Mahjong Meditations

Setting this up as a little place for me to dump my Mahjong meditations. Most of this stuff will be specific to the Tenhou format, as that's the format I play the most. Been having trouble keeping focus while playing lately, so I'm trying to figure out how I can keep concentrating during a game. 

Will post some probability / maths related stuff as well, and might post about some mahjong related CS projects I have in mind.

General Rules: 5 mins break / stretching before each game. Full Screen. No ALT+Tabbing out of the page. Review after each session, not after each game. Limit weekday sessions to 3 hanchan and weekend sessions to 2 sets of 3 hanchan.

Will add to these rules as I go.

Prior Observations: Not paying attention to opponent hands (!!) Lose focus whenever I have a big lead, lose focus whenever I pay into a big hand, autopilot usually kicks in after a renchan in East Round. Overeagerness to get into tenpai even if it means pushing dangerous tiles. Doubling down on a play after I get unlucky.
