Stealing bring-ins
Third street: door cards and bring-in define the steal/complete decision. High doors steal more; live pairs complete for value.
When everyone has rag upcards and you've got an ace up, completing as a steal is profitable if they fold too much. If the bring-in is a maniac who never folds, steal less and value more.
Steals still need a plan for when called. An ace up with two down garbage cards becomes awkward fast.
