I'm a little confused by what the SHC says about speculative and mixed hands when playing in middle and late position respectively.
Example: if you have 66 in middle position, you call if 2 or more players call BB, but you must fold if only 1 player calls.
If you have an A8s in late position, then the same applies.
Why is this? Shouldn't it be the other way around? If 2 or more players call BB, then isn't there more chance of you being up against a better hand? The only reason I can think of is that it's worth calling for a bigger pot.
