Just when you are starting to get confidence and play reasonably well when along comes one of those days and for whatever reason out of 32 tournament hands you bid the correct contract about 26 times, missing out by 1 trick (an overtrick or 1 down) on around 18 of them , bidding totally the wrong contract 3 times costing 10+ IMPs, and totally missing an easy slam on 3 others (ie game vs slam). That gave me 1 4-rank, 2 5-ranks and a so so MP rank on another

Time for a break and not be discouraged

GIB does deal challenging hands

Practice makes perfect, they say

I'm more disillusioned missing out on stuff with a regular partner than the robots. They do get a bit of getting used to.

Practice makes tired
32 hands is a lot and towards the end your capacity to think straight will inevitably drop. Of course if an important tournament involves tens of hands then you have no choice, but it makes no sense to hammer yourself for hours in BBO on other days.
