White gives Black an isolated Queen's pawn.
Gheorghiu thought Black already had a sizable edge.
Placing the Rooks at e8 and d8 is best in these positions.
The beginning of a maneuver intended to put pressure on Black's pawn with Qb2 and Bc5 and possibly e3 if the Black Queen remains at d7. The problem, of course, is that this plan is slow and allows Black to attack. White must play 19. e3! d3! (19... dxe3?? 20. Qc3+-) 20. Ne1 and hope that he can win the d-pawn.
27... Qf1+ and Black will force mate. 0-1
