I'm with or2az on this one. I'd cut the
. My goal is two han to get into first place. There are many possible ways to get it: 7 pairs, double yakuhai, yaku/dora, toi-toi, honitsu being the main possibilities.
I'd probably aim for either yaku/yaku or yaku/dora with a backup of either toi-toi or honitsu. But it depends on what comes up first. If another
comes then I'll go for a quiet chitoitsu (ie no reach) otherwise I'll open on any of the pairs that gets discarded or if the
comes from my left. Would then discard the 3-pin, which while it inhibits toi-toi, all we need is 1 extra yaku on top of one of the yakuhai (we'll need at least one to complete the hand unless we discard one of the pairs). The one yaku can either come from a
giving us the red 5 Dora, or if worst comes to worst and we don't get a 4p then we can discard the 3p and 5p and get our one (two) yaku from honitsu. As soon as we open we'll need to discard three tiles to get to tenpai (including the one from opening) and the 34m is easier to complete than the 35p. Note that if I end up opening on the
then I'd discard the red 5 and aim for yaku/yaku or toi-toi.
Slight tangent:
This is just my thinking behind why I chose the 3p as my second discard.
I'd say the 33p and 35p are roughly equal in ease to complete. The 3 pair only has two tiles to complete it, but has twice as many "draws" since you technically have 4 possible places to get it from (your tsumo and all three opponents' discards). While the 35p has twice as many tiles, but only two "draws" (yours and West's discard) . However the 34m has twice as many tiles as the 35p while having tbe same number of draws. Making it more favorable than it and by extension the 3 pair.
Masa: Yup, it uses the Mahjong Fight Club rules which includes two red 5p.
