[D]2R5/8/8/8/1B4K1/8/p1p1p1p1/6kb w - -
And Chest with all 4 and some 5-piece EGTBs on a K7/600 with 350 MB hash
still needs 3.2 hours to verify the mate in 14.

PV: Bc5+ Kf1 Rf8+ Ke1 Bb4+ Kd1 Rd8+ Kc1 Ba3+ Kb1 Rb8+ Ka1 Bb2+ Kb1 Be5+ Kc1 Bf4+
Kd1 Rd8+ Ke1 Bg3+ Kf1 Rf8+ Kg1 Kh3 e1=Q Bh2#

Some more 5-piece EGTBs would have helped :-(

Cheers,
