quick decision vs WWYD

[Ignatius]

Don't worry, I don't even understand myself. I'm unable to explain myself like you do because of that.

As this topic is about quick thinking, I did only that. Even if it's not rational, I'll stick to my decision.

When the thing is like a WWYD question I try to analyze things the best way I can. But I tend to be more or less like this, kinda irrational, I think. I'm not too good analyzing either way. So I usually end picking my own choice and reading the analysis people better than me does.

In the end, when playing mahjong I try to remember what I've read and try to apply it, but most of the time I play by sheer instinct.
As I have not enough players to play it with my table and tiles, I really didn't need to memorize the scoring tables, because I play with videogames or online programs, which calculate for me the points. I'm always thinking because that maybe my game doesn't develop as good as other players. But I don't know if it's true...

Edit:
You know what? I don´t care. I only need to have fun playing this game. Better to be positive!

Here's the situation. It's South 2 with 13 tiles remaining and there's 2000 pts separating 1st from 2nd. I already have tanyao dora 2 and have just drawn the . Do I riichi and what do I discard? Obviously, it's one of the bams, 3, 4, 5, or 6. Let's pretend the clock is ticking and I have to think fast.
I decide to riichi (mistake?) and toss the . (I might have tossed the instead but I saw the in my discards and quickly realized I would be furiten). Time's up. I managed to beat the clock.

Okay, now let's rewind and eliminate the clock. Quick decision over, now it's a WWYD. What would you have done?
note: I did win the hand but don't let that influence you.

sidenote: I think I noticed that in Tenhou, when you riichi, and don't choose a discard before time runs out, that it chooses one for you. Does it just pick one of the possible discards at random?

It is South 4, probably the last hand of the match, and there are 100 points separating 1st place (the dealer) from 2nd place (me). I have a mangan on the horizon with the green dragons, but I really only need to win the hand. I'm waiting on the (none out yet) , with 18 tiles remaining.

But then, West discards the and the clock starts ticking (hypothetically). Need time to think. Do I pon it and discard what, the 4, 5, or 6 bam?
I decide to pon the 9 if only to make East lose a turn, and maybe get a better wait. What's better, 46 shanpon, 47 ryanmen, or 36 ryanmen.
A quick look at the discards and I toss the 6, deciding on the 47 ryanmen wait. Time has just ran out. (It actually ran out a while ago).

Now to go back and re-analyze the situation. What would you have done?
(p.s. I did win the hand)

January 8: That was the right wait, good job on recognizing the souzu shape. But not riiching would have been better. You're first, it's late to the hand and the hand is already tanyao dora2. The plan of "I'll call this hand to tenpai, or get to tenpai myself and dama" should already have been made. Riichi here isn't terrible or anything though.

January 19: I have no concrete answer for this. The pon doesn't really slow the dealer down, calling from opposite would have been a bigger deal. Of the waits, I'd choose 36s since the 3s are behind a 4s kabe. But not ponning, the 5s is hard to use by opponents because you have many 46s and drawing 7s would give you the optimal 58s wait... I guess the 36s wait is the best option.

Thanks for your input. After analyzing the latter situation again, perhaps we can continue the discussion on the waits a little furthur.
I was always under the impression that late in the hand, if a tile is not showing on the table, that it is dangerous and less likely to be discarded.
I usually try to take this into account in order to maximize my chances of winning both ways, either by ron or by tsumo.

In this case, there are no 5s or 6s showing on the table, leading me to believe that they are not likely to be discarded by anyone.
There also two 2s and two 3s, along with a 4s and 7s, which leads me to believe that the 3s is the one most likely to be discarded.

Looking at this in conjunction with what is in my hand, and seeing that there are 2 , 2 , 1 , and 3 available,
how does one decide on which wait is more efficient, the 36 or the 47?
I chose the 47, ended up with a ron win on the 7, but had to toss the 6 (breaking my rule) to do it.
Is that why the 36 wait would be better even though there would probably be less tiles available (for a ron win) since the 6 most likely won't get tossed?
(Or do you not even take these things into consideration?)
