Block bets: the small bet that controls the river

A block bet is a small bet (often 20–33% of the pot) made out of position, usually on the river, with a medium-strength hand. The goal is to set your own price: you’d happily see a showdown cheaply, but if you check, your opponent might bet big and force you into a tough decision.

Why block bet

You have a hand like second pair or weak top pair.
If you check, a good opponent can bet big and make you fold the best hand — or call and lose a lot.
A small bet often gets called by worse hands and makes it awkward for your opponent to raise as a bluff.

When it works best

Out of position on the river with showdown value. See showdown value.
Against passive opponents who rarely raise.
On boards where your hand is medium: good enough to win sometimes, not strong enough to call a big bet.

When not to block bet

Against aggressive players who raise small bets as bluffs.
With strong hands: bet bigger for value. See value betting.
With nothing: a tiny bluff rarely gets folds.

When someone block bets into you

At low stakes, small river bets are usually medium hands, sometimes weak value.
With strong hands, raise for value.
With medium hands, call.
Raising as a bluff can work against thinking players, but not against players who never fold a pair.

Common mistakes

Block betting strong hands and missing value.
Always block betting the same hand strength — observant players notice.
Folding to a raise every time: decide based on the player.
