Most Classic Chess Techniques

This is probably the most classic chess technique ever, and by far, my favorite! What other classic chess techniques are there? Feel free to share!  

Your "classic chess technique" is to hope your opponent learned the game yesterday?

You must be blind to not see it coming, very easy to predict, very easy to block... but i did that several times and it worked every time it was hard for me to believe....

In a completely different situation, when the knight forks both the king and rook I'd consider to be a classic move; it actually does happen and can be planned without a way of preventing it that wouldn't cause as an extreme a loss.

Here is the situation AitoHitoshirezu was talking about. You see since the queen is in danger, it makes things more complex. The loss of the rook could have been prevented, but not in this diagram.

Here is almost the same technique, but with a different victum.

my dad can occasionally beat me when he plays well but i beat him with scholars mate and different variations of it 4 times in a row!!!

This is a classic mate using 2 rooks at the end of a game 

I find it hard to believe anyone would move the knight to c5...with nf6 it just seems like a wasted queen move.

Wow I was totally expecting something else when I read "Classic Technique". Especially the technique part.

Whenever your opponent moves, ask yourself why he/she moved that particular piece. Also, stay alert! You never know what will happen next unless you focus. Finally, don't give up.
