Level 4 - Amatuer
Amatuers start to appreciate the mahjong game better and truly find it a fun and engaging game that is multidimensional. An amatuer starts to read the mahjong game better and is able to adjust his strategies depending on situation. Amatuers are slowly becoming experts in mahjong but ironically, it become easier for experts to predict their games as they become better.

Knowledge: An amatuer's knowledge of Mahjong would have gone beyond the rules and probability, into the realms of game theories. They appreciate that Mahjong is not an individual game but a game with group dynamics and starts to develop their knowledge in the group game.

Skill: An amatuer is able to read the game based on the tiles that appeared on table. He is able to tell if other players are going for "qing yi se" or "ping hu" when it is less obvious because he has the skill to read the game in general. He knows if this game is going to be a chance for him to strike it big or if this game is one where he needs to be on the defensive stance.

Playing Style: Flexi-logic. No one fixed playing style will win you every game and an amatuer will choose a style he finds most suited for him based on his logical deduction from reading the game.

Self assessment: You find your mahjong skills lacking, especially you feel lost in how to best react to things that you observe. You might be guessing other players intentions and get the "ah ha... I thought so" feeling every now and then

Reaching this level: One needs some form of enlightenment to reach this level. Either you are gifted and develop this aspect of the game yourself, or you have to study how experts play. Or better yet, listen to expert advice and think hard. You need to be observant and have plenty of practice too because you need to do more things at the same time now.
