The only tricky thing I see in autoincrement/decrement operators (and I'm quite surprised that no one here pointed that out) is the difference between prefix (++i) and postfix (i++) versions. I also believe that autoincrement/decrement operators are slightly more efficient, in general. Besides this, I think the choice is based mainly on aesthetics, especially in javascript.

In Settlers of Catan, I sometimes try to ask people if they want to trade a certain resource, tricking them into revealing the approximate amount of that resource in everyone's hand. After this I play the monopoly card. This has on some occasions not been received very well.

Is this fair play?
