## What is the shortest game to position with only 10 pieces with Double Edgemover?  

Nobody answered, so I show upper limit (21 moves):
 
Is this fast enought:
 
1.a4 h5 2.a5 h4 3.a6 h3 4.gxh3 bxa6 5.Rxa6 Rxh3 6.Na3 Nh6
7.Rxh6 Rxa3 8.Nh3 Na6 9.Rxa6 Rxh3 10.Rxa7 Rxh2 11.Bh3 Ba6
12.Rxa6 Rxh3 13.Rh6 Raa3 14.bxa3 Rxa3 15.Bxa3 gxh6 16.Rxh6 Qa8
17.Rh8 Qxa3 18.Rxf8+ Kxf8 19.Kf1 Qa1 20.Qe1 Qxe1+ 21.Kxe1 Ke8
