This is from the daily free MPs tournament. North was a Robot and chose to bid 6♥ at this time. I (South) held:
6♥+1 scored 53.8% whereas 7♥= was 90.8%
As an afterthought, I felt that all deals in the Robot North's sample (if it does sampling at this stage) should indicate 7♥ is the logical/correct bid. I'm asking in earnest whether sampling works at different stages of bidding and (if so) why North would not directly bid the grand slam.
