En route to winning the verystrong 1.999 open of Benasque in 1.999, Davor Komljenovic uncorked the following novelty against unsuspecting Agopov, scoring an easy victory...
Benasque organizers don't publish bulletins or have nothing to do with TWIC, so only in an article of Spanish Magazine JAQUE, IM Leontxo García analysed to detail the novelty... (his conclussion: very strong...)
Here is my own recollection of it...
(I also mentioned it to Tibor Karolyi, who said that it was possibly strong, but that he was no longer interested in engaging main line Botvinnik...)
