Yeah it’s a little different because the human mind isn’t procedural — you can perceive multiple cards at once, at a fuzzy resolution. You look at a hand and see “okay an ace, 3 face cards, some other cards” then scan to resolve. So an optimal algorithm needs to take that cognition into account.

That's the sort of thing I hand in mind, yes. Should probably write what I think I'm doing down.

Though in that specific situation, the sufficiently smart and motivated could probably infer hand information.
