Actually, robots make a tremendous amount of mistakes. They are extremely bad in competitive auctions especially at the four-level or higher. They have very poor judgement in evaluating hands- --,xx,AKQJ10xxx,xxx, Kx, xx, AKxxxxx,xx and x,Qxx,KJxxxx,QJx are all 3D "invites" over a 1S opening to them. And they often make gross mistakes in the early stages of defense, they rarely duck Aces and almost never duck Kings, they tend to cover an honor with an honor too readily. They are quite competent declarers though, and they are excellent defenders once the distribution is rather obvious. They also make a lot of interesting falsecards, and their habit of discarding top-down from equals and leading second highest (after the opening lead) with all types of holdings can be confusing if you are not used to counting the hand. I like winning masterpoints, and I play a lot against the robots as it's one of the fastest ways to do so. It's not cheap, but it's cheaper than playing in FTF games--and you don't risk COVID. You need to get used to how they play, you need to read the explanations of what their bids mean almost *every* time as they often do not conform with what a standard or 2/1 player would expect, especially in competitive auctions. And you need to learn to take the good with the bad--you will get fixed by them, but they will fix themselves even more often if you let them.
