The Russians captured Azov and Taganrog in a war with Turkey that ended in 1700. Then they decimated the Swedish army at Poltava in 1709, thereby crippling their main enemy, and freeing the bulk of their forces for action against any enemy, including Turkey.
The Russians were "on a roll" by 1710. How and why would they lose Azov and Taganrog to Turkey so soon after winning such victories? Or did these victories make them overconfident?
Conversely, if the Turks won, it didn't seem to have done Sweden or its King, Charles XII, any good (given the ending of that war), even though they were allies of Turkey. Why is that?
