Want to beat all of the AI within 20 minutes of launching the game? Hate time travel? This is the guide for you!
How to Win
I'm a mediocre chess player (~1730 on lichess rapid, not accurately rated irl), and I love the idea of this game. My sarcasm in this guide is mainly due to my disappointment in the AI. I hope the multiplayer will be much better if I can find someone to play with. What excites me most about the game is the possibility of developing an engine of my own for it, to compete against the existing one. That said, I'll get to ripping on the AI, flaunting my wins, and showing you how to ruin your own challenge forever.
Bamboozling the AI
To absolutely bamboozle the AI, all you need to do is play a relatively aggressive opening by pushing your center pawns, bringing out knights, and bringing out bishops as the 'AI' lets you. The AI does not follow actual openings, so it is very easy for you to open your side of the board and attack while they sit around and do nothing.
Once you've developed some pieces, look to make any threats possible. The threats don't need to be sound, and you don't need to worry about alternate timelines, the past, or anything like that. The AI is completely stupid, and things like basic knight forks are invisible to it.
If you want to defeat the AI easily, simply never make a move you couldn't do in regular chess. If you do this, the AI will at some point make a single alternate timeline, but be unable to make any more. Once this happens, you're essentially just playing two different regular games against a really bad opponent.
Finishing Them Off
To win the game, you don't need to find any complicated checkmates. If you're playing aggressive and checking the king a bunch while capturing other pieces, you'll eventually mate it without even meaning to. This is because its movement squares are threatened by pieces that could travel through time, even though none of your pieces are actually going to travel through time, and you haven't even bothered to think about time travel.
If you're wondering what to do once you've absolutely trashed your fear of timelines, I can tell you that I personally plan to try some of the other game modes, especially the puzzles. I suspect anything against the AI will be about as easy as ever, but the multiplayer seems promising if it becomes active.
