This particular game (if not the same exact opening move order) became a popular trap in English Opening when Abasov had defeated a GM as white in this situation. However after the move dxc6 , black should spot this suspicious attempt of rook sacrifice and definiteky should think of the possibility of c7 besides cxb7 and that to achieve c7-c8=Q there would be the deflection tactic along the semiopen a file . Its surprising that a player like Alireza missed that , but its chess , anything can happen here !!
exactly they dont show that,that is wrong, ,pragg is literally the one of the most inconsistent player if some people cover his games and expose(sorry but it my opinion)
