What is Passar Battaglia?

Passar Battaglia is an old term that used to be employed in chess literature, particularly in Italy. It translates to 'pass battle' or 'pass the battle', and it was used to indicate a positional chess strategy where a player tries not to engage in a direct confrontation with the opponent's pieces (pass the battle), typically waiting for a more advantageous situation to arise. More research may be needed as the term is largely obsolete and rarely used in modern chess commentary or instruction.
