Poker seems really messed up.
I've had my flush beaten by Rose's two pair and three of a kind.
An Ace-low straight was beaten by Rose's pair of tens.
My AKQ73 was beaten by her A9753 "high card".
I'm repeatedly having the game erroneously telling me I've lost despite having the blatantly better hand, and every time it favours the AI.
What's worse I've gotten a full house four times only for her to have the instant-win card with a bunch of rags every single time! In fact, Rose in general seems completely clairvoyant. I've played a fair bit of poker in my time and she very consistently hero-folds every single time I improve after my change. If I go to showdown with a premium hand, she has the instant-win card 100% of the time. Conversely, if I'm dealt an instant-win card, she immediately mucks 100% of the time.
Sample size is limited of course, but all evidence points to her being able to see your cards face-up.
