there is a lot of common knowledge that is not taught in the tutorial. like:

playing cards that are clued as colors

only discarding cards that are to the right

saving cards

and so on.... ( i know there is much more but cant list them all)

how can they learn all these things unless they come across a player that is kind enough player to teach you these things.

On this link you will find everything you need to know about hanabi.

Be free to ask me any questions in PP and I would like to answer all of them.
Best regards.

while it can be very useful (and I used it myself when learning), be wary that it describes H-Group convention, while BGA mostly uses (Layered) Finesse. there is a lot of overlap, but also some differences: for example we don't have Chop-Focus with color on BGA. but go with it, you'll get corrected for the conventions that are not used here just like I was

The main idea is: Discard your oldest (unclued) card first, on the assumption that if it had been useful it would have been clued somehow earlier. Since new cards come on the left, that's the rightmost card. Conversely, when you decide which card to play, it should be the newest (applicable) card.

There are of course exceptions, nuances, context, etc. But I think the rest of the "conventions" should be more or less logically derived from that. For instance, a 5 clue on the rightmost (chop) card is probably a save, and by extension one should assume that any number clue on the chop is probably a save... which makes a color clue probably not a save.
