I played in a 12-game Scrabble tournament on Saturday (twelve games in a single day!) and this was one of my starting racks late in the day. I didn't have my phone on me at the start, so I took tiles at the end of the game before they were organised into squares (to show that all the tiles are present) to arrange them.

This word (with the blank being D, R or S) is not a valid word in Scrabble. I passed to see what my opponent would do, and used her I to play GOOPIEST (which is valid; she challenged it).
