Working backward to solve problems - Maurice Ashley

One myth is that grandmasters can see ten or more moves ahead.

The truth is that in just the first four moves, there are 318 billion moves you can make. This is too much even for grandmasters, so they use various techniques to be able to look ahead.

• Take a group, a chess position, and see what possibilities can come from that group.
• Pattern recognition, which is remembering a lot of positions that look similar and extrapolating truths from that.
• The stepping-stone method is to take a position, freeze it in your mind, and guess the next position.
• Retrograde analysis, which is, in order to look ahead, it pays to look backwards.
