2.2Terms related to the whole hand

Tenpai
A player's hand is tenpai if it fulfils all these conditions:
1) The 13 tiles' hand needs only one more tile to form a complete hand of four groups and a pair, or seven different pairs, or the Thirteen Orphans yaku.
2) The completing tile must exist. A hand needing five identical tiles can never be completed, so it is not tenpai.
3) The player is not under a "dead hand" penalty.
The completing tiles may be depleted.
During the player's turn, the 14 tiles' hand is tenpai if it will fulfil the above conditions after discarding.

Noten
A hand is noten if it is not tenpai.

Winning hand

If the hand is completed by calling a tile (ron), the last group or pair is melded but the hand is still closed.

Open

I.e. a hand is open if it has at least one melded group before the winning tile.
