Dissimulation
（重定向自Dissimulator）
Dissimulation is a form of deception in which one conceals the truth. It consists of concealing the truth, or in the case of half-truths, concealing parts of the truth, like inconvenient or secret information. Dissimulation differs from simulation, in which one exhibits false information. Dissimulation commonly takes the form of concealing one's ability in order to gain the element of surprise over an opponent.
