Hi everyone. Here are different conventions to play Hanabi. After some games, it turns out to be very efficient, though a bit artificial. In the next message, you'll find a translation in French, Also translated in Italian, see further (thanks Jotaro 
Chop is still on the topright, excluding clued cards.
Instead of clueing the cards that we want to get played, well clue the position. Two ways :
1) with numbers : clue 1, 2, 3, 4, means play respectively first, second third and fourth card (from left to right)
2) with color : using the color order that stands on the board, which is : red / yellow / green / blue, we also clue the position : for example, cluing yellow means play your second card
Special meaning for 5 and white clue :
a) cluing 5 means : keep the card your about to discard, even if its a blank clue. So if you get 5 clue, your chop moves from one space to the left. If you get another 5 clue, your chop will move again on it's left.
b) cluing white to someone will mean : dont discard anything. We use this when we want to save more than one card, but the consequence is he / she will never discard again. If he / she gets a play within his / her cards, then the chop is the newest.
By mixing color / number, we try to keep only usefull cards, twinless if possible. Someday, thoose cards will become deduced as playable (or maybe discardable). In the spirit of thoose conventions, its ok to try and play a clued card if you have enough infos to know its either playable or useless. At least untill we get 2 bombs ^^
Finesse works the same way, and reverse / bluff could work as well, but you need to be carefull, it needs to make sense that it could be a reverse / is a bluff.
For example, you could bluff out a m1 with a green clue that doesnt color the third card. Is this case, the third card is a 2 step playable card, which is not multi, nor green. This card we be considered as clued and can't belong to the chop anymore.
Enjoy
here is SliceofBread's version for 2P-3P : "Number clues stay the same. clue 1, 2, 3, 4, means play respectively first, second third and fourth card (from left to right) 5 means save your rightmost chop.
Any color is a play clue, red untill white from left to right.
self finesse could be very usefull in 2P, but should be disabled if the person has to clue : full hand or 7-8 tokens. This way its easier to give a nonsense clue.
2p version is freewin if played well in my experience.
