His son Paul, also known as Povilas, was born in 1916. After the war and the USSR's annexation of the Baltic nations, Tautvaisas found himself a Displaced Person in Germany and eventually made his way to the United States where he finally settled in Chicago, Illinois. Tautvaisas was one of the Midwest’s strongest masters and his prominence in the Chicago area in the 1950s and 1960s earned him the nickname "The Old Fox". For many years Richard Verber and Tautavasis traded city championship titles. When Edmar Mednis published an early work on Tahl’s games, The Chess Psychologist Tal, many of the games were annotated by Tautavasis. He passed away in Chicago in November 1980 due to complications from alcoholism.
In the following game he defeats Erik Karklins, father of FM Andrew Karklins. Both players were long regular fixtures in the Chicago chess scene. Tautvaisas' last move resembles a chess puzzle, Black to play and mate.
