Tom expressed my point well, and I think he is right. If you feel the most confident about one game, you should bet as much of your bankroll as possible on that one game. If you had an infinite bankroll, then it would make sense to lay as much as you could on several games that you felt were +EV(without betting so much that you actually begin to affect the lines). However, if you have a finite bankroll, then you should pick the game you think is most +EV and bet as much as you are comfortable betting. Anything more is undisciplined IMO.

I'm thinking of an anolgy to poker. You can't just wait until you have aces in poker because there are blinds and antes. Given that you can choose when you bet in sports betting, why not just wait until you have the equivalent of aces and bet as much as possible?
