Deep Junior 8.ZX doesn't make these three horible moves, even on
my "slow" P-IV 1500 MHz, with 64 MiB hash tables. This of course
doesn't mean that ZX is better from simple Junior, but in my
opinion DJ8.ZX indeed plays better chess from DJ8, from the 30-40 games
i have seen so far by both.

Here plays the right move and not Kd2? in 10 seconds:
[D]r1b1kb1r/pp1n3p/2p2P2/3p2p1/8/2NBP1P1/PqP2PP1/R2QK1NR w KQkq - 0 1
