先看trick在merriam-webster collegiate dictionary里的第一项解释：
1 a :a crafty procedure or practice meant to deceive or defraud 为了达到欺骗目的的狡诈手段或行为 b :a mischievous act 恶作剧:PRANK c :an indiscreet or childish action 轻率或幼稚的行为 d :a deceptive,dexterous,or ingenious feat; especially :one designed to puzzle or amuse 具有欺骗性,灵活性或巧妙性的技艺,尤其指带娱乐性和迷惑性的技巧*a juggler's tricks*
再看cheat
1 :the act or an instance of fraudulently deceiving :DECEPTION,FRAUD 欺骗的行为或欺骗的例子
总结：cheat多指损人利己的骗,trick多指恶作剧或娱乐性的小把戏
当然两者的含义有交集
