2. It has been stated that one cannot "pung" unless it makes up three or four of a kind. This is true with one exception. In the case: when a tile will complete a player's hand allowing him to "Mah-Jongg," the tile may be punged. Example: A player with four sets and an odd tile may pung a tile which matches his odd one. The rule is that "a player may at any time 'Pung' a discard which will complete his hand and allow him to Mah-Jongg."
3. The denomination and suit of each tile must be announced as it is discarded, a player discarding a 3 of character, announcing 3 character, to prevent confusion of a player who may be studying his hand. This is more of a courtesy of the game, than a rule.
4. A "Pung" has precedence over a "Chow" and if one player can pung the same discard that another player can chow, the former has the right to appropriate the tile.
5. If a player can pung a discard which will complete his hand and another player can pung the same discard to complete a set, the former has the right to take the discard.
6. If two players pung the same tile to complete their hands, the precedence is given to the player claiming the tile nearest to the discarder in a counter-clockwise direction around the table.
FOUR OF A KIND:
Before speaking of "four of a kind," it is better to give the reason for exposing a set made up of a pair and a punged discard, and make clear at the same time, what is to be done when three of a kind are completed by draw.
