Re: Do you riichi?

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...

Re: Do you riichi?

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...

Re: Do you riichi?

Sanshoku which is normally rare is even harder with the character tile suit distribution Do you mean the tiles visible on the whole board? One reason to hold on to and then discard 2 is because you have 24, and then you draw a 5, and your wait changes from 3 only to 3/6. If you instead call and the...

Re: Do you riichi?

It's possible toimen needs 3m, but their hand isn't likely expensive and they aren't the dealer and there aren't any warning signs like them discarding 4m or 5m from their hand last discard either Why do you think their hand isn't expensive? If the 2p was discarded after a call, then 6p isn't so da...

Re: Tenhou progress thread

I'm trying to reach 3rd dan; I had a coupla bad streaks that set me behind, but overall I think I'm on the right track. This is my last month:

Now I just need to get less fourth places (hoping to deal less when riichied and to opponents in dama in sixth turn :mrgreen: ).

Re: Do you riichi?

Not so much a do you riichi, rather a do you push: 20160210.jpg I'm first with with a small lead; I could discard 137m, with 37m that could be dangerous. Kamicha could be tenpai, possibly with a small hand (barring dora; I don't give him honitsu), but if I pay my lead decreases. South 2, so still so...

Re: Do you riichi?

What would other people do here? 1st is close, 3rd and 4th are kind of far back. With riichi, the hand is pretty valuable, or, I could discard 9m and go for tanyao, but my hand would be full of dangerous tiles, and I likely have to discard 7m for a good tenpai. For this reason, discarding 7m now co...

Uhm... I think I'd ron hoping in uradora, rather than hoping to tsumo one out of at beast three tiles. Do you think the chances for tsumo are better than those for uradora?

Do you meld?

After the acclaimed Do you Riichi?, here there is its sequel: Do you meld? :mrgreen: When to meld is something I'm trying to learn, and in my last game there was a situation I thought about posting it here: 20160206.jpg It's very early in the game: I don't have a great hand (3-shanten after melding,...

Re: Do you riichi?

Yeah, Riichi was a good play but with Tsumo you'd have 2000/3900 With riichi tsumo yes, but with only tsumo it'd have been 1000/2000, wouldn't it? Sanshoku and tsumo, it'd be 30 (20 + tsumo + penchan wait) fu 3 han O_o Am I missing something? Edit: If you mean that I would with riichi tsumo I'd be ...

Re: Do you riichi?

I don't think our decisions should be judged on the basis of seeing opponents' hands Sure, you're right: it's the reason I hide my opponents' hands while posting screenshot, so people replying can't be influenced by them. That was just a side comment :D I think riiching was right also without knowi...

Re: Do you riichi?

I won by ron a round later (shimocha 11th discard), so each of them just discarded one tile, but for both was genbutsu. Here's the whole game, if you're interested: http://tenhou.net/0/?log=2016020522gm-008f-0000-447015ee&tw=0 (I riichied also because 7-crak was suji; it was a good thing, since all ...

Re: Analysis: Mauro's Games - 05

I hope you don't mind me jumping in here Not at all, thanks :D East 1: I would discard the 3-dot and then 1-dot , but this is very minor To have a safer tile to discard later? East 2/1: I think I kept 8 thinking about chiitoitsu (if I get tenpai, waiting on 8 is better than waiting on 7), and disca...

Re: Do you riichi?

Couple of cases in my last game: 20160205 (12a).jpg South 3, I'm second with a nice lead on third (6000: not so good, at least mangan would be better, but neither so bad) and not so behind first (4900); I can riichi, but discarding 2-crak or 5-crak, which are not safe against shimocha. The wait isn'...

Re: Analysis: Mauro's Games - 05

By the way, I was wondering: do you find suji (beside the usual omote) so useful? I rember to have read on Just Another Japanese Mahjong Blog that - according to the author - at least some of them are proven wrong, and don't really affect the risk of the tiles, so he doesn't even explain them.
