Rules of chess ,are very different from the laws of nature. Laws of chess are not applicable always ,but just the most times.
Now its time to answer your question on traps and best moves
The best defense in chess will be very often an attack ,which may give you the chance to beat your opponent.
There is no best trap.There are just traps that are very good ,with many victims.
Chess has been played for 500 hundred years,and a theory has been created: the chess theory.
According to this theory ,there are 2 basic rules,
which you have to apply the most times in a position on the chessboard.
The first rule says that you have to develop your knights,bishops and finally rooks AS FAST AS YOU CAN.
Queens must be the last piece developed.
The second rule says that you have to CONTROL THE CENTER WITH PAWNS.
The center of the chessboard are the squares e4 ,d4,e5,d5
Therefore,give importance to the following advice ,which can be of extreme importance when you play against your friends.
IF YOU ARE PLAYING WHITE AND YOU CAN TO THIS ,PUT YOUR PAWNS ON e4 AND d4 this will give you more space ,and the best chances to win.
Your opponent (the most possible)will play moves like pawn to a6.,pawn to a5 etc
IF YOU ARE PLAYING BLACK AND YOU CAN TO THIS PUT YOUR PAWNS TO d5 AND e5,this will limit his chances.
If you are playing white the following move is the most popular
1. e4 ,which means you move the pawn in front of your king 2 squares. If you are playing black and your opponent has played this move the best defence is pawn to c5 but also good is pawn to e5.
A popular trap ,in which black looses
1.e4 ... e5
3.Nxe5 !(good move) ...fxe5
4.Qh5 check(if black plays ...g6 he looses his rook after Qxe5 check.) ...Ke7
and black will loose easily after Bc4 check
its not easy to find out how ,but your opponents will not play the best moves...
Just have in your mind a good "defense" which can be applied almost no matter what your opponent will play
1.Nf3 ,2.g3 ,3.Bg2,4.0-0,5.d3,6.Nbd2,7.Qe1,
