In this position, your opponent has exchanged one tile, indicating a strong rack, but also likely a rack that does not include a V or W, as very few exchange 1 racks contain those tiles.  Because of this, you are best off playing ASSaILs 8b (62), setting up the V and W hooks on the Triple Word Score.  Since you have first crack on those tiles, setting up this hook is a huge benefit for you.
