In sim 2, the SB opens 100% of hands. The BB's optimal play against this is to fold 0%, call 56% and raise 44%. I only ran this sim for 30 min or so, but I think it's clear that the sim's adjustment is to play more hands and play those hands more aggressively preflop.
This would appear to contradict the idea that we should adjust to loose preflop play by tightening up. This may be due to the simplicity of a blind vs. blind scenario or that we only have two players in the hand, but I think it's a good starting point to extrapolate a more complex multi-way preflop decision.
Ironically, even after ridicule from the community, it seems that the practitioners of no gambol, no future might be on to something!! Welcome your feedback and thoughts.

First of all, mad respect for running your own sims and putting in the hard work of thinking through complex aspects of the game for yourself. As I learned the game and moved up in stakes, I too often relied on other people’s representations re sims, etc. and frequently what people published turned out to be dead wrong, disproved later by others who, like you, did their own “homework.” I don’t run sims anymore for myself, so, honestly, reading your post made me feel a bit lazy
That said, this is a topic that I have read a lot about over the years, and—again—a great deal has been written on it, so I would encourage you to seek out that work which was produced by better minds than my own.
For a number of reasons, your blind vs. blind opening range sims will not provide you full GTO strategy for playing back at opponents who are too loose. There are a number of factors missing from your sims that must be considered and accounted before we get to GTO.
And I’m sure I misstated/grossly-oversimplified my position on this topic earlier. There are certainly times when our opponents loose play makes it +EV for us to see more flops with a wider range of hands, etc.—especially when our opponents are preflop limping OOP, etc.
The last time I tried to suggest LHE tools/materials on this forum to someone, I got trolled/dissed/etc. And the truth is that others on here will have a better knowledge of what up-to-date resources are out there which cover this topic, so maybe someone could direct JLot to some of those, please? That said, I’ll see if I can find a couple of links to post a bit later, and I’d definitely try to find previous discussion threads on this forum that relate to this topic. Those threads will contain a ton of information, and even if much of it is contradictory, it will at least provide you a more comprehensive framework for working through this problem for yourself.
