	A very interesting position. I wonder which programs can find 43... Ra3 from
the adjourned position in a reasonable time (considering it was an adjournment).
	Have you read "The art of the middlegame" by Keres and Kotov? An excellent
book, which has a section devoted to adjournment analysis by Keres. The only
thing I do not like about it is that it is in descriptive notation, which is
really difficult to understand for non-English speakers, try to read Spanish
descriptive notation yourself and you will see what I mean (:
José.
