HP (Yaku) Explanation – Flushes (2)

From: http://blog.jpmahjong.net/read.php/529.htm

In this section we’ll focus on the important points when calling tiles at the time of going for a flush hand (one suit hand/somete).

Flush hands can be pretty confusing because all tiles are concentrated and the shape is complex, so it takes some effort when we have to call tiles. Calling tiles should make it faster for us to win the hand, but with inferior calling skills it will only make it more difficult. I will now introduce the basic principles for calling tiles.

Rule 1: Make sure it gets the hand closer to ready (tenpai)
If a hand two away from ready gets to one away from ready, it has gone one step closer to ready and will make you win the hand faster. Getting closer to ready is the vital point of calling tiles.

1c2c3c5c5c6c8c8c9ceast
Player to our left discards 1c, we don’t need this tile.
We already have 1c2c3c, and calling 1c doesn’t move us any step closer to ready, and we also lose a valuable chance to draw a tile. Calling a useless tile is worse than passing on it.
Readers should note, there are times where we should call tiles even if it doesn’t get you closer to ready, but that’s more advanced theory (shape) which doesn’t fall within the scope of this article right now.

Rule 2: After calling, the hand shape doesn’t change
2c3c3c4c6c6c8c8c9c9c
In this hand, we should call any tile except one.
This is, bumping (pon) 3c after someone discards it. The reason is that the remaining 2c4c is empty (because we’re already using three 3c, there is only one left)
What if the person to our left discards 3c, what should we do? As long as there are no other especial situations (for example if all 8c9c were already dead), we shouldn’t touch this tile. Because 2c3c3c4c is a good shape, calling this tile doesn’t move us any step closer to ready and it also changes the shape of the hand erasing a good shape.

Another example.
1c2c3c4c5c5c6c7c7c9c2d2b9b
There is no problem aiming for a full flush with this hand, but when the person in front of him discarded 7c, this player bumped it. This, I wouldn’t recommend.
Look carefully at the composition for this hand:
1c2c3c+4c5c+5c6c7c+7c9c
Forming a set with 7c breaks up a complete group (mentsu) and also an incomplete group (taatsu) which could have made another group; the gains do not make up for the losses. The 4c5c5c6c shape is not the same now that 7c is on a set, and we only remain with a lone 9c to use and maybe letter tiles (jihai) as well to finish this hand. All this did was making the hand more painful and difficult to win.

If this 7c was discarded by the person to our left, there would have been no problem (you may chow/chii this tile).

Rule 3: Pay attention at the way you call tiles.
In flush hands we have many tiles of one single suit in our hands, so when the person to our left discards a tile we normally have more than one way to call it.
1c2c3c4c4c4c5c6c7c7c
Person to our left discarded 3c, what should we do?
The right answer is calling it with 1c2c, and discard 7c, thus it the remaining shape is 3c4c4c4c5c6c7c with a four sided wait (2c3c5c8c).
A mistake many beginners make is calling this with 4c5c and discard 7c too anyway, ending up with 1c2c3c4c4c6c7c, waiting on only 5c8c.

As far as flush hands concern, we’ll drop this here. In the next article, we’ll discuss pair-based hands (Toi-Toi (all bumps) and Chii Toi Tsu (all pairs)).

Garthe’s Commentary

Yeah, no kidding on the whole hard to read waits thing. It reminds me of a hand I had in the semifinals of Masters that is just one more classic example of me winning by playing wrong.
I had already won the first 2 games so my spot on the final table was already virtually assured. The real contest was between Ogawa and Imazato for the second spot from our table.
The 3rd hand of the east round, Imazato Reached after I had gotten to ready with this
Active ImageActive ImageActive ImageActive ImageActive ImageActive Image   Active ImageActive ImageActive ImageActive Image
Dora was Active Image! Just waiting for Active Image, I was fretting over what I would do if I had a chance to improve my wait. It’s fun to play with everyone watching but nerve-racking too as I really didn’t want to make a mistake in front of everybody.
What should come but Active Image. Throwing Active Image seemed like the obvious choice but for some reason, I just couldn’t see what I’d be waiting for besides  . Even now I had to get my tiles out, put the hand on my bed and start taking out pairs to finally see that I was also waiting for Active Image .
Unable to find the right answer at the time I opted to just stick with the current crappy wait and discard the tile I’d just drawn. That prompted a hapless Ogawa to believe that Active Image would be safe and he discarded my winner. 16,000 points plus shock and amazement oohs and ahs from everyone watching as Ogawa’s final table hopes went down the drain.
I’m not saying that my play was necessarily wrong. There are definitely reasons one could argue it is a viable play. I’m just disappointed that I only made the right play by not being able to see all the plays that were available.
Go ahead and separate out your groups to see what you really have like he did in the 3rd example of the column. It will be a dead giveaway that you’re going for a flush but chances are the other players will be on to you anyway. It’s also a little embarrassing to have to do it that way, but what’s a little embarrassment compared to 16,000 points! You still get the last laugh.
