"You can’t win an argument with a troll
There are trolls online. Not the fairytale kind that sits under bridges: we’re talking about the mean, nasty individuals who use online anonymity to be cruel, spread their own brand of hate, destroy reputations and products, and generally try to upset and crush as many people and companies as they possibly can.
Trolls agitate to start fights between friends or strangers; they torment those struggling with illnesses or with the loss of a loved one, people unsure of their identity or their looks, or any other weakness a troll can find. They disrupt forums with off-topic comments, brag nonstop about themselves, ridicule the thoughts of others or insert controversial comments to disrupt conversations.
Trolls spread lies, deceive and cause damage, and they enjoy every minute they can make someone else miserable. They may be obnoxious teens, but more often than not they’re seemingly “normal” adults who use internet anonymity to shed their veneer of decency and show their ugly selves. Trolls are basically cyberbullies on steroids – cowards afraid to show their face but nastier and more dedicated than garden-variety bullies. They are often fairly tech savvy, willing to dig up a comment or information from your past to distort, thereby “justifying” their actions.
If you’ve spent any time online, you’ve probably run across trolls even if you didn’t know the term. You may have tried to reason with them, be nice to them or virtually shout back at them. Don’t bother. You’re more likely to win an argument with a tree than you are with a troll.
What trolls need
In order to attack others, trolls need a victim pool and a public forum of some kind, and they usually want an audience.
This means trolls gravitate to anywhere...."

29. FAQ: Pawn capture En Passant Help : enpassant (Note: For members new to the game of chess.)
"When a pawn tries to sneak past an enemy pawn to avoid capture, there's a move of which many beginners are often unaware.
Take a look at the accompanying diagram. A black pawn has advanced to its fifth rank. In the adjacent column, a white pawn, still on its initial square, is preparing to make a two-move jump to avoid capture.
However, the en passant rule prevents a pawn from avoiding capture by another pawn in this manner, and allows the black pawn to capture the white pawn exactly as if the white pawn had moved only one square.
This move can only be carried out on the move immediately following the white pawn's move.
Note that only another pawn may capture en passant, the move cannot be performed by any other piece."
