TRANSPOSITION
LATVIAN COUNTER-GAMBIT to PHILIDOR DEFENCE
White developed his king's bishop to QB4(c4) to exploit the "Italian" diagonal (a2-g7) and include control of Black's Q4(d5).
Black changes tactic, transposing into the Lopez Counter Gambit (a Philidor line dubious at master level) by pushing his QPawn out to Q3(d6). B-Alt.
