Having online lessons with students, I see that a lot of them are doing mistakes in such general point of chess mastership as thinking process. Some of them, forget to think on opponents' ideas and blunder something; some of them don't make selecting of moves-candidates and miss very strong opportunities etc.
To help other persons who have the same problems I post these 5 steps of thinking process (as I see it):
1. when your opponent did his move and you start a thinking on yours one - ask yourself "what does my opponent want?". if you don't do this you are always under risk to blunder something.
2. when you know what your opponent wants - look at position and try to define all possible moves-candidates. this step helps you to avoid missing some good opportunity.
3. now it's time to calculate variations that start with moves-candidates. after calculating each line as far as you can - try to compare last positions of every line and find the best.
4. when you already see the best (in your opinion of course) move - does not rush with its making on the board. take another glance on the board and check if there is no blunder on the move 1 (at least; if you are more experienced you can check the whole main line of your analysis).
5. now, when you:
- are assured that you see opponent's plans (ideas, direct threats etc.);
- have seen all candidates-moves;
- caclulated and compared them;
- and are assured about non-blundering anything
you are ready to make the move finally!
I hope it will help some of you to improve your chess performances. As well, I'm ready to answer to all questions about this issue below in the comments field.
Enjoy chess - it's a great game!
