For purposes of analysis and strategy, I cannot see how one could correlate poker with trading. This is just my opinion, but I think a static deck of cards, even several static decks in any one game, holds only so many probabilities, and those remain static to the players at the table so long as the deck is not shuffled. The market is also full of probabilities, but is shuffled constantly by millions of emotional people pushing the magic buy and sell buttons, and those unique, updated probabilities are dynamic after each trade, never to return as the same set of probabilities, ever again. Emotions do not affect what cards are waiting to be dealt. Emotions do rule which button most traders push.
For practice? Heck yeah, I'll bring the pizza.
