Regrouping necessary at certain points
Many a time it is necessary to evaluate a position properly and decide to change the positioned pieces in different direction or pattern or adjust them on different squares.
This is known as regrouping of pieces. Many a time the pieces have to retreat all the way back to the first rank and it is like embarking on another journey.
In the game which follows, White is better off and it is interesting to see the way he decides to regroup his pieces mid-way through the game. Thereafter the pieces once again harmoniously co-ordinate to clinch the game.
