Math Guys --- Is this good or bad EV ?

have a -300 tennis fav in a suspended match , will resume july 9.

sets are even 1-1 , 3rd and final set to be determined

if i forfeited 50% of wager now before the conclusion would this be a +EV ?

You would need to know the ML at the start of the 3rd set. If it's still -300, then forfeiting a portion of your wager wouldn't change your EV.

I'd look at it like this. The real odds of winning the bet have definitely gone out of you favor but the question is how much. Let's say the real odds at this point of winning are more like -200 instead of -300.

So that means you're risking 300 to win 100. But let's say it's only a 66% chance you win and 33% chance you lose.

66% * +100 = 66

33% * -300 = -100
-------------------
So if you keep the bet, your EV is -34

If you surrender half the bet, it's a 100% chance of losing $150.

So I'd hold on and not surrender.

check the rules closely wherever you bet it, tennis rules vary a lot.

what makes someone a 'math guy'?


someone who understands standard deviation and can apply it to sports lines using math formula. Either that or someone who has access to one of many thousands of arb calculators found all over the net.
