Usually we talk about 2 skills when it comes to chess improvement, pattern recognition and logical reasoning. But in fact there there are 3 skills which must work harmoniously together:
- Pattern recognition
- Logic reasonic
- Trial & error
Trial & error plus logical reasoning form a feedback loop. Trial & error is meant for probing the position and to look at lines at lightning speed. It is a bit of a Troyis-like activity.When an error is identified, logical reasoning should come up with alternatives. From these three skills, logical reasoning is the weakest link by far. Yet trial & error needs exercise as well.
