Morning All, Why is only the Big Blind used in measuring stack size? It ignores the effect of the Small Blind and antes in each round of play, If you have 20 BBs you only have 12.5 rounds of play before being blinded out. I realize formats have changed somewhat, still curious about the BB to stack size ratio reasoning.
Since small blind is often just half a big blind, its effect is implicitely taken into account.
For games with antes, you may want to learn about Harrington's M (ratio between stack and initial pot)
-
A small addition here, M is useful even without antes as exactly as the question mentions it takes account for the orbits of play. As David mentioned, have a look at M. This is the concept you've basically hit on without probably realising it. – Grinch91♦ Jul 22 at 9:28
