Chombo: Difference between revisions

'''Chombo''' {{kana|冲合}} is a penalty for heavy rule violations.  Some moves may be considered [[dead hand|minor and correctable]], like accidentally drawing the wrong tile from the wall.  Rule violations subject to chombo are harsh enough to abort the hand and impose a point loss on the offender.

A player penalized with chombo must pay a specified point penalty, depending on the setting.  The most common is a [[mangan|mangan-sized]] penalty. To each other player, the offender must pay what the offender would have received on a mangan tsumo without [[honba]]. In other words, the offender pays a "reverse mangan tsumo".  An offending dealer must pay 4,000 to everyone, and offending non-dealers must pay 2,000 to each non-dealer and 4,000 to the dealer.  Other methods of handling chombo point penalties may be incurred after the game.  In some instances, the points specified may directly affect the [[uma]], or the +/- end scores.  Casual settings may simply ignore and bypass chombo altogether.

In all instances of chombo, the current hand is then aborted and repeated. Players who have declared [[riichi]] during the aborted hand get their riichi bet back. Most rules leave the [[honba]] count unchanged for the repeat, while some rules may handle this like any other [[abortive draw]].

Cheating is very possible in the game.  There are known various and elaborate cheating tricks.  Among these include stealing from the discard pile, or tile trading from the hand to the wall. For example, some tricks involve the ''sleight of hand''.

Tournament judges might decide on an even more severe punishment than chombo or disqualify the cheater.

Players cannot declare a win with an incomplete hand or on an incorrect waiting tile.  The following conditions are deemed as invalid win:

* Declaring a win with an incomplete hand.

Riichi may only be declared with a [[tenpai]] hand. Declaring riichi with a noten hand is not detected by the other players immediately. It goes unpunished if another player wins the hand or on an [[abortive draw]]. The noten riichi is punished with chombo if the player declares a win, or when the hand must be revealed at [[ryuukyoku]].

If the hand ends in [[ryuukyoku]], riichi declarers must show their hands as proof of being in tenpai. Depending on the specific rules, a player may refuse to show the hand and instead take the penalty, even when tenpai.

{{main|Kan#Kan during riichi}}

A player with a dead hand is forbidden to make any type of call, such as chii, pon, kan, riichi, tsumo, or ron.

A player may not crash and destroy the wall, such that the tile arrangement cannot be recovered.
