Quick Question

Quick Question Since it is slow if someone would be willing to take a minute to educate me, I would appreciate it....... Earlier last week I took Ohio -7.5 for $220. By Saturday AM Ohio at one of my outs was up to -10.0. What is the correct move in terms of buying back or middling, the amount and the logic behind the move? Thanks in advance for your consideration.

my opinion: don't try to middle or buyback unless you wagered too much of your bankroll on it. 8 and 9 are not key numbers which would make any attempt at a middle unprofitable.

Here are some reasons to buy back on other side 1)If you have too much of your bankroll at risk on one side and need to get some off on the other side 2) You were just taking a position early because you knew the number would move 3) the line has moved enough that the other side you are looking to buy back on is also now a postive EV bet in your opinion. 4) weather and or injuries has changed your opinion on the game
