I mean, It's only the conclusion of this game which is nice, but against a
computer, Spassky would have been lost before reaching the position before h4.
Larsen should have taken advantage of Spassky's wrecklesness.
OR, ARE Spassky's 10th and/or 11th move(s) OK according to top computer analysis
of now? I haven't checked at higher than programs Hiarcs 7.0 and Fritz 5.32.
(together with "moving along" analysis).
