i tried Bishop G2 to D5.
Black queen either has to take the white bishop or move along the 7 file. in either case checkmate can still be got in the next move.
if the queen takes the bishop, then White queen to either E7 or G7. (queen cant block.)
if it chooses to run along the 7 file then white queen takes black bishop except if the queen moves onto D7.
