Many players like to discuss positions using moves. Knight to G four, bishop to F five, pawn to h6, and so on. But behind those moves there are of course ideas. And it is those ideas you need to find the moves! So let us talk about ideas instead!
Ideas are born in wishful thinking. You wish that something would work. You wish that you could get a knight to f5. Then you look and see if that is possible in practice? Do you have a knight? Yes. Where is it now? On f3. Can it get to f5? Yes, with Nf3-d4-f5 and Nf3-h4-f5. But black has a pawn on g6. Can it be bound to the black king on g8? Yes. With what? A queen. Where is the queen? On d2. Can it get to the g-file? Yes, with Qd2-g5. So that is the idea. Nf3-d4, Qd2-g5, Nd4-f5.
Ideas of course need knowledge and experience. Been there, seen that and hopefully done that. That is what you get by going through grandmaster games. You see and memorize ideas, also known as patterns. You see how the pieces act in harmony towards a common goal. Then, you can derive through analogy a similar idea in your position.
Here is an example. Black just moved Kc8-b8 to avoid Nxf7. Now white did some wishful thinking. "I wish I would grab the rook on d7 with Qxd7 because the rook on d8 is pinned to the black king on b8 via Rh8-d8-b8. But I cannot do that because black also has a queen on c7. Can I chase that queen away somehow? Yes! With Bd2-a5! Thus the idea Ba5 was born!" We also added the idea Nf4-e2 check to make the point that black does have some defense ideas. After Qxa5 black is probably lost. But after Nf4-e2+ white has to make a few good choices before getting an advantage. In the example below black managed to almost equalize the position! So after Ba5 black should calm down and look for ideas too! It works both ways! Thanks for reading.
