Isn't one of the first things you must do in aikido is to enter? Be sure to be there first or it's too late. Non resistance, keep a good state of mind not one on competition, If you see weakness in aikido then there is weakness in your aikido.
One of the best ways to learn how to deal with different kinds of attacks is to experiment with them in the dojo, ask a friend to train with you after class maybe? I do it everyday.
