strategy question

strategy question I recall a strategy of correlating the 1H team with the 1H total. involved taking either fav or dog with the over or under based on the line being 1/2 or more of the 1H total....can anyone please steer me straight? TIA.
The example you give is a highly correlated parlay but finding a book that would let you make the bet will be very tough. Most know better and block anything where the spread is 30% or more vs the total. Look for a lower spread to total ratio and concentrate on getting all the key side and total numbers on your side. Those you can get in and still have value.
