are getting the odds of lets say Jets -3.5 +180 and Dolphins -2.5 +100, thats an 80c arb and an expected return of ~$400 guaranteed profit on a $1000 bet on each side. So you are risking 2k to win $400, or a 20% ROI for that particular bet. Are the Jets going to win by exactly 3 more than 1 in 5 times? What if the bets were +300 and +100.

If you are getting paid 20-1 on a 4-1 occurance you should take it no matter what provided you are not crippiling your bankroll. There comes a point where all of these become +EV at one point. My theory or hint is, people aren't taking these nearly as often as they should.

Edit: the Jets example sucks I edited the numbers. Like I said I am bad at explaning things outloud and threw this example quickly. Sorry.
