Question about a $1-2 NL black hole player

[Deltha]

This actually seems like a good situation for you and your friends. If the guy tightens up when he gets a bigger stack it should be much easy to put him on a hand. That said, just run him over. Raise his blind every chance.. if he calls continue bet and if you don't win the pot there re-evaluate.
Why ban a player if you KNOW how he is going to play? Adjust your game and bust him.
