I shall cheerfully bet at very high odds against this happening the next time I roll a standard die.

I almost said "so shall I, but... " - but then caught myself, because I may very well NOT bet at very high odds against this happening the next time I roll what I perceive to be a standard die.

If I believe my opponent is motivated to cheat, and capable of cheating in a manner that turns "roll a standard die" into "listen to my narrative interpretation of why whatever-just-happened means I won", then I'm apparently willing to take some of the resources I would have otherwise put on that bet, and instead put them on "watch out for signs of cheating and/or malfunctioning dice".
