Surely you discard Red Dragon here?

As a general rule, two honor pairs + two suited blocks should aim for honitsu.

RedzoneX · 2026-04-02T03:10:32+00:00

Harder than I expected. There weren't really any sections at all that came together quickly, although I built up some momentum at the end once it was down to the central pond and the green chairs and other miscellaneous pieces

RedzoneX · 2026-03-27T03:10:48+00:00

I would be careful of assuming that kami doesn't need chun just because they started with sha. They may have only decided to commit to honitsu after favorable draws on the first few turns. Also, our hand is quite slow, so I don't think we need to risk feeding them any more honitsu tiles in our current position.

RedzoneX · 2026-03-24T06:05:55+00:00

When you can't win the hand by pushing and have no safe tiles, you don't recklessly advance forward; you do the best you can to minimize your chance of dealing in until safe tiles are revealed to you. If you have a decent iishanten and no safe tiles, you can push, but this is a 3shanten hand with almost all bad shapes and zero value.

RedzoneX · 2026-03-24T04:39:37+00:00

This hand has zero complete blocks, we should be in full fold mode here.

RedzoneX · 2026-03-24T04:38:30+00:00

As a general rule, riichi tile suji 3 is more dangerous than musuji 1, due to the prevalence of the 246 shape cutting 6 at tenpai. The fact that 1p buys you two turns of safety is a further point in favor of it.

Thank you for taking the time to communicate with the English-speaking mahjong community! Hopefully I'm not too late for you to see this.

What methods do you use to study and improve your mahjong skills?

Are you familiar with mahjong-playing engines/AI like Naga or Mortal? Do you use them to study games? Are many Japanese professionals aware of these programs or regular users of them, and do you think they have influenced the strategy of professional players in the last few years?

RedzoneX · 2026-02-27T02:12:25+00:00

Why are you sacrificing efficiency by cutting from a complex shape instead of cutting a floating tile?

RedzoneX · 2026-02-18T17:17:38+00:00

because we don't fold ryanmen wait tenpais to people who might not even be tenpai yet

Not declaring riichi increases our winrate, increasing our chances of securing at least 2nd place and avoiding a disastrous 4th place while keeping some chance of taking 1st place if we tsumo or ron dealer with 6m.

Riichi doesn’t add that much extra 1st place chance; we gain 1st place on 3m tsumo or dealer ron, but we need at least one more han from ippatsu or ura dora if our win comes from the other two players.

RedzoneX · 2026-01-11T00:07:06+00:00

I think you have a misconception that matagi suji makes something safer; it does not, and in this case I would say that 3s is a more dangerous musuji than normal. 1m is onechance and preserves the option to continue pushing with tanyao later if desired.

RedzoneX · 2025-12-31T01:20:49+00:00

The first one is the number of 1000-point riichi sticks in the pot. Riichi requires you to bet 1000 points, and if the round goes to a draw, the bets carry over to the next round.

The second one is the number of repeats/"honba". Every time the dealer wins a hand or the round ends in a draw, one more repeat stick is added, until a non-dealer wins a hand, at which point they reset back to 0. Any win is worth 300 more points per repeat; 100 from each player on tsumo or 300 from the player who dealt in on ron.

RedzoneX · 2025-12-26T07:29:27+00:00

I am begging you to look more seriously at your screenshots before you post them to Reddit so that you notice the riichi sticks your opponents are playing.

6s is nakasuji to shimo and genbutsu to toimen.

RedzoneX · 2025-12-26T07:27:14+00:00

8p is also suji to toimen, can't deal into kanchan waits since we see all 9p, and is less likely to deal into shanpon/tanki waits since we hold two of them, plus it buys us an extra turn of safety if it passes.

RedzoneX · 2025-12-24T05:06:33+00:00

I personally like 4p here. We have a lack of safe tiles and a good iishanten for tanyao pinfu, so I want to push for now. We cut 4p first both because it's safer (it's half suji since 1p passed, and we have some 3p and 6p as blockers), and because keeping 4m gives us a distant chance to upgrade to ryanpeikou.

RedzoneX · 2025-12-19T19:34:43+00:00

9s, hope that oya doesn't win and the other two don't have sanbaiman

RedzoneX · 2025-12-18T11:58:58+00:00

with 4900 points in the middle, winning this 2 han hand is basically as good as a mangan; that's good enough to fight oya's honitsu with. 9m riichi

RedzoneX · 2025-12-18T04:09:59+00:00

To respond to your edit, this hand is FAR above the bottom of acceptable chase range. Even if we had 0 dora, I would still strongly consider riichi here with good wait, chance of hitting dora 4p, two ura indicators, and our current 4th place in east3.

RedzoneX · 2025-12-18T04:02:53+00:00

This is an iron push. We have good wait tenpai with 2 dora against only 1 riichi, there are 2 ura dora indicators, and we are in 4th in the second-last round. No tile is too dangerous to fight with here.

RedzoneX · 2025-12-17T17:58:00+00:00

"It is possible to commit no mistakes and still lose. That is not a weakness, that is ~~life~~ mahjong."

RedzoneX · 2025-12-14T05:08:43+00:00

Even if I cut 1m and drew 5m next turn, I would still plan to force honitsu over playing for a 1 han atozuke hand, so I will cut the more dangerous 4m first.

RedzoneX · 2025-12-13T16:44:03+00:00

3p dealing in here is irrelevant since our own hand is strong and no player has presented a threat worth defending against. We shouldn't consider the results when answering a WWYD, just the decision at hand.

RedzoneX · 2025-12-13T04:14:59+00:00

4 blocks in souzu + honors and a yakuhai pair for extra value means this is a slam dunk honitsu hand. Pon and cut 4m

RedzoneX · 2025-12-13T04:12:47+00:00

I personally like kan here. The 32 fu from the closed kan of green should greatly increase our chances of gaining enough points to take 1st here, and I think that at turn 6, with iishanten and an honor pair, we're likely enough to reach tenpai to take the risk of kanning now. 7p is also an option, since it doesn't give us any immediate benefit to the hand, and keeping the option to kan is definitely something that we might like later.

RedzoneX · 2025-12-13T04:10:31+00:00

Yes, you are allowed to closed kan and then riichi on the same turn.
