Unfortunately the previous posters explanation wasnt perfect, as the most important aspect of the chart is that you are assuming your opponent knows your exact hole cards.

The chart assumes you are playing a game with blinds of 1 and 2. You are in the SB and have only two options, either to move allin or to fold. The number in the right most column is the number where you are +EV to move allin with the given hand, assuming you have that many chips or less AND assuming your opponent knows your cards. This means that if your opponent calls with every single hand that beats you, its still +EV to move allin with these hands as long as you have less chips than the right hand column.


What this basically does is prove beyond a doubt that it's terrible to fold certain hands headsup with certain stack sizes, because even if your opponent knew what you had, your push would still be +ev.
