Once a hand reaches 4 han, every han afterwards is reduced in value. So if a hand has 4+ guaranteed han after opening, it's often best to call. At this point, the extra speed from calling is often worth the drop from value.

When a hand is cheap, the opposite effect can occur. If a hand would be 1 han (riichi-only) when closed, or 1 han when opened, going open is often better. This mostly happens with [[yakuhai]] pairs - keeping the pair ruins [[tanyao]] and [[pinfu]], but pon gives 1 han through the yakuhai triplet. Even when considering the score bonuses from riichi (ippatsu, uradora, [[mentsumo]]), an open hand's increased speed is often better than the chance for extra points.
Also consider calling with 2 [[dora]], since the value of a 3 han hand is still good, and it is often not difficult to get another dora.
 
===Lack of value===
When a hand is cheap, the opposite effect can occur. If a hand would be cheap when closed, but still have a yaku while open, then calling may be the best choice.
 
This most often happens with [[yakuhai]] pairs. Keeping the pair ruins [[tanyao]] and [[pinfu]], often resulting in a riichi-only hand, while a yakuhai pon gives 1 han. There isn't much difference between 1 han closed (riichi-only) and 1 han open. Even when considering the score bonuses from riichi (ippatsu, uradora, [[menzen tsumo]]), an open hand's increased speed is often better than the chance for extra points.


===Point standings===
===Point standings===
As with most things in riichi mahjong, the game's specific point standings will alter the need to call. If 12k points are needed to escape 4th in all last, it is best to stay closed even with a 4 guaranteed han hand. If you need 1k points in all last, call as soon as a yaku is available.

==When it's late in the game==
==Call when late into a hand==
The earlier in the game it is, the more time there is to chase a valuable closed hand. Conversely, when it is the mid- or late- game (generally turn 8+), consider making a call if it would cause you to enter tenpai without too much loss in value.
