Hi Yash.
Sound advice but it can be a bit flexible.
In certain circumstances, sometimes the correct move is not always the best move.
It often depends on who you are playing.
Wild attacking players hate defending. Iron logic postional players dislike
messy positions where they cannot grip on a plan.
There are quite a few examples of where a player explains he chose a move
not to suit the position but to cross their opponent.
The classic and most often cited example is Tarrasch V Lasker 1908
from the master of such strategy.
Lasker played 16...Rc5
Kasparov wrote something like Lasker played this to get Tarrasch out
of his comfort zone.
Lasker wrote:
"The Rook must be dangerously exposed so as to draw the brunt of the attack."
Any other Black move in the above position subjects Black to a miserable
defence and would fall in with Tarrasch's boa constrictor style which he was very
very good at. The 'correct' moves are either 16...Nf6 and 16...Nc5 but are they the best moves?
