A discussion about combo bets

[VisionAlex]

If you bet a combo ,composed from two matches , it's a bad ideea because the juice from every bet multiplies giving a bigger edge to the bookie.

But what if you have the edge on the bets. Let's say u think u have 4% edge by betting each event. Wouldn't a combo increase your advantage as the edge multiplies. It also increases the variance but it's a good trade to stay under the bookies radar. Can someone help with the math here ?

Yes, your overall edge will increase when parlaying 2 +EV lines. Trade off will be higher variance. Parlays can also be great way of getting more down on a good line by circumventing limits.

If you use the Kelly Calculator, it recommends playing a tiny percentage of BR on the parlay as well as a much larger percentage on straight bets.
