Ottomans have zero chance of naval superiority. The best they can do is keep the British away from the coasts with Coastal batteries and mines and try to keep the Russian Fleet in Sevastopol if possible. The Ottomans certainly could have achieved better results. If Enver has patience and remained defensive in the East he might have had a better chance in the offensive on Russian Armenia later in the war. The best case scenario is a German victory in the West by 1915/1916 without a disastrous Sarikamish Campaign.
