Hey everyone me and my caoch were talking and he said when I go over a games I should look for key positions I can use at first I thought he meant look for the type of endgames that apper he said do that to but looking at the endgame and key positions are to totally different things. I want to know is how basicly What are key positions and what do they consist of when looking over a game? Also what are other things I should do and that you do when looking over games.

lev Alburt has two books, about 300 essential positions - and the second edition of some different positions.   excellent guides to 'key positions' to recognize readily.

you should get a couple copies of each - and have one with you all the time.

when you have five minutes time - open it and look at one or more of the diagrams as you learn them.

review never hurts either.

my coach says there are always key positions in a game just use the ones you need in your games from the peoples game you look over. I Mean what are key positions the ones you are describing just sound like puzzles from others games(not saying it in a bad way) unless those are what key positions are tactics in a game.

In every game that does not end in a draw, there is a moment when one side gains the advantage.

Alburt's book will give you an idea of several types of key positions.

A game that I'm learning with a kid that I coach (he selected the game), the first key position occurs after move 11. On move 12, Captain Smith castled kingside. Why? Was it wise?

 I learned that  whenlooking for a key position when looking over a game is basiclythe turning point in the game where one side gets an advantage so is did black attain theadvantage here and if so how  I think it's by his pawn stucture am  I correct.

Here, the advantage is black attacking from the 5th and 6th rank. The Queen and Bishop respectively. White has only 2 Knights. An analogy would the effectiveness of long range guns verses short.

I recently played against an opponent that had no idea what the Philidor defence was. Had they played like this they might not have lost. The pawn structure alone is not black's advantage. It's really the combination of both elements.
