Deep Fritz had no problem to solve 1-5 even on PIII450 in clearly less than 2 hours. It solves all the tests positionally. It can later see the tactics in number 2(in all the cases I gave it to finish at least 2 iterations after solving the test). In number 3 and number 4 it failed high in the last iteration without solving the fail high. Here is some analysis of Deep Fritz for positions 1-5 I know that the first problem that Deep fritz has problems with it is position number 6.
