Poker strategy: Stay for two more cards…
… if the first three cards have the same suit or form a sequence. If you get a fourth that fits the suit or sequence, keep going. Otherwise, fold after the fifth card.
Poker strategy: Watch the betting action.
A pair in the hole (also called a wired pair) is a promising hand, but not if the pair is probably beaten by cards visible on the table. The betting action may guide the decision to call or fold.
