Well, the math is pretty straightforward tbh.
I'd disagree with this. Whilst we can calculate the static odds of a certain hand, it is extremely difficult to calculate on-the-fly, in the middle of a game, what your chances are of getting a certain hand - and of other players getting certain hands. The people-reading is certainly a key part of being a successful player, but the ability to even approximate the odds in the middle of a game is a vital vital skill. I think I'm an okay poker player, not bad but not great, and I do try to estimate very rough odds whilst games are in progress - it is an extremely difficult challenge.
I wondered some time ago whether the following improvement to poker websites could be implemented: each player sees the probability of her/his hand and the probability of someone else having a better one. Can this be properly counted, taking into account not the cards which are open on the table and those the player currently holds? Would it be useful?
I think this is a cheat, really, I'd not be in favour as it takes away some of the player's expertise. It's like if there was also an on-screen counter showing running percentages of how often each player has bluffed.
