i was about to say start registering for heads up sit n go's all day long.
or try for some small shootouts that are 3 or 4 max when they come around.
the
odds are a lot different between full tables and heads up... 10 max, 9 max, 8 max, 6 max all have different ranges that you should be working with.. with the biggest ranges being heads up.
everything that is played heads up is blind vs blind, where all the craziness can happen. maybe try a large ante game sometime, too?
