I expect someone is void in diamonds and therefore how many defensive tricks does my partner have? I have 2... my partner should have 1 outside of diamonds for his bid. Maybe he has 2, tough to say. At IMPs I just fly 5d. At MPs I might go slower and see what happens.
fwiw... I feel the same way... I alter my play in robot tournaments to expect finesses to be off. I find that to be more annoying than bad trump breaks which seem to be more randomly distributed.
