Sorry to interupt but it's important to point out to a few posters that there's no such thing as "negative implied odds".

Implied odds are traditionally defined as your payoff if a line works out in a certain way that is beneficial to you divided by your incremental cost to pursue that line. The dividend, the divisor, and the quotient are all positive numbers.

Reverse implied odds are traditionally defined as your current max payoff (the pot) for lines which you do not anticipate improving divided by your anticipated additional cost to continue to showdown. The dividend, the divisor, and the quotient are all positive numbers.

Dividing cEV by incremental cost to enter/continue with the hand is expected reward/risk, and that ratio can be negative.
