...unless any of those letters appear in the answer - then you're locked into including them in subsequent guesses!

Even worse if your guess had them in the right location!

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.

Agreed.

I didn't want to spoil at the time, but yesterday you would have been unlucky with both these word choices!
