Above board

二月16日才在cbc碰到一次，今天又在cbc碰到了。
今天有人回文說到
I agree fully that ALL officers have and are under the microscope. I also FIRMLY believe, that any officer doing their jobs well and above board, has nothing to hide from the microscope.

我完全同意所有的警官都被在顯微鏡下檢驗。我同時也深信，所以的警官不但要把他們的工作做好，而且不可以違法，沒有什麼不可以在顯微鏡下檢驗的。

二月16日的回文說到

I know a person who worked on the show and it is 100% above board. This guy goes out from desert to deep forest with a hand full of things, no food and no water. Then stays alive for a week and has to go to a set spot to be picked up. Glad these hikers had some supplies and made it through. Next time pack a few signal flares or road flares work as well.

我認識一個人在這個show裡工作，所以，這是100%是真的，沒有作弊。這個傢伙只帶著一些行李就從沙漠中出發到深林，沒有食物、沒有水。然後過了一個星期後又回到指定的地點。很高興這些登山的人有帶一些裝備，而且也渡過了難關。下次應該帶一些信號彈才對。

above board的意思是honest and legal， Openly - without any trickery.

據說這個board指的是甲板，有一些海盜船會假扮成普通的商船，而海盜躲在甲板下，誘騙人上船後，再來洗劫。 The opposite, 'above board' was considered to symbolize openness and fairness.

也有人說是來自賭博遊戲，如果玩牌的人把手放在桌子(board) 上，那麼大家都會相信你沒有作弊。

而'under hand' 就是 above board 的相反。

"He does it under hand."他不是用正當的方法完成的。
