I believe Karpov is closely associated with Putin while Kasparov is involved with anti-Putin protest so I doubt they meet for tea now and then.
I do remember a year or so ago reading that Karpov came to the jail to release Kasparov after he was detained for organising an anti-government protest though.
Does anyone know if these two great champions have "made peace" with one another? Their rivalry was a bitter one, & then Karpov visited Kasparov when Garry was imprisoned for his political activities. Kasparov then stood along side Karpov when Karpov was running for Fide President. Have they warmed up to one another? Very curious. Reminds me of when Spassky & Korchnoi had bad blood during one of their candidate matches, then years later, joined together for a match & seemed to get along well. I, for one, hope that the two K's are at least on friendly terms for he rest of their careers. Thanks for any info or thoughts!
