It’s rare, but every once in a while you get those rook hands that you would be willing to bid so high with. What do you do if you opponent has bid 170 though? Do you bid higher?

Well, looking at the above rook hand, you obviously want to take the bid.  You are going likely be of no help to your partner if they take the bid, or to even stop your opponent if they take the bid.   So it is absolutely essential to win this bid.  This particular hand, you are missing both the 14s in your suits, but you have both 1s and 13s in both the trump suit as well as your off suit.  You even have the 10 covered in green, so you are likely to only loose say 10 points per hand if you lose the 14s in both colors.

You are going to trump any other color that is played, so you really don’t expect to loose points elsewhere.  So really, I would be willing to bid up to 180 in a max 200 round, with the possibility of taking all the points if my partner or the kitty has 1 or both of the 14s missing.
