With your hand on south 4, I would've bailed straight away upon seeing riichi. If you had a halfway decent hand, it's really a tossup on whether to attack or defend or not, but your hand was worth 1000 at that point, which wouldn't have helped matters even with a riichi=bon. You'd then have to go in...

My original logic with this hand is that if I riichi and 1st/4th discards 3s, I'd not even have enough to get 2nd place (5100, tiebreaker goes to lower ranked player IIRC). if I don't riichi, I can let pass any 3s, and still get 2nd place by ronning 6s off anyone/ron 3s off 2nd place/tsumo anything....

Left hand player disconnected, thus will be blown away at the end.
