Based on my studying of the population tendencies, as well as reviewing the results of a number of different players, I believe that deep stacked almost every hand strictly prefers to min-raise--the only exceptions I've found are that suited broadway hands slightly prefer to limp-flat. I also found though that the EV differences between limping and min-raising are very small and therefore there will certainly be reads and populations where instead limping will be slightly better. Shallower there will be more hands that prefer to limp read-less, but still the EV differences will be small compared to not having that range.

Certainly you should not deny yourself of limping though once you've become and experienced player, and it's definitely something you should explore and look into. My video pack never says you cannot our should not limp on the button! Simply that expectations tend to run pretty close and min-raising is easier for new players so I focused on that aspect of button play. The benefit of building a limping range will be very small compared to that of building an overall solid strategy pre-flop and post-flop so I chose to spend more time on the latter. This is definitely a fantastic topic though, as there certainly is a lot of ways that limping can be used given reads or at shallower stacks to squeeze a bit more edge out of your button play. It's definitely not necessary for beating Spin and Gos, but can definitely be a valuable weapon in your arsenal.

I'll certainly look to building some content regarding button and SB limping since it's a topic that seems to have a lot of interest in it :)

Yes those adjustments seem very extreme! The T9o versus the open shove was still fairly read-less, and population tendencies point to very tight open shove ranges at that stackd depth, so while we want to adjust to our opponent we need to adjust away from the population tendencies which will make it still a fold--that being said it's certainly a very close spot. 

Folding 54o and J6o is certainly too big of an adjustment as those are very strong hands on the button! Read-less we shouldn't fold anything at that stack depth, so to adjust we can begin to fold some hands, but J6o and 54o will need a lot of reads since we have so many weaker hands we want to fold first before we make such an extreme adaptation.

86s is closer, and we could definitely elect to open shove there. However, it's still fairly deep and limping is again a lot better versus the population tendencies, so it's still usually going to be a limp unless you feel very uncomfortable post versus villian, or you have better reads that villain shoves >50% of the time over your limps.

Q6o 9.75bb is not at all close to a push--open shoving will be very similar to open-folding in expectation vs most players (it's a 9.6bb Nash push), while limping with 72o is better than open-folding versus most players and Q6o limps way better than 72o. Even if we have to fold more than average we will still be doing significantly better limping there than open-shoving.

Lastly KTo is super close. Shoving there for thin value will be very similar in EV. I slightly prefer flatting but it's likely because I'm so confident post but shoving would be absolutely fine.

Hope that helps!

Glad to hear you're finding some more Spin content out there! I know there hasn't been much posted, and it's great to get other perspectives.

I talked about limping on the button earlier, but I wanted to expand a bit more. I'm definitely convinced playing those wide hands is incorrect. I've seen a ton of databases with very poor results with them, and done enough modeling versus population tendencies to be pretty confident that in todays games playing pretty tight on the button is better than loose. Limping doesn't actually help deep, especially with the hands you mention because they are significantly worse in 3-way pots than 2-way and when limping you play 3-way 50% of the time as opposed to about 30% of the time when min-raising, so there's no reason to suspect that limping them is a more profitable way to play them readless--in fact my research indicates the opposite, which would make limping them an even bigger mistake than opening.

Perhaps if Primo has enough sample you could ask him to share his results with the bottom of his range? It would be great to have another data point as right now all the data indicates he's incorrect.

SB vs BTN is another spot where I've seen very poor expectations with weak hands in practice. In theory it's tempting to play because of good pot odds, but the truth is that due to the BTN's strong range and our positional disadvantage equity realization tends to be very low in SB--it's very tough to value bet (which increases realization), and it's very tough to avoid being put in bluff catcher spots (which lowers realization). The exception is drawing hands (like 54s), which I definitely agree you can call very wide with--drawing hands will almost always be able to profitably call bets without being made indifferent, and when made they can always value bet, so they do a good job realizing their equity and can take advantage of the good pot odds offered.

As for SB vs BB, I definitely agree limping a lot is a good way to approach SB play--especially vs stronger players. That being said, there are still plenty of hands for which min-raising is strictly better so it's important not to go too far into limping world and forget entirely about min-raising :)

Hope that helps, sorry again for the delay in getting to all your questions.

Most players call too much on the river, so generally big river bluffs tend to be plays to avoid. I usually try to instead find profitable spots to set up smaller river bluffs, or just small flop/turn bluffs that shut-down later. This lowers our in-game variance which can help with win-rate maximization, as well as generally doing a better job of exploiting the population's tendency to call too much.

Good catch! It appears there are a couple of typos--65s should be set to 10 in the Push/fold chart (the footnote on it is correct), and T7s should be set to 11. That being said don't worry too much about this change--the EVs of shoving those hands at 10 and 11 respectively are very close to 0 at equilibrium, so the ev difference of beginning to shove it at 8bb or 9bb respecitvely is extremely small and on the order of approximation mistake. These push/fold ranges do not have mixing indicated and so it's possible that the hands would be mixed around those stack depths, or appear/disappear in the range at fractional BBs. In the end nothing to worry about for actual gameplay--you won't go wrong following the original chart  :)

In the end the adjustment chart should still make sense for those hands--don't jam them at all when BB is short.

Let me know if you have any further questions.
