Welcome on my blog. I will provide you with my thoughts on chess.
My fundamental is straight:
If you will make good moves, you will not worse your position.
Is there any use of that kind of obvious sentence? - You could ask.
Yes, there is.
Let's say, that you are in the middle of chessgame. You are asured, that all your moves were good, but now your adversary make unexpected, seem like strong, move. Your confidence is crumbling. You can not see good answer.
But if you made good moves, there is good answer! Stay confident!
