What is a check-raise in poker and when to use it

A check-raise is when you check, an opponent bets, and then you raise in the same betting round. It’s completely legal in almost all poker games. It’s a strong move: it builds a big pot with your good hands and can win the pot right away with a draw.

Example

You’re in the big blind with 7♠ 7♦. The button raises and you call. The flop is K♣ 7♥ 2♦. You check, the button c-bets 1/3 of the pot, and you raise to about 3 times their bet. You flopped a set and the button often has a king.

When to check-raise

For value: with very strong hands, like sets, two pair or straights, against a player who c-bets a lot.
As a semi-bluff: with strong draws such as a flush draw plus overcards, so you can win now or hit later.
On boards that fit your range better than the preflop raiser’s, for example low connected boards when you defended the big blind.

When not to

Against players who rarely bet: just bet yourself.
In multiway pots with weak draws.
With medium hands like top pair, weak kicker: a check-raise mainly gets called by better hands.

How big?

About 3 times the bet on the flop is a common size. Bigger on wet boards to charge draws.

When someone check-raises you

A check-raise usually means strength, especially from players who rarely do it.
Fold weak top pairs and bluffs; continue with strong hands and good draws.
Use pot odds to decide whether to call with a draw.
