Hey everyone this is my first post here at sbr so my apologises if this post is in the wrong place or if the information has already been covered.
I had a spot today where I was betting nba Washington vs golden state. Bet golden state at -8.5 points at $1.92 before the start of the game. At half time golden state were up by 18 points and the new line was Washington + 18.5 points at $1.92. Is this a clear stop to go ahead and buy Washington at the +18.5? Considering that if golden state with between 9 and 18 points I win both bet or any other result I essentially break even minus the vig. On a side I figured it was a clear middle because of the big spread of points to clear both bets (9-18 points).
What factors should be considered when choosing to or not to middle?
Thanks guys all feedback is welcome.
