This was, in a way, a desperate move, and only with quite some luck I got away with it (the opponent missing the right move, and the 50% chance of my king being in b2) - but that's how quantum tactics work.

Here's an interesting case of heavy entanglement, resolved in an instant after a single move. Notice how all copies of the queen disappear, but also all rooks get massively re-adjusted as well as the pawns at e4 and e5.

While it's fun and all, they also solve the problem of never finding an opponent to play against. Now you know when to arrive to have an opponent.

Carlsen and Nakamura fans should also be happy about a potential rating decay rule (which is coming as per FIDE officals).
They will hopefully get to see their heroes compete in even more classical chess events!

Chess desperately needs some form of rating decay for a multitude of reasons: 1: Top players can maintain their ranking with very few games per year, preventing up and coming players from challenging them. Making it easier for them to blacklist players like myself. 2: Rating decay would challenge the anti meritocratic invitational round robin system. Most top events like GCT, Wijk, Norway Chess, have 0 open qualifiers. Any serious sport gives fair opportunities to top events, instead of using a subjective invitational system. 3: The top 2 players who wield the most influence would not benefit from any change and I’m sure their chess mafia counterparts would do everything they could to maintain their “narrative”. A 40-60 per year minimum games in TOP tournaments(Mickey mouse doesn’t count) that all MUST have open qualifiers would dramatically change the chess ecosystem. I firmly believe that FIDE should mandate every event that wants to count for circuit points have at least one open qualifier. While the addition of many new events and prize money has been extremely positive for chess, the classical rating system invitational system desperately needs reform.

You have many other options though. The most fun option though is to choose c1 as the second target square, and castle to both sides at once. You end up with two copies of the king, safely stowed away and protected on both sides. With a degree of probability, that is.

This is not too obvious, but once the move to g1 is made, f1 is occupied with the rook, and the king wouldn't be able to move there. Same on the other side.

This goes both ways, too. If at a later point we establish that the queen at h5 does exist, the bishop at e2 will be shown to not exist, which will then show that the one at c4 does exist, and one single move of that queen will change the board quite a lot.
English
This, too, is a backward entanglement - if this bishop actually does sit at e2, the queen will find it never made the jump, and isn't where it appears to be.
