Part Scores/Game Tries Set 25

This practice set covers common low level auctions that cause problems for people.  Is this a game hand or a part score hand?  Which is the best part score for us to play?  Should I keep the bidding alive?  Lots of good lessons to be learned from this practice set.

Note: There is no video for this set.  You get the hands to play here against the robots, or as a PBN file to bid and play them again in BBO or any bridge program, plus the notes and hand records.
