What Is a Limp-Reraise in Poker?

A limp-reraise is a preflop trap: you flat the big blind with a huge hand, wait for someone behind you to open, then come back over the top. The point is to hide a holding like A♠A♦ and build a bigger pot than an ordinary raise would have built. It only pays when the raise you are counting on actually arrives.

How it plays out

Three things have to happen in order, and you control exactly one of them. You limp, an opponent raises, and you re-raise — typically to four or five times their open, or all-in once your stack is short.

Say you are UTG in a live $1/$2 game holding A♠A♥. You limp for $2 hoping the aggressive player on the button makes it $15. Instead four players limp behind you, the big blind checks, and you are looking at J♦9♦7♣ six-handed with $12 in the pot, out of position and with no initiative. Your aces are still the best hand, but nothing like the 85% they hold heads-up.

When it is worth trying

The line needs a dependable raiser behind you. That is a read rather than a strategy, and it evaporates the moment the table behaves differently to how you predicted.

Table	What normally happens	Verdict
Aggressive opener directly on your left	They raise, you get your re-raise in	Occasionally profitable
Passive live game	Four limpers, nobody raises	Turns a monster into a multiway scramble
Online 6-max	Limps are so rare they mark you as weak	Never

Why it is rare now

Solvers do limp, but nearly always from the small blind, where the price is half a blind and only one opponent is left to act. That small blind limping range holds some very strong hands precisely so it can re-raise the big blind's attack, which is the one version of this play that survives serious study.

From every other seat the solver-built preflop charts are raise-or-fold. AA, KK and AKs earn more by raising, because worse hands call a raise far more often than the trap ever gets sprung.

Price the limp-reraise by how often somebody raises behind you, not by how good it feels on the occasions they do.

The cost is quiet, which is why the habit sticks. Every orbit the field limps behind you, you have converted the strongest hand in poker into a marginal multiway holding and surrendered the two or three big blinds a simple open would have collected. Trap when you know the raise is coming. Raise the rest of the time.
