I am struggling. I have extra words "Go " "bishop" "queen" amongst others but cant make sense of it. The 3 might indicate a board game theme, Go, which I dont know anything about, or chess.
I also have gaps where I have entered 2 letters in a cell but the pre-amble does not refer to these. In every case the number in brackets equates to the number of cells in the grid, not the number used for entry .
There is no reference to Chambers so the whole thing is baffling. Is it April Fools Day - I thought that was next week.
