Full explanation — Cold Call
A cold call refers to calling an open-raise when you haven't yet put any money into the pot during the current betting round. This play signifies a willingness to proceed without taking initiative, often indicating a medium-strength hand that plays well post-flop but isn't strong enough to 3-bet for value or as a bluff. Suitable cold-calling ranges typically include hands like small-to-medium pocket pairs for set-mining, suited connectors for their implied odds, or strong offsuit Broadway cards in late position. Cold calling should be done judiciously, as it gives up initiative and can lead to difficult spots out of position.
