[D]8/1P6/8/5k2/2K4p/7r/1r4p1/6R1 b - - 0 61

This position is from the game Tao-Deep Junior7 in the last WMCCC

Chest need some hours on p200 to see mate in 10(I used chest by the way that was
explained by paul some days ago

see http://www.icdchess.com/forums/1/message.shtml?191857

Solution:61...Rg3 62.Kd4 h3 63.Kd5 h2 64.b8Q Rxb8 65.Re1 Rd3+ 66.Kc4 h1Q 67.Re5+
Kxe5 68.Kxd3 Qd1+ 69.Kc3 Rb3+ 70.Kc4 Qc2#

In the game Deep Junior7 missed the right move(Rg3) but it did not help Tao that
resigned after Rxb7.

How much time does your program need to see mate in 10 with the full 5 piece
tablebases and without tablebases?
