Dagestani born tycoon Suleiman Kerimov watches a soccer match between Anzhi and CSKA in Makhachkala December 2, 2012. Kerimov built his multi-billion-dollar fortune with an appetite for risk, debt and excellent political connections. Yet there are signs that the secretive mining tycoon has used up his credit with President Vladimir Putin, who exerts a tight grip over the strategic natural resources that fuel Russia's $2 trillion economy. The 47-year-old from Dagestan has found himself in a tight spot after his company Uralkali pulled out of a potash cartel with Belarus in July, upsetting the market and infuriating a close - if difficult - ex-Soviet ally.
