兵bīng不bù厌yàn诈zhà

Literal
war does not tire of deceit
Figurative
In war, and in any contest, deceiving your opponent is fair game; often invoked, half in jest, to excuse a trick. All's fair in love and war.

Where does 兵不厌诈 come from?

It comes from the Han Feizi, chapter "Nan Yi." Before facing the larger army of Chu at Chengpu, Duke Wen of Jin consulted his adviser Jiu Fan, who replied that a man who cares for ritual never tires of loyalty and good faith, but in battle one never tires of deceit, so the duke should deceive the enemy. Another adviser, Yong Ji, objected that deceit pays off once and then no more. The duke followed Jiu Fan and won, yet when rewarding his men he put Yong Ji first, since his advice would serve for generations. Today it names a general principle, not a specific maneuver like 声东击西.
