Full explanation — Equity
Equity in poker represents your theoretical share of the pot, calculated as the percentage chance your hand has of winning against your opponent's likely range of hands at showdown. This figure is constantly changing as more community cards are dealt and as betting action narrows down opponents' possible holdings. Players use equity calculations, often aided by software or simulators, to inform their decisions on whether to bet, call, raise, or fold. For example, preflop, AA against KK has roughly 81% equity, meaning on average, it will win 81% of the time, reflecting its strong statistical advantage.
