Reverse Implied Odds

Also known as: reverse implied odds, RIO

The extra chips you expect to lose on later streets when you make a second-best hand — the penalty that makes dominated draws and weak made hands costly.

Reverse implied odds (RIO) are the dark twin of implied odds: the future money you bleed when you improve to a hand that's still beaten, or call down with a marginal holding that's good only when behind. RIO doesn't appear in the immediate pot odds calculation, so naive equity math overrates these hands.

The hands most exposed to RIO are dominated draws (a low flush draw, the idiot end of a straight), weak top pairs out of position, and offsuit kicker problems. High SPR amplifies RIO because more money can go in on later streets when you're crushed; deep, out-of-position, and against a range advantage are the worst conditions. Practically, RIO means you should discount the equity of hands that win small and lose big, fold them more often versus strength, and favour position and absolute nut potential. Against a nit who only barrels with the goods, RIO is severe; against a calling station it's smaller because they pay your value too.
