On the other hand, we've run out of hands!
I don't think my Dad invented the words 'Expected Value' but he sure did make
it a common term in gambling circles. It has become the standard, talking not
only about video poker but almost every other game as well.
The goal of the term 'Expected Value' was to look at all 'the other hands' and come up with a common way to decide which 'other hand' was the one you wanted to follow. It looks at all those little differences between pre-draw hands, eliminates emotion and boils it down to a single number. The pre-draw hand with the highest Expected Value is the one to follow.
As the example above shows, Expected Value doesn't tell us which hand will win more often or lose less often. It calculates a weighted average of the likelihood of each post-draw hand using the payback of that hand. Again, it must be realized that these are all averages. Over relatively short intervals (dozens to hundreds), the actual numbers can vary greatly from those on the tables above.
When utilizing Expert Strategy, it's not important to memorize the Expected Value of any particular hand, but rather to memorize the order of the hands in the Strategy Table. While sometimes it comes in handy to have a rough idea of a hand's actual Expected Value this is more to level set our expectations of that hand. Our tables above, however, show that sometimes these numbers can be deceiving in terms of what to expect. A higher EV does not necessarily mean a more frequent winner. For this, we need to turn our attention to an outcomes table used in the calculation of the EV as shown above.
Becoming an Expert Player is a long process. Over the past few weeks, I have
covered the basic principles of Expert Play as explained using our 'three-legged
stool' model. Over the coming weeks I will continue to delve more deeply into
each of the three legs. If there is any particular topic that interests you
that you'd like me to cover, feel free to drop me a line at compuflyers@prodigy.net
