原文 Many people play pocket jacks timidly. They fear an unfavorable flop, such as one or two overcards and no jack. Since these bad flops occur relatively frequently, they conclude that they are better off waiting until they know the flop is favorable before they gamble. They are wrong. Pocket jacks are a premium holding, and they usually win far more than their share against four loose opponents. While unfavorable flops come relatively often, so do favorable flops. You will flop three undercards about a third of the time and a set an additional twelve percent of the time. Those times that you flop a set, your pot equity will often be over seventy percent(against four players). Sets come infrequently, but when they do come, they are extremely profitable. Remember, when you raise for value against four players, you are not betting that you will win a majority of the time. You are basically betting that you will win more than twenty percent of the time. Unless one of your opponents has a bigger pair, you will almost always win more often than that with jacks. When one of your opponents does have a bigger pair, you will still sometimes outflop him. Your edge is big. To maximize your winnings, you simply must gamble in favorable spots like this. The upsides of waiting to see the flop do not compensate for your failure to make the pot bigger.
