Maybe not memorizing but calculating odds can help.
depending on the cards on the table and on your hand you can try and calculate the odds of other players to have better hands than you.
definitely not easy, but feasible.
Calculating the odds of possible outcomes is absolutely necessary when you play poker, and, yes, it's feasible. Experienced poker players do not use calculator for that, it happens automatically in their brain. Of course, since luck is involved, you can know nothing about the odds and still win, but the probability of that is very low.
nice trick on checking response times of users.
Yeah, just one example. You can't call a big raise instantly, when you have nothing. You should consider bluffing or folding, and it takes time.
