This is something I hear a lot and am wondering how it's specifically defined.

Is blocking continues:
I have JJTT and the board is JJTT. Because I have double quads, the opponent will have virtually no hands interested in moving forward on this board.

Or is it

I have TTTT and villain needs a T to make his gutshot, which he's never getting. And because of this I block him from hitting the card that makes his hand.

Thanks
