Can someone explain why I could not win? (look at my hand, in reach and the immediate discard before me, not the actual win)

The only stick I discarded with 9 of sticks. The player before me discarded my winning tile 3 of sticks, but Tenhou did not allow me to ron.

I am aware that by furiten rules I am prevented from winning on 6 of 9 of sticks. But why is 3 of sticks also included?

It's interesting to read everyone's comments about this position. As spine said, west is [highly likely to be] waiting on chun and there is no way for me to win without discarding that tile. Betaori is definitely an option and no way an incorrect play in this situation. Tenhou is correct to say that there are only 6 draws remaining, however after seeing both north and west discarding dangerous tiles after south played riichi, south actually has up to 18 draws and not 6. This is where we could play the chun to let us pass the round cheaply. The best move here really comes down to risk vs reward and your own opinion on how much they weigh.

Each option has a few scenarios that may happen. From most likely to least likely, by playing betaori:
1. South wins off east or north - Again we can say its most likely a mangan hand. Not too bad of a situation for us here but we are still within firing range especially since south becomes the dealer in the next round.
2. North plays riichi - Theres no reason for north not to play riichi if he is in tenpai and not playing betaori. This give us another candidate for a possible haneman.
3. South wins a haneman off west - The best case scenario for us. Ends the game
4. South tsumos - The worst case scenario when playing betaori; we can assume a minimum mangan hand which puts south within a few thousand points of us.
5. Draw - A good result for us.
6. West wins off south or north - We keep our lead and go into the next round!

By playing chun:
7. Deal into south with no doras - 1300 points.
8. Deal into south with 2 north tiles - This becomes a 40fu 3han hand which turns out to be 5200 points.
9. Double ron - Probably the only thing that made me use up my thinking time. If south had the other chun tile, he could also play riichi with a single wait on chun as his only chance to win the round. Unlikely, but still a possibility.
10. Nothing happens - Very unlikely lol.

With north and west not playing betaori, I though that a majority of the times, 2nd or 3rd place will gain on us a significant amount if I played betaori. By playing the chun, I though there would be about a 95% or so chance i will deal in with a maximum of 5200 with at least 50% of it being only 1300 points. With this, I believe chun was the best play here.

Also for those who didn't know, tiles that are 1 or 2 above and below from the riichi tile are consider very dangerous tiles to play. In this example, 4p 7p would be considered bad tiles to play due to the 556p pattern. There is also the 554p pattern but the 3p has already been played here.

No, if you move the mouse cursor right over that middle area -- you'll see the point differences between you and everyone else.
