Okay sure fine I will scrabblepost too
I also play the bots on woogles and as of a couple months ago I've graduated from beating up BetterBot using void challenge (where the site tells you if the word you're playing is invalid, doesn't let you play it, and lets you try something else instead) to getting absolutely pummeled by it using double challenge (if I play a word that is no good, it's challenged off and I lose the full turn). This REALLY tests your dictionary knowledge as you can't just go "uhhhh maybe this?" you have to KNOW your words. It's tough because I haven't really thoroughly studied but it's also more fun once you have a decent knowledge base to actually test it.
Attaching my best game since doing the switch here, but know this is a severe outlier
haha among us
