It was an odd one, but after two plays, I had two letters locked in. And I also knew, from those two plays, which other, more common letters
weren't going to work/be available, so I thought about it for a bit - considering a few letters I typically don't, and with a bit of time/thinking/"what if" between move #2 and #3 - before making my third entry, the one I felt most confident about. To my delight, all the tiles flipped green and the little onscreen thing said "impressive".
I'm on a roll. I expect it to fall apart any day...17/6, etc.
