Ranges and blockers
Select several Holdem starting hand classes and see which physical combinations remain after known cards are removed. This is a teaching model with equal combo weights, not playing advice.

The 13×13 grid applies only to Holdem. On a narrow screen, scroll inside the grid; the text field is an alternative.
The groups below are mathematical sets, not strategy advice.
Known cards
Cards removed from the deck. They are not player positions or a prediction of strategy. Select zero to seven cards.
Select an available card
Physical combinations
AA has 6 combos; a known ace of spades leaves 3. AKs and AKo together have 16; after the ace of spades and king of hearts, 9 remain. A full range after seven known cards has 990 of 990 possible combos.
The 169 cells are not equally likely: a pair has 6 combos, a suited class 4, an offsuit class 12.
