N/S +150
13

Here's the hand that could be followed with quite colorful results in a human-only game. In a strong field, the mode should be +140 to EW after 1N-2-2N-3, followed by some +100, some -50 and perhaps a few -110. It's even easier for EW to be in a  partial after 1 opening although in this case NS hands are more difficult to read and N is on lead (S is endpleyed at trick one), so opening 1 may bring a reward of -110. Before reading further you may entertain yourself by finding a combination of defense and play to 11 tricks after the bidding on display.

Now let me describe the results from a BBO 55% tourney, where the crowd is usually better than at average club game. All 11 players opened 1N and bots deemed W hand unworthy of 2. Two humans bid silly 3N after bot transfer to s for -300 and 5%. Those who played in 3 received identical bottish defense in first four tricks you may see by clicking on the hand diagram. Five players forgot to ruff a  at trick five to score 110 for 40%. Three others who made this play didn't see a reason to draw the remaining trumps while in dummy to end up with 130 and 80%. Finally, it had looked to me that a delayed Bath coup could be on, and it did. Note that the bottish defense was clearly necessary for this ending, which is a reason playing against bots is good to hone up one's card play.
