Scenario 1:
Let\'s say we\'re playing with Fight Club rules, so suuanko is a single yakuman while suuanko tanki-machi is a double yakuman, and you can stack multiple yakuman.
From what I understand, it\'s a fairly common practice for the dealer to save a couple seconds at the start of the hand by taking his 13th tile and his first draw in one grab - once everyone has 12 tiles each, the dealer takes the 1st and 5th tiles from the wall.
Now, let\'s say the dealer\'s first 13 tiles are:













and his/her first drawn tile is a

Would the dealer be able to claim tenhou + suuanko tanki-machi for a triple yakuman if:
A. He/she didn\'t take his first draw early (as described above)?
B. He/she took his first draw early but kept it separate?
Scenario 2:
The dealer\'s initial 14 tiles are:














He/she immediately declares a kan on the chun and draws a 7sou. Can he/she claim tenhou, or only rinshankaihoo? What if this occurred with a non-dealer on the first turn, with no previous pon, chi, or kan by other players? Would he/she be able to call chiihou or renhou?
Scenario 3a:
A player wins with the hand:














Now, I can see two ways of counting this hand:
1. Count the 111222333sou as 123 123 123, for iipeekoo (1) + chanta (1) + chun (1) = 3 yaku.
2. Count the 111222333sou as 111 222 333, for sananko (2) + toitoihou (2) + chun (1) = 5 yaku.
Would the player be able to claim iipeekoo + chanta + sananko + toitoihou + chun for 7 total yaku and a haneman, or can he/she only claim option 2 for a mangan?
