Seems like the best strategy is to choose words with repeat letters. For example, two great first choices would be LOLLY and SASSY. That's two empty cells that can't be used to guess.
I think no. This one's actually got a lot of depth to it. SASSY and LOLLY use up Y which is critical to forming 5 letter words. S is pretty good too. Preserving your vowels seems to be an important concept. You want to minimize the usage of them. But if you get a single yellow value you can dance around it safely. Or if you get a single green of it and no blacks, you can go for a word using two of that vowel which hopefully doesn't prove to be correct.
WHIZZ seems like it could be a very strong opening move.
Well, yes, but you're playing the odds. Sure, make the wrong choice and you can lose fast but I'm guessing, statistically, repeated less common letters is the best overall approach over time.
Those are decent words for antiwordle (my usual starting words for that are ESSES, MAMMA, COCCO), but this game is significantly stricter than antiwordle.
A decent strategy for guaranteeing that you can win is:
1. Play good Wordle moves (SOARE, RAISE, CRANE, SLANT/PRICE/DOUGH/BALMY[1], HANDY/SWIFT/GLOVE/CRUMP[2]) so that you can determine what the secret is.
2. Undo each of those so you have no restrictions about what you can play.
3. Figure out a 6-word sequence that you'll be able to play that doesn't include the answer. (I started out with some of those double-letter words, another word that used the remaining vowels, then worked backwards from the end with progressively fewer green letters.)
Though apparently if you type in the secret word, you can't undo that, so it may be valuable to re-do the analysis from the links but looking for words that can't possibly be the answer.
Yeah, I guess you can prepare a set of strong (well... weak?) single-vowel words like XYLYL, URUBU, etc. for other vowels, plus the trumps of GRRRL and PHPHT and play these in sequence, undoing if you get a colored square too soon.
WHIZZ seems like it could be a very strong opening move.
VEXED looks pretty promising too.
