I understand the temptation, but should only do it if you think Milw +7.5 is +EV on its own. Personally I am type to sit on massive +EV postion without giving money back.
I agree.
That said, I have developed some strategies where I seperate the bankroll and take more of an EV position with the intent to sell back on another +EV position (independant of the first as information has changed with the game starting).
It's an extra, "steady", strategy that still deals with +EV.
But in general since EV can be hard to come by, when you get it, don't give it back.
There will be more games, with more EV, as the rotation continues day after day.
