Calls are not mandatory. When making a call for a discarded tile (chii, pon, open kan), your hand is considered open. As mentioned above, open hands cannot call riichi, are ineligible for certain [[yaku]], and receive -1 han for certain other yaku. | Calls are not mandatory.

For example, if the player to your left calls chii on the first turn, you cannot declare double riichi. | ||

In other words, you can only call chii from the left player's discards. Therefore, the tile turned sideways is always indicated on the left. Chii may be particularly subject to the rule of [[#Kuikae|kuikae]] - when calling a sequence, you cannot discard a tile that would have completed the same sequence. See below for details. | ||

Ron opens the ''group'' of tiles, but does not open the ''hand''. When competing a triplet via ron, the triplet is worth reduced [[fu]], and the triplet no longer counts as a "closed triplet" in regards to [[sanankou]] / [[suuankou]]. The hand itself is not opened, though, so yaku like [[iipeikou]] are unaffected (even if the winning tile completes the iipeikou, it still counts). | |||

Similarly, some yaku can only be scored with a closed hand. Certain yaku, like [[chiitoitsu]] and [[mentsumo]], are closed based on their structure or nature. Other yaku, like [[iipeikou]], the requirement of a closed hand is entirely artificial. Unlike instances of kuisagari, you cannot use these yaku to fulfill the yaku requirement of an open hand: these are not considered 0 han yaku. For [[ryanpeikou]] in particular, if it were affected by kuisagari, it would score 2 han when opened. But in actuality, you cannot achieve ryanpeikou at all with an open hand. | Similarly, some yaku can only be scored with a closed hand.

Before making a tile call, players should consider "is it worth opening the hand, or is it better to remain closed?" Naturally, there are advantages to both. For starters, players should know the [[yaku]] and their hand values. A closed hand can call riichi and is worth more; an open hand is faster. Players should consider their point standing, hand value, number of tile draws left, and other factors before opening. For more details, see [[naki strategy]]. | Before making a tile call, players should consider "is it worth opening the hand, or is it better to remain closed?"

[[Yakuman]] hands, assuming they can be won open, don't reduce in value after a call.
