Yaku are a series of hand combinations and situations (like riichi itself); you can find the list according to EMA rules at the end of this manual: https://www.ermc2019.com/wp-content/uploads/2017/08/Riichi-rules-2016-EN.pdf. Your hand would have a yaku if you declared riichi, or if you had another ...

Legendary Gambler Tetsuya. And no, no sunglasses XD

In a show I'm watching, one of the players has this discards: Hand.jpg From this the other players suppose that he's tenpai, and that his outs are 3-dot 6-dot. Assuming he has tenpai could depend on him discarding 9-dot 8-dot, since that's a tātsu, so either he drew better tiles, he's aiming for tan...

Would it make sense to discard ? You could have two red dora, tanyao, maybe closed sanshoku.

Under EMA rules, you simply use the most valuable hand:

All players at the table are responsible for ensuring that each winning hand is scored correctly and to the maximum points

Same as or2az: 6 crak or white dragon; maybe 6 crak, since it's a middle tile and it's near dora, so later on could be a dangerous discard, and white dragon could lead to little three dragons; but if you had to pon red dragon I think would be quite unlikely to have it. Still, as discard later on I t...

Good point about E3-1. I'm wondering if 4s wouldn't be the best discard there It depends if you want defend: I'd discard South and go from there. E2-0 By safe tile you mean 6m? I thought winning that hand was highly unlikely so I favored dama there But going dama you lose the chance to ron on 7p, w...

I don't play open tanyao, so keep in mind my comments could be off: About the first game: East 2/0: You could riichi discarding a safe tile and waiting on 7p 1z; that hand is at least mangan, so maybe I'd have taken the risk. East 3/1: When you discard 7m, I think I'd have discarded 2p: 2p is a lone...

One game I dropped from first to last because I paid three consecutive hands: two of them I was in riichi, the third was dama in fourth round (total: 18k). Another game, I never got tenpai. I'm sure I'm still making mistakes, but these last games luck isn't on my side

Sure:
I'm currently again in a negative streak, way below my usual results; I'm trying to understand if I'm getting something really wrong, and meanwhile maybe I can improve my reading of the board.

Thinking about it, I should have at least three safe tiles: I see all of 9m and of 8m (and even three 6m); that means my three 9m are safe.

This is something I'm thinking about: when to push and when to fold. I had a rather terrible game in which I ended up fourth, and while some of the hands I paid were kinda unavoidable some I'm not sure I played at best other hands; one was this: 20160214.jpg South 3, I'm third by 1700; toimen and ka...

Would you go in defense if after kamicha riichied you should discard dangerous tiles?

Not sure what's hanetsumo

Both can improve to 1345 on one end, but 134 can improve to 1234 which is like a lone 4 but better, and 145 can improve to 1456, which is just a lone 1 Yup, but since 1234 is quite flexible as a form, I think I'd keep the 1 in 134, rather than that in 145. Another situation: 20160213.jpg South 4, I...

According to Daina's book, if it's a pon don't bother asking yourself if the tiles near the discard are safe or dangerous; if it's a chii and the discard is in the same suit, it's likely safe; if it's a chii and the discard is in another suit, it's likely dangerous (which, pon aside, agrees with wha...
