Konno's Kolumn No.4

[gemma]

Here\'s hand B that Konno posed as your homework. Happy reaching!



Dora:

[Trotskey]

I'd discard the , on a 1,4, or 6 since it puts us in a pinfu tenpai.
Granted, one of those waits is dora, so it may make it hard to win on
that tile, but if we draw one dora, it won't mess up our hand.
However, I'd still tsumo this hand on a or a .

I would probably only go for endless if a dangerous middle tile forced
those s out.

This is from Konno’s Kolumn #4, and not #5 as Gem wrote.
And the question here is not "what would you discard" but "what would make B into its “final shape”", in the goal of declaring riichi.

The final shape would be a sanshoku 456 + pinfu (+dora) I think:


or any other minor variation...

I think Trotskey said all other things to say about this hand.
