Multiple Hand Ranges
The idea is that it's often difficult to put someone on a single range, and that different players will have different ranges in the same spot.
It comes from the same place as ranges came from in the first place, which is taking a step back from looking for a single hand that your opponent could have. With multiple ranges, we're taking another step back, and coming up with a few different possible ranges that our opponents could have.
I'm going to give a basic example here of how this is useful.
Let's start with getting all-in preflop. I'm playing 1/2 No-Limit, Full Ring. I open on the button, I get 3bet, I 4-bet, and my opponent shoves. What's their range? Well, that depends on the player. It could likely be {KK+}, {QQ+/AK}, {JJ+/AK}, or maybe {99+/AQ+}. That's a good place to start. A lot of people will fit into one of those ranges. How about bluffs? Any of those ranges could include bluffs once in a while, but not everyone will bluff shove. Bluffs would likely be pairs, AXs, or suited connectors.
If we have a good idea of what possible ranges are that we can be up against, then we can also get an idea of what our equity vs. those different ranges are. That would let us have a better idea of what hands we should be calling off with vs. different players.
I'm going to use JJ as our hand, go through the equity we would have vs. different possible ranges, and show what we'd want to do vs. a shove: (the right play can also change based on bet sizes and stack sizes)
[no bluffs]
{KK+} - 18.568% (fold)
{QQ+/AK} - 36.190 (fold)
{JJ+/AK} - 36.585 (fold)
{99+/AQ} - 50.184 (call)
[some bluffs]
{KK+, A2s} - 30.938% (fold)
{QQ+/AK, A2s} - 39.515 (??)
{JJ+/AK, A2s} - 39.784 (??)
{99+/AQ, A2s} - 51.234 (call)
Depending on what range your opponent has vs. the one you put them on can make a difference of how big of a mistake you could potentially make. It would be a big mistake to get in vs. {KK+}. It would be a small mistake to get in with 35% equity. It would be a clear win to get in with >50% equity.
How likely are the different ranges your opponent can have? How big of a mistake is it to call and be wrong? How big of a mistake would it be to fold and be wrong?
I'm planning on making a video on this idea soon, and go into it more in depth. Let me know what you guys think, and if you have any questions!
