Thank you. I have been waiting for your take on this.
My take was different than both of your narratives more in the middle. Also even though there is no direct proof I have to wonder if Putin ordered the attack on the square and Yanukovych realizing that was a mistake fled. Putin realizing that he can't afford to give up the port facilities so he takes over the area he wants instead of waiting to see if he can continue to use the port facilities as if they were his own.
