IN 1960 Tal played....RXN...here.

Most of the engines I tested today do not find it........but

Fritz 8 finds it in 1 sec.

Junior 10 finds it in about 16 seconds.

How well does your engine perform here....???

1.5 seconds for Arasan (ply 9). This one looks ok, but many of Tal's sacrifices were unsound on close examination.

142 seconds for TogaII 3.1.2SE on my PPC.

1.4 seconds for ProDeo 1.6 BETA:

....many of Tal's sacrifices were unsound ...


Very true!

In fact, many of Paul Morphy's moves are just too hard for computers to find...!!....
