In Japanese mahjong, | In Japanese mahjong, a player's final placement (1st/2nd/etc.) is often important. Due to the [[oka and uma]] systems, there are huge bonuses or penalties for changing place. In competitive environments, placement can be important for gaining rating points. Therefore, players should act differently as the overall point conditions change. For example, when given the exact same hand, a player with a huge lead might not want to [[riichi]], but a player far behind may be desperate to riichi. Therefore, it is not only important to look at the hand, but each players' current points as well. | ||

Say | Say a Saint 1 plays in Majsoul. When in 3rd place, and an action has a 50% chance to net 2nd, but a 50% chance to net 4th, it has terrible value. If successful, it nets only +65 points, but a failure results in a significant -255 points. Even with a 50% chance for 1st, and a 25% chance for 4th, it is still a net negative. | ||

If higher ranked, do what is possible to avoid being last - try not to take risks late in the game, even if there is no immediate threat of being 4th. At lower levels, it is best to improve on ''average placement'' (including fundamentals like [[tile efficiency]] and [[defense]]) rather than focus on avoiding 4th specifically. | ||
The reason the 4th-place penalties is so high to punish players for leaving early. When playing with physical tiles, the point distribution is more even (they tend to favor 1st place, due to the [[oka]] system). Of course, no matter where you play: if you are currently in 4th place, you should obviously do what you can to escape. | |||
