Two questions about the 2nd Charleston round - (1) how many bad tiles should I have to WANT a second Charleston, and (2) can you blind Charleston on all three of the second round passes?
Inspiration for Question 1 came the a few days ago at a Mahjong party. After the first Charleston I said I didn't want to go another round, but I wanted to courtesy swap three tiles. Someone at another table with A LOT more experience than I have heard me and laughed, saying that didn't make sense. According to her if I had three bad tiles I should go another Charleston. I chose not to because if I got a tile I wanted on the first round I'd be forced to give it up in round 2.
For question 2 I'm 99.9% certain you must pass three tiles for the first two passes of the second Charleston, but I'm actually finding conflicting answers online (I admit to not looking very hard). If you can blind charleston on all three passes then it seems you'd ALWAYS want to do a second Charleston.
Thanks! I just learned the game a little over a month ago and am still figuring things out.
