"When you are weary with the weight of studies, if perhaps you are pleased not to be inactive but to start games of skill, cunningly the pieces are disposed on the open board and battles are fought with soldiery of glass, so that now White blocks Black, now Black blocks White. But every foe yields to thee, Piso; marshaled by thee, what piece ever gave way? What piece on the brink of death dealt not death to his enemy? Thousand-fold are thy battle tactics: one man in fleeing from an attack himself overpowers him, another, who has been standing on the look-out, comes up from a distant corner; another stoutly rushes into the mêlée and cheats his foe now creeping on his prey; another courts blockade on either flank and under feint of being blocked, himself blocks two men; another's objective is more ambitious, that he may quickly break through the massed phalanx, swoop into the lines and, razing the enemy's rampart, do havoc in the walled stronghold. Meantime, although the fight rages fiercely, the hostile ranks are split, yet thou thyself are victorious with serried lines unbroken or despoiled maybe of one or two men and both thy hands rattle with the prisoned throng."
