Playability
Playability is how easy it is to play a hand after the flop, and how often it can make strong hands or good draws. Hands with good playability, such as suited connectors, are valuable.
The simple explanation
Some hands are easy to play after the flop, because they make clear pairs, draws or straights. Other hands, such as ace-small offsuit, do not do well. Playability is about whether your hand can continue on many flops.
A closer look
Playability depends on connectedness, suitedness and the ability to make strong hands. Suited connectors and suited aces have good playability, while hands such as king-nine offsuit are often dominated and are difficult to play. It also depends on position and stack depth: in position and with deep stacks, playability is higher. When you choose preflop hands, think about both the raw strength and the playability.
A practical example
Seven-six of hearts has good playability: it can make flushes and straights. Ace-four offsuit has poor playability, because it is often dominated.
