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.
