I analyzed the game with several engines, most have serious blunders in their
thinking lines. For example, in almost all the lines you see that black plays
...dxc5, that move is a severe blunder in the KID formation, in other words it
is _always_ wrong (even if it's right :)
Even before Rf2 white was technically lost. That move only made the victory
easier for black. White should have played cxd6 cxd6 Nb6 earlier, followed by
Nxc8 even if black leaves it a8 rook en price!!! In such positions the c8 bishop
is at least as strong as a rook. When white removes the c8 bishop, black's
attack, formidable as it might seem, loses all its venom.
When I play white against KID's Mar del Plata variation, I try to remove the c8
bishop at all costs, even at the cost of sacrificing a rook. Without that piece
black has almost no chance.
