There are more captures in the original position and this is a very big difference. White pawns a,b,c cannot capture. black has no queen in your position the sides have less pieces. In the original position it is hard to calculate all the captures and in your position it is easy for computers. 100000 positions is easy to calculate for computers when 10000000000 is not easy. Uri
