In the Sept. 23 issue of Card Player magazine (see scan above), there's a short interview of Andrew Brokos (check out his excellent blog called Thinking Poker.) He has cashed in the WSOP main event for the past three years including a 35th-place finish in 2008.
Adding to your arsenal:
When asked about throwing some wrinkles into one's game, he says:
I think a big problem that a lot of people
settle into is playing mechanically. If you
are open raising and three-betting with the
same hands, all you are doing is passing
money around the table.
If you look at the history of online poker,
the people who have made a lot of money are
people who started doing something no one
else was doing.
What I recommend is to start doing something
that you don't ordinarily do. It might even
be things that only bad players would do.
It might be min-betting, min-checkraising,
limping into pots, overbetting the pot,
and so on.
Your opponents are used to someone who
raises their big blind from the button.
They know how to deal with that. They
don't know how to deal with people over-
betting the turn when the board pairs,
or something else they've never seen
before. A lot of times people are going
to make a mistake.
After the game, ask yourself how did
it work out? Were you using it in the
right spot? Why did it work? How did
the guy respond? All that gets you
thinking about the game, rather than
going through the motions.
