5 cards of the same suit is called a flush.
When ou have 2 hole cards of the same suit it's just called suited cards.
Ace and anything suited (Axs) is strong-ish, but not something you want to play from early position.
Kxs is in the same boat, but there are times that I will throw either away, even from middle or late position.
I just what I'm saying is It All Depends.
