ArmInfo. In the autumn 2020, Moscow badly miscalculated the potential of Turkey and its President Recep Erdogan, Professor David Hovhannisyan said in an interview with  ArmInfo. 

"The scenario of the 44-day war was initially well thought out. And  it was the condition for Moscow's consent to Azerbaijan's aggression  against Artsakh. Under that scenario, the Azerbaijani army was  capturing the territories it actually captured – halting its advance  from time to time," Mr Hovhannisyan said. 

And the Russian scenario was developing until Erdogan intervened in  the Russian game, which brought about a change in the situation,  especially toward the end of the war. And Moscow had to resort to  rather radical ways of persuasion to prevent the theater of war  'going beyond the set bounds,' which resulted in Azerbaijan downing a  Russian helicopter gunship in Armenia's territory. 

And Moscow has now realized its miscalculations and is seeking to  remedy the resultant situation, which is a rather difficult task to  accomplish. And Moscow major miscalculation was thinking that the  Turkish president had nothing to do in that "from the first."  However, toward the end of the end of the war it was clear that, to  put it mildly, it was far from being the truth.

"Russia's current problems in Artsakh are being exacerbated by the  fact that Erdogan is to be reckoned with as Russia's ally, albeit one  of convenience, on the other platforms. And the obviously conflicting  strategic interests are not at all an obstacle to tactical  cooperation between Ankara and Moscow for common advantage, with each  of them interpreting this advantage in their own way. This  necessitates tactical agreements on various problems in different  places of the Greater Middle East," Mr Hovhannisyan said.
