First of all thanks to Mark for taking the time to put up this poll.
Second, on the final board your RHO opened 4
♠ and all passed. Since we'll be South on all hands, perhaps opener can be moved to East.
Third, it is perhaps better for Mark if you send him the bids only. Open a separate thread if you want to discuss this or that hand in particular, as we did with previous polls. As usual, discussion is most welcome, so you're encouraged to do that.
Fourth, in #3 you're playing BBO standard with whatever gadgets the system allows. I think that means no negative free bids, Gonzalo
Finally, I'll put up a message in the main forum advertising this poll.
