Calculation in Chess

Calculation in chess is a wonderful skill to develop, as well as being an essential one in almost any position.

Its probably a major difference between the various levels of chess player, with a GM seemingly displaying a grasp of calculation that is far in excess of anything an amateur can achieve.

This is perhaps the key : a GM is a professional chess player, so although a GM displays this incredible skill, it is probably not innate. 

There might well be a natural core available, but I suspect it is extensive practice and experience that allows the skill to develop to the levels seen in GM-play.

I found the below demonstration and exposition of calculating skills by GM Nadezhda Kosintseva to be quite amazing.

She takes a position (shown below) and proceeds to analyse it deeply and fully, bringing out a remarkable amount of information from what appears to be a straightforward position at first glance.

Its a long video ( an hour ) but worth watching for the way she analyses and how the methods can be learned.

Helpful ( or maybe, educational ) to think about the position first, before watching.
