Ep.9-1 The captain's vision

Here I will show you what Fukuji Mihoko, "the captain" of Kazekoshi Girls' High School, sees with her beautiful odd blue eye.




Kataoka 'Tacos' Yuuki aims to come from behind by making full flush, a killer hand, composed of one suit only.

Dora indicater is 6 circles: it means that dora is 7 circles.

She dares to discard two of her dora, 7 circles in this hand, a tile which makes the score one more fan up.

Inoue Jun, top runner of this game, of course notices Yuuki's hand because she has placed a precious dora on her bank in front of her.
Then Jun calls riichi, declaring "my hand is ready to go out" to intimidate Yuuki, who plans to discard her another dora.

Judging from the river of Jun, 7 pinzu (7p, 7 circles or 7 dots) may her claiming tile.
I would like to talk more and more with this hand...maybe in another column.


If the player obtains a winning tile within the first turn of calling riichi, another bonus named 'ippatsu' will be added, one fan.

Imazine discarding a dora for the riichi-declaring player immediately.
If the tile reveals to be "bingo!" the score, at least 1 fan riichi hand, will be multplied 1 fan for dora and another 1 fan for ippatsu.
Minimum payment is 5200 for non dealer.



Amazingly Mihoko discards her dora gracefully with confidence, so as to prompt Yuuki to go ahead, clearing her dora, too.

Why could Mihoko put her dora on her own river?





Note: there are four of a kind in each tile; no fifth 6p exists, for example.



Waiting set for claiming 7p may be classified into five cases:



a Waiting either 4p or 7p: Open-Ended (ryannmen)

b Waiting 7p to compose 789 (penchan)

c Waiting 7p to compose 678 (kanchan)

d Waiting 7p or another to compose a triplet (shanpon)

e Waiting 7p to make a pair (tanki)

Then gather information from the river, dora indicater (6p, in this case) and my own hand.

Note:dora indicator indicates the real doras which are NEXT to dora indicator.

The dora is 7p because the dora indicator is 6p.



(i) Jun declares riichi with discarding 8p.

(ii) There are two 6ps on the river.

(iii) I have one 6p(iii-1), two 7ps(iii-2) and three 8ps(iii-3)

(iv) Yuuki discarded one 7p

and

(v) The dora indicater is 6p



...OK, let's deliberate each case listed above.



Case a : Waiting either 4p or 7p :Open-Ended (ryannmen)

(ii) There are two 6ps on the river.

(iii-1) I have one 6p

(v) The dora indicater is 6p

So all 6ps are found.
Deduction: Jun's hand doesn't wait either 4p or 7p: Open-Ended (ryannmen)



Case b : Waiting 7p to compose 789 (penchan)

Case c : Waiting 7p to compose 678 (kanchan)

(i) Jun declares riichi with discarding 8p.

(iii-3) I have three 8ps.

So all 8ps are found.
Deduction: Jun's hand doesn't wait 7p to compose 789 (penchan) or 678 (kanchan)



Case d : Waiting 7p or another to compose a triplet (shanpon)

(iii-2) I have two 7ps.

(iv) Yuuki discarded one 7p.

Deduction: Jun's hand doesn't wait 7p or another to compose a triplet (shanpon)



How about Case e : Waiting 7p to make a pair (tanki)?

Mihoko says "Judging from Yuuki's style of sorting tiles, her tiles are all characters except the leftest"

and "Remaining dora worries her...OK I will fix it up, so follow me!"

Speculation: it is Yuuki , not Jun, who has the fourth 7p.



You're beat? I'm beat. How about Mihoko? She makes such a conclusion within a few seconds.
Beautiful, warm and clever woman...another monster.
