Be adaptable and don’t get locked into combinations because you can’t predict what your opponent is going to do. Always prepare for different possibilities. For example practice what you would do if in the middle of your combination they threw an attack, blocked what you were doing or stepped out of range. Once you can do the technique with your partner just standing there then have your partner try these or other variations. If need be stop and analyze what you should do and then practice it. Continue to do this trying as many possibilities as you can this way you become better prepared for anything that can happen.
