Ten frames fully drawn out are difficult to pull out with out rolling some bees which could include your queen. The best way to run nine frames is to push them towards the center and only allow the space between them to be with the edges of the frames touching. This gives you the right bee space and allows them to pull out the comb correctly. The gaps should be on the end frames and the brood box which can be easily scraped. If you place an already drawn out frame on the ends you usually don't even get that. Always have your frames tight against each other...always.
