How To Check-Raise In Poker

A Check-Raise Is Checking And Then Raising When Your Opponent Bets, And It Is One Of The Most Powerful Lines Available To The Player Out Of Position: Raising A One Third Pot Bet To 110 Into 100 Needs To Work 45.3% Of The Time As A Pure Bluff.

Why Check-Raise

The Player Out Of Position Acts First, Which Is A Disadvantage On Most Streets. The Check-Raise Turns It Into A Weapon. By Checking, You Let An Aggressive Opponent Bet With A Wide Range, Then Raise To Punish The Bluffs And Build A Big Pot With Your Strong Hands. It Is How An Out Of Position Player Fights Back Against An Opponent Who Bets Too Often.

A Check-Raising Range Needs Both Kinds Of Hands. Strong Made Hands, Such As Sets And Two Pair, Raise For Value. Draws With Good Equity, Such As Flush Draws And Open Ended Straight Draws, Raise As Semi Bluffs, Because They Can Win When The Opponent Folds And Still Improve When Called. A Range Made Only Of Strong Hands Is Easy To Fold Against; A Range Made Only Of Draws Is Easy To Call Against.

The Price Of A Check-Raise

Suppose The Pot Is 100, Your Opponent Bets 33 And You Raise To 110. You Are Risking 110 To Win The 133 Already In The Middle, So As A Pure Bluff The Raise Must Work 45.3% Of The Time. That Is A Lot More Than A Small Bet Needs, Which Is Why Check-Raise Bluffs Work Best With Hands That Have Backup Equity When Called.

The Size Of The Raise Is A Choice. Larger Raises Need More Folds As Bluffs But Charge Draws More And Build Bigger Pots For Your Value Hands. Smaller Raises Risk Less But Give The Bettor A Better Price To Continue. Whatever Size You Choose, Use It For Your Value Hands And Your Semi Bluffs Alike.

When To Do It

Check-Raise More Against Opponents Who Continuation Bet Too Often, And On Boards That Hit The Checking Player's Range Well, Such As Low, Connected Boards That A Big Blind Defending Range Contains More Of Than A Preflop Raiser's Range Does. Check-Raise Bluff Less Against Opponents Who Rarely Bet Without A Strong Hand, Since Your Bluffs Will Run Into Hands That Do Not Fold.

Think About What Happens Next. After A Check-Raise Is Called, The Pot Is Large And The Stack To Pot Ratio Is Low, So Plan Which Turn Cards You Will Keep Betting And Which You Will Check. A Check-Raise With No Plan For The Turn Often Loses More Than It Wins.
