First, a set of deals where each player has 10 HCP. Can’t we all just get along? NO! Someone will find a way to bid. But can they play the hand?
This is the link to the PBN file with 32 deals.
This is the link to the LIN file with 32 deals.
Let’s not pretend to be all friendly. Here are deals designed to lead to interference of all kinds: overcalls with a long suit, 1NT overcalls, takeout doubles, negative doubles, cuebids. All of those things happen in random deals, of course, but most of these deals are guaranteed to lead to bidding mayhem. They are based on a script I like to call Bidding Melee V001, and there is even a handy guide to the purpose and structure of each deal if you don’t want to just wing it.
