How to remember chess openings effectively

When he was asked what single quality is required to become world champion, Garry Kasparov replied "a powerful memory".A powerful memory can help beginners learn gambits, defences,traps and much more.... 

Asimple opening such as Ruy lopez can be remembered by a simple movie each scene representing a move.Here I show my readers how to remember the najdorf variation of sicilian defence.

the moves are :

1. e4     c5
2. Nf3    d6
3. d4      cxd4
4. Nxd4   Nf6
5. Nc3     a6

we know that

A=1

B=2

C=3

D=4

E=5

F=6

G=7

H=8

now our only task is to code the moves into numbers:

eg e4=54 and c5=35 and Nf6=Horse(n) and 66

now what to do with the nos???

simple; we have to use  Number/Shape System to remember the moves

I will give the key for this in my forgoing article

That's nice, but nobody has any problem remembering what the Najdorf is.

The problem arises when you try to remember about a book's worth of theory after those first few moves.

Instead of numbers, try words. Words are easier to remember than numbers

Actually even i tried words but they weren't effective.

I was going to come in offering advice, but since OP is acting like he knows it all already and can teach others there's clearly no need. 

The way to study opening IMHO is to :

1/ Play them a lot.

2/Try and understand the ideas.

3/Analyse your own games where you play them. REVIEW your own games from the critical moments. First without an engine then with one.

4/Play through and (try to) understand the masters games.

Usually an opening variation can be described by a pawn structure plus optimal piece development idea, and some subsequent game plans. If you have those in mind, finding the "correct" move order is more or less a calculation problem - mainly thinking about tactical threats and management of tempi as well as avoiding or forcing certain variations that transpose into something else. I guess if you know the "ending" position and have analyzed the possible earlier "crossroads" and traps, you'd come up with the exact moves easily.

There's a great book called Moonwalking With Einstein which shows a system of effective memorisation. It's not a chess book, but it does touch on the importance of memory in chess.

When you first start off playing chess, after you know the general rules of the opening, I think it might be advisable to learn the themes of different pawn structures. For example, learning about what types of pawn breaks you might want to play for in a Caro-Slav structure will help you in the Scandinavian, the Semi Slav and a tonne of other opening lines. It helps you formulate plans without memorising theory.

This is the first idea that came to my mind when I read the OP's post. It seems that when I understand the ideas behind the moves, they are much easier to remember.

I agree with ziggy and kleelof. Ideas, principles and pawn structures are more important than specific lines. In OP example, what if opponent plays 3. ...Nf6?

Just use your smartphone....problem solved.

To be honest, my smartphone is pretty f'ing stupid.

I asked it to explain the theory of relativity and it just asked me if I wanted to play cookie crush.

Must be android :)

Indeed, it is. 

hehehe

you see, there are different methods for learning something, the same way

As kikvors said, you don't need to learn the moves actually. The theory begins "after" those beginning moves. That's what you need to get an idea of.

That reminds me of the software Chess Position Trainer. Although it says 'Chess position', it is mainly for learning openings.

Is that you in the pic with the headphones on?

That's Erik.
