What are the most demanding starting hands?

[R Gibert]

What are the types of starting hands that are the most demanding skill-wise to play? From late position? From early position? With a deep stack of over 100 BB? With a stack of about 30 BB? Please explain your reasons for your opinion and if you could, please rank the different types of starting hands by order of difficulty.

And a slightly different question is, which types of starting hands do you believe are the most misplayed ones under the various conditions mentioned above?

Please answer the above questions in the context of NLHE. TY

Weak player dig their biggest holes with unsuited Broadway hands and no kicker high cards, Ace rag, K4s etc. When a decent player finds himself playing these they're still lots of chance for expensive error. I'm quite cautious with the junk hands but I play mostly short stack poker.

Shouldn't this be in the PL/NL HE section then?

I was all up for saying KK23 in Omaha 8 or better, then saw your condition!
