"I would have, could have, should have hit her" That's pretty funny that as soon as she had an opening she went for it and kicked your butt. That my friend is the difference between black belt and not black belt. A black belt will always seize the opportunity. Why would myou want to hit somebody in the chest? This is not a good target, you'll never K/O somebody there. She nailed you in the SOLAR PLEXUS not the "soft spot" you should learn a little about the solar plexus this is a vital target which should be taught at white belt level. Well good luck to you and dont be afraid to hit a girl during kumite because if you dont hit them, they'll darn well nail you!
