On this website, you can play heads-up (two person) no-limit Texas
Holdem. The blinds are 50 and 100 chips and the stack sizes are 200
big blinds (i.e., 20,000 chips).

Unlike most poker games, your stack resets to its full size after
each hand.

The baseline statistics compare how you did to how Slumbot would have
done with your cards in your seat. A positive value for baseline
earnings mean you did *better* than Slumbot would have done against
itself given your cards and sitting in your seat.

Here's an example with a single hand. First Slumbot deals out cards
for the board (let's say AhTd4c9s3h), the button (let's say AdKh) and
the big blind (let's say TsTc). Then Slumbot plays itself on these cards.
Let's say that the players get all-in (since they both have strong hands).
So the result is -20,000 for the button.

Now you get to play Slumbot on these same cards. Let's suppose you're
the button. Perhaps you put in 8,000 chips on the early streets but
manage to fold to a large bet on the river. Your outcome is -8,000 for
this hand.

Your *baseline* outcome is how much better (or worse)
you did than Slumbot did against itself. Your baseline outcome here is
+12,000 which is the difference between -8,000 and -20,000.

Your baseline statistics should better reflect the skill with which
you play. They eliminate much of the luck due to getting good or bad
cards by measuring your relative performance to another player playing with
the same cards.
