Showdown value is a hand’s chance of winning if the hand is checked down — a pair or ace-high that may already be best. Hands with showdown value usually prefer to check rather than turn themselves into bluffs.
Showdown value sorts hands into three groups on the river. Strong hands bet for value, because worse hands call. Hands with no showdown value — missed draws, king-high that cannot win — are the natural bluffs, because checking wins nothing. In between sit the hands with showdown value: middle pair, weak top pair, ace-high that may be good. They are too weak to bet for value and too good to bluff with, so they check and take the showdown.
The mistake runs both ways. Bluffing with a hand that has showdown value throws away the times villain checks back a worse hand: a pair of nines that might win should check. And betting it ‘for value’ only gets called by better. Showdown value also shapes earlier streets: a medium hand in position checks back the turn and calls a fair river bet, and when a float picks up second pair instead of a draw, it switches from attacking to pot control.

FAQ
What does showdown value mean?
It means the hand can win the pot without betting, because it may already be the best hand at showdown. A pair of nines on a board villain may have missed has showdown value; a busted flush draw does not.
Should you bluff with showdown value?
Usually not. Turning a hand that can win at showdown into a bluff risks a bet to fold out hands you might already beat. Bluff with hands that have no showdown value instead.
