Consecutive cards of the same suit in your hand. Example 7-8 of hearts are suited connectors. These can be powerful hands when played properly but also can be troublesome to play. Chippy says leave these to the experienced player to play.
Suited connectors is a poker term referring to pocket cards which are of the same suit and consecutive in rank. Example: A♠ 2♠, Q♥ J♥, 5♦ 4♦. In Texas hold'em, suited connectors play well against multiple players when they can see the flop cheaply.
