Several maxDTx positions arise from an underpromotion. Helmut Conrady found
quite a few ages ago:
[D] 1n6/3P4/8/8/1K6/7B/8/k7 w
1. d8N!
[D] k7/3P4/K7/8/3n4/8/3N4/8 b
1. ... Nc6 2.Kb6 Nb8 3.d8B!
[D] 1k1K4/4P1N1/8/8/8/6q1/8/8 w
1. e8N is the only move avoiding mate in 1
[D] 8/1n3P2/8/8/3K2P1/8/k7/8 b
1. ... Nd8 2. f8N, the only fork-avoiding promo, a theme seen before
[D] 8/1P6/8/k7/1P6/6K1/8/6b1 b
1. ... Ka6 2.b8R! {or 2.b8Q?? Bh2 3.Kxh2=}
