Grosgrain would combine with the g of a vertical word to horizontally cover two triple word squares plus clearing my tray. A gigantic score! But, the program rejected grosgrain as a word. I Googled it. There it was in all its splendor. I tried unsuccessfully to play it three or four times before I stamped my foot and used a lower scoring word.
G was formed in Escape Motions.
