First, got to find a book that does Even/Odd bets for the NBA each quarter.
Simple Martingale system for every game.
Each NBA Game first quarter bet total score will be Even for one unit.
Every winner you stop for that game.
Second Quarter two units on Even. Again stop on all games after you win. Continue on to the 3rd quarter only on games you lose.
For the life of me, I can not remember the last game where all four quarters had an odd total.
