Bf4 d4 17. Kd2 $1 Ne6 18. Be5+ Ng7 19. Bf4 $11 { This study is partially anticipated by Stavrietsky, 1st prize Babich & Olimpliev MT. 2017. That study shows 2 positional draws, with the white bishop on f4 and d2. The new study adds the same positional draw with Bc1. The transition between the three positional draws is engineered ingenuously through the a duel between the black d-pawn and the white bishop. The new study improves the economy by eliminating two officers, at the cost of 3 pawns. The fourth positional draw claimed by the author only changes the white king position and the fifth is in the introduction, both of which are less valuable. } 1/2-1/2

Ke5 $11 { After 14.Nc8 we have a perpetual check in which the white king must defend his central pawns and the black queen must keep checking to defend against the mate threat. The many captures in the first 13 moves reduce the impression. } 1/2-1/2
