"Also people have said doing the chess puzzles is a good tool for learning."
Without a doubt this a proven method of improving and absorbing ideas.
However John Nunn in the January 1993 BCM (British Chess Magazine) says
the fault with this method is you know there is something on so you look for it
"Before you look, first you must see!" is a war cry of Jacob Aagaard.
Nunn suggested the best method is to play over the unannotated score of a
game and see if you can spot what you think is a missed shot and then look at it.
This way you sharpen your up your sixth sense, the ability to sense/know/have a
hunch something in 'on' and we are at a critical stage in the game.
When the good guys offer advice we must listen and I can see the benefit of this.
However Nunn's suggestion that you play through unannotated games from the
Informator contains a slight flaw. What if there is no missed shot!
What is needed is a book of unnoted games where a tactic was missed,
you have to spot it and having 'sensed' something is on you then dig it out.
I used a smaller version of this idea in my latest bloggy thingy
Blog Post 492
by giving just a short fragment saying a good move was missed.
Going though the whole game I would have stopped around about
movess 25-28. (Indeed I did I when I first played through the game)
to see if there were any sac-sac mate ideas on. (apparently not).
Also maybe Black could of made more of the e-pawn being pinned.
(around about move 32 - I give the full game below. )
The blatant missed shot happens in the ending. To do such a book justice
would be to skip through the whole game to see if something leaps out.
If not then through it again. (too much like hard work for the average player
who is always looking for a quick fix but I'm sure it would be beneficial.)
I once asked a very good player what chess book really helped him improve.
He answered 'The Golden Treasury Of Chess.' I knew that book it is
full on bare games scores with a brief intro. No notes.
I asked "What happens if you spot something that was not played?"
and before he could reply I answered my own question:
"....you have to work it our for yourself." This was met with a smile and a nod.

The whole game I used in the blog and not just the missed winning trick in the ending.
