(Uncontested auction, starting with partner in second seat.)
Ok, this time the setting is a little different. This is the last set of a 64 board team match, and you were down 60+ before this set. You are playing precision, your opponents at the other table standard, so you can be pretty sure they are playing 2♥ over there. This is board 7 of the set, you had 2 excellent results so far, otherwise nothing special; maybe one plus position, and one slam bid by opps that your team mates are likely but not certain to push.
Do you try for the big swing with 3N?
