jam fold tables

If you are fortunate enough to reach the final stages of a tournament and you end up playing heads up with the blinds going up,  it becomes imperative to know the optimal strategy based on how many big blinds you have left to play with and whether you should jam (go all in) or fold. Understanding this concept will allow you to optimize your chances against an unknown opponent who may outplay you post flop.  Bill Chen and Jarrod Ankenman, in their book "The Mathematics of Poker"  have researched calculated and outlined a game theory optimal play for heads up with under 20 big blinds.  So what is all this about?. Well.. when you are under blind pressure, you will reach a point at which you will be wondering if you should move all in or wait for a better hand. If you fold and wait for a better hand you may get it or your may get a worse hand which will have you wishing you had gone all in with your previous hand. So it turns out that for optimal play, as your stack / big blind ratio dwindles, your jamming hand ranges get wider. With 20 big blinds or less, any Ace is a jam. Any king down to K-9 is a jam. K-6 is a jam for 15 big blinds or less. 11 big blinds or less u can jam with K-2 .
