An open limp in poker is when a player enters the pot by calling instead of raising. Being the first player to limp into the pot is generally a poor strategic decision and is considered a weak play.
Open Limp Poker Example:
Let’s say you’re playing a $2/$4 and are seated in the lojack position. You decide just to call $4 instead of raising. This is considered open limping, as you’re announcing that your hand isn’t strong enough to raise, but you don’t want to fold.
