Honiisou: Difference between revisions

'''Honiisou''' (or honitsu) {{kana|混一色}} is a standard [[yaku]]. Normally translated as a "half flush", this yaku features a hand composed only of honor tiles and tiles of a single suit. If the hand contains no honor tiles, then the [[chinitsu]] yaku is counted instead.

Naturally, it is easier to form honitsu when your hand starts with many tiles of the same suit. It is often unwise to break up a completed sequence of a different suit to force honitsu (though if you ''really'' need points, it's possible).

Most yaku which allow one suit of tiles are compatible honitsu. This excludes [[sanshoku]] and [[sanshoku douku]], which require use of all three suits. Honitsu is not compatible with [[chinitsu]], because every chinitsu hand is honitsu. Honitsu combined with [[tanyao]] or [[junchan]] would actually imply chinitsu instead, since there would be no honours.

Honitsu is commonly paired with with [[yakuhai]] (calling [[pon]] for honor tile speeds up hand), [[ittsu]] (which already has 9 tiles of the same suit), and [[shousangen]] (which already has 8 honor tiles).

This yaku is affected by [[kuisagari]]. The hand value decreases by 1 han when open. Honitsu can still be used for open hands, though. When combined with other yaku and/or dora, the -1 han is not a significant loss of value. For example, honitsu + yakuhai + dora 1 is worth ~7700, and the +1 han from closed only brings it up to 8000.

'''Bakahon''' {{kana|バカホン}} is a slang term for a honitsu-only hand with [[naki|open calls]] and no dora. This hand only scores 2000 points, which is not worth the amount off effort required for honitsu. (Since every 1 [[han]] doubles the score until 8000, even something like open honitsu + 1 dora is worthwhile.)
