Measure weighted Hold'em hand categories and blocker-aware current nuts against every legal opponent hand. Free to use, with no account or download.
Enable JavaScript to calculate. The calculation runs in your browser.
Enter your range, including weights such as AA:50% or AKs@0.25; use random for every starting hand. This is exact on the current board. Nuts means no legal two-card opponent hand can beat you now, after hero/board/dead blockers. On the flop or turn it does not mean the hand remains best on later cards. Ties are included in nuts; exclusive nuts cannot be tied or beaten.
