The player with two aces and a seven had aces-full with one ace gone, so he could not lose. On sixth street, the dealer burned, gave each player a card, and then mucked the deck by mistake. So the cards had to be reshuffled in order to deal a seventh-street card. The player with the trip threes caught the fourth three to beat the aces-full. The professional player with the aces-full never blinked, never said an unkind word to the dealer, just took the beat, and went on to the next hand.
Poker is a game of human beings.
If you take the human element out of poker, which some people have done in computerized games and even with computerized dealers, the game is not the same. One of the things which saddens me the most is to see people that I care about in the poker world win a lot of money, enough to give them an opportunity to have some freedom and live a more normal life outside the poker room, and then to find out later that all of their money is gone because they didn't do anything with it. One of their problems is that, because they spend so much time at the poker tables, the money has no value so that they don't recognize that they need to separate their poker money from their other money. Rather, they should get involved in the decision themselves, just as they use their decision-making skills at the poker table. If they took just 10 percent of their win and put it into an investments program, they would have a significant guaranteed income that would allow them to play poker forever without undue financial stress.
