Situational analysis: Difference between revisions

Latest revision as of 19:37, 14 September 2024

When performing situational analysis, a player accounts for the game round and each player's current score to determine their decisions.

A player's final placement (1st/2nd/etc.) is often important, as the oka and uma systems tend to give huge bonuses/penalties for changing place. In online websites like tenhou.net and Riichi City, your placement is the only thing that matters for rank 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.

Hand values

Main articles: Scoring table and Gyakuten

In order to perform situational analysis, players should know the potential hand values (or at least, the common hand values). Knowing the score table is important when determining when to riichi and when to open the hand. For instance, if it is the last round, there is no need to riichi when 2000 points behind 1st place with a 2 han hand.

Relative goals

Especially in the last hand, players may need to address the different goals of the other players. Players in last generally have a win-at-all-cost mentality. Players in second/third may seek to improvement their placement. Point leaders may simply want the game to end and/or protect their position. The point differences between players indicate any sort of possibility for these scenarios.

Fourth Place Avoidance

In the online clients tenhou.net and Majsoul (before Celestial rank), there is a huge penalty for 4th place for players of a high rank.

Tenhou.net: If a 6-dan player plays, they get 75/30/0/-120 points for placing 1st through 4th, respectively.
Majsoul: If a Saint 1 player plays in Jade Room, they get 125/60/-5/-255 rank points for placing 1st through 4th, respectively (counting uma).

Say a Saint 1 plays in Majsoul. When in an otherwise guaranteed 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 just a net neutral.

It is important to restate that huge 4th place penalties only apply to high ranked players. 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 do what is possible to escape.

-'''Situational analysis''' takes into account important game conditions, mainly the [[Ba|game round]] and the current scores.  This prompts players to a state of awareness regarding their hands and actions necessary to attain particular goals regarding placement.  Likewise, players take into account the goals of the other players.  Analysis is particularly required during the last hand of the game or even in the [[Enchousen|extra wind round]].

Given a [[haipai|starting hand]], a player may receive a good picture on the viability of attaining a hand of particular value.
