also, amaazon.jp is having a kindle book sale. mahjong books are dirt cheap. I haven't decided what to buy yet, but if you've got any requests I might consider buying them and sharing

Use pic related instead, it's a lot easier to read and has basically everything you need to know

Yep, it came right before I discarded the 6m. Discarding it felt dangerous but toimen was still 1shanten thankfully.

To be able to win (by ron or tsumo), your hand needs to fulfill at least one winning condition (=a yaku) that isn't just "4 triplets and one pair". This is generally not an issue when your hand stays closed as closed hands can call riichi (a yaku) or that tsumo with a closed hand is a yaku by itself (menzen tsumo)

In your picture, you opened your hand with that chi of 456sou so you don't have access to riichi or menzen tsumo, and have no yaku. To win, you could try to aim for a tanyao (no 1/9/winds/dragons).

You can call ron on anything that completes your hand as long as it's a valid hand (4 triplets and 1 pair) with a yaku

Play more to remember the combinations more easily and see which can easily be combined with which. Here's a few hints though:
>go for 3 to 6 han hands when you can, these 4000-5000 to 12 000 points hands are what actually make a difference
>for most hands, your best bet is to keep closed and combine Pinfu with Riichi and maybe Tanyao (not hard), Iipeikou (a bit harder) or even Sanshoku Doujun (really hard)
>if you have a dora/akadora, keep it, you have okay chances to draw a second one to make it a pair or to make a sequence with it. If you have to throw it, make sure it's not too late in the game and no one is ready to win
>For hands with lots (3-4) of pairs, either chiitoitsu (7 pairs) or Toitoi (all pons, better choice if you have triplets instead of pairs or if your pairs are easily ponnable, like terminals or honors)
>Lots of terminals/honors? Try chanta/junchan, can be combined with toitoi or sometimes Sanshoku Doujun (you'll often end up with a 789 for every family)
>Lots of one numbered family? Honitsu/Chinitsu.
>Dragon/Bonus wind pair and you can't make honitsu or chanta? Your hand will probably a cheap fast one unless you get 2 or more dora

Somebody posted this Yaku chart last thread, I split it in half and made an easily printable two-page PDF out of it: https://a.pomf.space/duayoauvbzyo.pdf
Sorry for the large file size (8MB), I didn't want to bother with tinkering until it looked good and was a small file size so I just kept each page as a big, uncompressed PNG.

Calling Pon/Chi opens your hand. Opening your hand helps you going faster but makes the hand worth less points and you might not be able to win at all with an opened hand.

To be able to win with your hand, it needs to fulfill at least one of pic related requirements (yaku). When your hand stays closed, it's easy: drawing your winning tile with a closed hand is a yaku called menzen tsumo. If you want to win by ron, a closed hand can call riichi when it's one tile away from winning, which is also a yaku.
If you open your hand with Pon/Chi, then you have to make sure you complete at least one yaku. The easiest are yakuhai (having a triplet of dragons, or having a triplet of your seat/the round wind) and tanyao (no honors/terminals : only 2345678).

Of course yaku stack up and give your hand more points (han), so say you have a closed hand with yakuhai, that you call riichi and draw your winning tile to win by tsumo, it'll be worth 1 + 1 + 1 = 3 han.

Keep the yaku list with you when you play so you can memorize them little by little.
