The rules for a show in 3 patti are as follows:
All except two players must drop out before a show can occur.
Only a blind player can call for the show. A seen player can either continue betting or fold.
The player calling for the show must pay an amount equal to the current stake.
If both players are seen, any player can pay an amount twice the current stake to call for a show.
In a show, both players compare their cards and the higher-ranking hand wins. If both hands are equal in rank, the player who didn’t call for the show wins the pot.
