according to Russian Grandmaster, ValdimirKaplan, this move has become quite popular and is uncharacteristic to this opening which the two combatants chose to play (Strive To Be Superior p. 175) Research reveals that in 1947, Russian Grandmaster Iser Kuperman in his match against M. Kogan responded with this move.

APCA Top Master player, Charles "Pecan" Thompson, reported that in 1977, V. Kaplan chose to play this variation in their tournament match, (Tournament Checkers, p. 171)
