Suji and EV - Riichi Mahjong Strategy

[@boboyqc]

I was looking for good strategy videos on mahjong for such a long time! This is great! Thank you!

[@jdotaing]

Thanks for uploading again. Welcome back!

[@eikofee]

I really appreciated the part on the EV Calculation, thank you very much for these explanations !

[@adamsolino7803]

Fascinating!. I love these videos. Please don't stop making them.

[@Crow77]

No plans to! I'm targeting 2 things a month, whether they're full strategy like this, paifu, or something else, but I think just getting in a groove for uploads will help me out too.

@@Crow77 Bro, awesome. Can't wait!

[@nekkowe]

Ah, what a nice surprise! Thank you for the pointers!

"Basic strategy" playlist "You just need to memorize every Suji pair, so that you recognize them at a glance and don't lose time trying to remember which tile corresponds to the one being discarded as its Suji, count them, count all the other discarded tiles from the same suit, calculate the point value of your own hand, instinctively know what sort of hand your opponent might have and calculate its value, then refer to the table of values you've memorized beforehand and based on the percentage statistics decide whether risking throwing a potentially dangerous tile is worth the Yaku you are trying to build. Then repeat the process for every suit and potentially every player - all within 25 seconds" ... Our definitions of "basic" are vastly different xD

Damn I have to admit the last thing I expected today was a new Crow video

[@Crow77]

Me too 👀

EV is so hard to calculate in a 5 second/move game... I can't believe all this stuff is just basic level

[@Crow77]

This is one of the videos that is harder to classify. The true EV calculation, to the point of getting exact numbers, is mostly trivial, to the point it can be boiled down to a table. From there, you can remember breakpoints - if you cound 10 dead suji, that's where your 2500 point swing becomes 0, for example. And based on the math, it is rarely OK to push for ryuukyoku against 2 other players. At the end of the day, it is all pretty general anyway. A lot of this is to point out that sometimes, it is worth it to hold tenpai at the end. As a general rule of thumb, if you think only 1 other person is tenpai at the last discard, pushing a single musuji is fine.

if it helps at all, you can climb VERY high in mahjong without ever doing an EV calculation. it's not something i'd say is necessary to get better. more of a "nice to know" thing if you really want to nerd out (which is totally valid) :)

Since the riichi player has 1 sou in their discard, why 1-4 sou is still live? Moreover, are those tables with red 5s? If so, how do they change without them?

[@mikel6966]

this was a great watch when im trying to get better :)

[@opposite342]

7:20 here you showed 3-6p as dead here but i think you meant 1-4s since only the 9p had been thrown, so a 45p block waiting for 3-6p is still possible Edited: nvm I just saw the called tile. But then it should be 7 dead tiles with 1-4s as well no?

[@sakesaurus]

dude awesome video

[@LeMrAlpaca]

Appreciate the guides

[@AirinTV]

Amazing video as always, Crow! Tell us, did the 4p deal in at the end, or no? :eyes:

[@Crow77]

It did not! This is one where I really questioned it as I was making the play, and based on the math, it makes sense that it was really close. But, I think I beat the odds in this situation - as I said in the video, definitely don't think it's worth it on ladder.

[@5zlotychkun]

5:30 technically 1 sou could also be used in a kokushi wait, but it's understandable why you skipped that shape :D
