ottoman lower Volga river after 1711 ?

what if ottoman killed peter the great in Prut river campaign and then allied with Sweden attack Russia. could they capture Volgograd? . peter the great was very careful not wage two front war. he waged his war on the ottoman as coalition warfare. only in 1768 did Russia attacked the ottoman without Hapsburg alliance.
 
By 1711, almost ASB-the lower Volga is too far away and too Russian. Even if they were somehow able to occupy it they'd have to spend enormous resources to occupy it against Russian attempts at reconquest aided by the local population.
 
if death of peter the great lead to civil war. than ottoman can capture don river to Stalingrad. than ottoman and sweden can block Russian access to sea . russia cant fight two front war then in 1711
