LOL!  Oh boy! You have no idea how deep the rabbit hole goes. For example: How would you detect if any player cheats in only two or three moves? How much time and resources would it take to analyze such games at scale?
Sooner or later, your PvP platform will become EvE (Engine vs Engine)  , just like every other platform providing such games. This is exactly why no major casino is providing PvP chess. Even chess platforms with the best resources and skills to prevent cheating are not providing PvP chess for money. Even their tournaments do not have attractive prize money, and only high-rating chess players participate (GMs and IMs cannot cheat repeatedly against each other because they are playing under their own names and their reputation is at stake).
You can argue the same for poker, but it is still not fully solved (and luck plays a major role), although online poker is on the decline for precisely this reason.
