The number next to the action – ie Raise 1 – refers to the number of callers or limpers before your turn, so in this case if there is one limper before you, you would raise. The fourth column shows your action from the Big Blind in a raised pot. The second column shows your action from the Small Blind in a raised pot. The second column shows your action from the Small Blind in an unraised pot. The first column shows you potential hands you may play from the blinds.
