Preflop equity
KK vs A5s
All in before the flop, KK (pocket kings) wins 66.6% of the pot against A5s (ace-five suited), which takes the other 33.4%. A clear favourite, but far from a lock: A5s gets there roughly one time in 3.
Equity counts ties as half. Figures are from 200,000 simulated deals per matchup, accurate to about a tenth of a percent, with card removal applied; the calculator below enumerates every runout exactly for specific suits.
