It will be a gruelling fight for both sides. Small naval units have been battling each other since Kherson was captured. No successful amphibious landings at Kinburn Spit either. Best chance is that the Russians are trying to stabilise on several fronts and lack manpower.
This will be to Ukraine's advantage if they can sieze the initiative and push out of the bridgehead. Onto more stable land and use engineers to get some bridge going.
