You can put your size 3 monster anywhere, but if you have size 1 and higher, you have to retire them if you insist to call it. It is better if you use a size 3 monster with high defense in your center, and possibly accompanied by size 0 monsters, eg.(Dragon Kid, Ricky) to deal more damage but you should attack separately so the opponent cannot use a single spell to block your entire attack.
