The chess thing did involve some serious conditions that weakened stockfish, but as I understand it stockfish was still running at a level where it would have beaten any human being. Chess programs are way, way beyond humans at this point. Improving a chess engine at this point is an engineering challenge. As a resource for humans to improve at chess the ceiling has already been hit.
The poker bot thing is interesting. The main use of a bot to this point in most of the games is that it allows for insane volume, and if the side has a substantial bonus program, a bot can be useful. The downside is that using a bot isn't that awfully hard to detect and it will result in the site taking your money and banning you. That is assuming the site gives a shit. Bots pay rake.
Computers have solved limit holdem and do really well at heads up no-limit, but as far as I know not all that awesome at anything else. Well enough to do OK in the smaller games, but it isn't like chess where you get blown off the board. Really, the only functional difference between a reasonably skilled human that plays 24 tables and a bot is that one of them is made out of meat.
Unlike chess, poker is a game of limited information, and probably more important, a game where a, and I hate this phrase, "game theory optimal" approach is usually less effective than an exploitative strategy in a multiplayer game with weak players in it.
The idea of GTO is a balanced strategy that, even if the opponents know what it is, they can't exploit it. An exploitative player deviates from the balanced strategy when doing so creates a greater advantage over a specific opponent. Since that opponent has a finite amount of chips to lose (especially in a tournament), being exploitative can be a great advantage.
Of course, one can exploit the exploiter, which is why doing that stuff is insanely complicated. Moreso in some tournament conditions where the value of the chips is itself variable.
I'm sure at some point a computer will do all this better than any human. I wasn't so sure it would be anytime soon, but if this is a totally different approach, maybe sooner than I thought.
