fluorescenthippo,
I guess the only thing I can say about the equilibrium ranges is, well... the math is the math.
Remember that while the equilibrium ranges are calculated to be unexploitable, they are not guaranteed to be the optimal strategy for a specific situation where your opponents might deviate from the equilibrium.
If you have specific knowledge about an opponents range, you certainly need to apply this information in order to get the real "answer".
Its a kind of "apples to oranges" thing to compare equilibrium strategies to what you believe to be a correct strategy based on your knowledge of actual player tendencies. For this reason, if you think that 10% is a better calling range than 20% in your example, then that may be true, but I would have to argue that it is more likely a coincidence and does not represent some kind of algorithmic advantage of an ICM-based Nash approximation over the Predictive Simulation in SnG Solver.
You say that no one would be calling A6o in the BB, but
if UTG is pushing 38%, then they
should. Likewise, if UTG if only pushing 28%, then SnG Solver agrees that the BB
should fold A6o instead...
Spots like this are still going to come down to how well you can put your opponent on a range, and for this SnG Solver can try to put you in the ballpark, but you still have to do the rest of the work yourself.
And thanks for the feedback!
