Tenhou Stuff Special Edition – 2017 NARMA Winter Online Open

Hey!

Yesterday I participated in my third big Tenhou tournament. Two previous ones were the Nikaido Cup and IORMC 2016. Tenhou tournaments are fun and a bit less tedious than real life tournaments. Can’t say I prefer one type over the other, different experiences.

I had a great time playing in the NARMA competition. I think it was well organized (props!). I played to the best of my abilities and I’d say I’m fairly satisfied with my playing, although I could’ve finished in top 20 had I not messed up my last game. I was very unlucky a few times and one game ended in I think E3 xD Those are the things you can’t help sometimes…

What I can do is to search for my mistakes and learn from them. However, this is not enough. I certainly have some blind spots which I’m unaware of. That’s why this blog post is being created. I hope strong players will help me find even more mistakes!

Here’s a playlist of my games so you can watch them yourself:

And now on to some crucial situations in which I messed up/wasn’t sure what to do. There were some others but they were mentioned in the videos so I won’t repeat myself.

  1. First off, a story of one hand… This is a type of hand where I rush my discards and often mess up.

Seeing 2x6p discarded, I wanted to reinforce my 557p by keeping both 5p. Lone 5m was to keep my Dora/567 SSK chances. 9s looks more like a full set rather than a pair + 79s. I discarded 5s (too many pairs).

te2

I said I had too many pairs… then discarded 7p…. It was inconsistent with my reasoning from the previous screen. I think I gave up on SSK too easily. 1p/5p could’ve been discarded there.

te3

I went on discarding 1p and decided to keep the pair of 5p as my final pair. Here I discarded 8m becaue of the overlapping 7m wait there. Souzu shape kept developing. Now it’s 45 779 99.

7s

I had nothing to lose so I pushed 9m against Riichi and now 7s because I’m iishanten waiting on 47m 369s. I got to tenpai on my next turn with 6s and declared okkake Riichi. Unfortunately, Kamicha got a Ron on Toimen right after that.

My point here is that even though it all worked out, my discards were not really carefully considered every time. I didn’t process all possible ways in which my hand could’ve evolved. It was my auto-pilot mixed with rushy reasoning.

What do you think of my discards? I think that 7p was a mistake. Knowing that my hand would’ve ended up the same is just hindsight bias.

ahaa

That’s one miserable situation xD I was considering Chinitsu (Ittsu). Direct Mangan from Toimen or any Haneman was what I needed. I didn’t notice San Ankou potential yet (I realized it later) xD Riichi, Tsumo, San Ankou with Doras woud’ve been enough. Should I have taken that tenpai and insta-Riichi in hopes for Tsumo?

With 4m dead, Kan 2m is just as good a wait so I chose suji the suji trap.  Aggressive opponents are more likely to resort to suji. That wait gives higher value too.

Would anyone go for damaten Pinfu here?

I was in the lead so I decided to bail this Mangan. Kamicha looked like he was relying on Pinzu. On the other hand, my wait was good, it was only E3 and I had enough points to afford a Mangan/Haneman Ron from Kamicha. Perhaps I should’ve just insta-Riichi that? What about if that had been S3?

I went damaten on this one. I thought that 5200 was good enough. I think the main reason for damaten should’ve been wait improvement. 2457s not only improve my tenpai, they increase my hand value as well (Pinfu/Ippeiko). Insta Riichi isn’t that bad either since I’m falling behind and aggressive play is advised in such situations.

My wait didn’t improve but I  got aka 5p and kept damaten. Someone else won before me.

Discarding 6s here for a possible 345 SSK isn’t a good option here, is it?

Seeing kabe on 6p and with 5p suji against Kamicha I decided to okkake Riichi. Do you think that was a good decision with only 2 outs?

7.

7 pairs isn’t usually a good pursuit hand but I was desperate here so I think dropping 3m to chase that Chiitoi Dora2 was the best choice even though I dealt to Shimocha.

8.

My last Oya turn. Would you push 9s here?

9.

nie-pchaj2

This is just bad, don’t do that! Dora soba push with Yakuhai nomi against Oya Riichi on ippatsu turn is asking to get raped. I had so many genbutsu!

BTW: I won that hand later. Oya must’ve been really pissed off…

Now here’s my personal favorite which cost me top 20:

wewerr

I know I shouldn’t have rushed that atozuke Yakuhai nomi in the first place but I embarassed myself further by dealing Sha to feed Kamicha-san xD Yeah, I still do stuff like this  although much much MUUUUCH  less frequently than I used to. Progress!!! hahaha

I hope you had fun reading. Feel free to leave a comment 🙂

May Yakuman be with you!
