The Fundamental Theorem of Online Poker Games

The Fundamental Theorem applies universally when a hand has been reduced to a contest between you and a single opponent. It nearly always applies to multi-way pots as well, but there are rare exceptions, which we will discuss at the end of this page.

What does the Fundamental Theorem mean? Realize that if somehow your opponent knew your hand, there would be a correct play for him to make. If, for instance, in a draw online poker gamess your opponent saw that you had a pat flush before the draw, his correct play would be to throw away a pair of aces when you bet. Calling would be a mistake, but it is a special kind of mistake. We do not mean your opponent played the hand badly by calling with a pair of aces; we mean he played it differently from the way he would play it if he could see your cards.
