I don't typically play robot tournaments on BBO because:
(1) "best hand for South" is too artificial for me
(2) Having a robot for a partner somehow makes my play less serious -- there is no one to let down!
But I did play a robot tourney yesterday, finishing barely in the money with 54% and both these aspects were on full display, ironically on the best and worst hands of the set.
My best result (worth 81%) was when I passed out a 13 point hand in fourth seat. Totally artificial.
The worst hand of the set was this one where I forgot that LHO had bid clubs. Partner happily put me in 4S which got doubled and went down 3. 4H, of course, should go down. Surprisingly, -500 was worth 38% because some five players defended in such a way that 4H made.
Forgetting what the opponents bid never happens when I have a human partner -- this is strictly behavior that happens when playing with a robot!
