SAN JOSE (Reuters) - Costa Ricans vote on Sunday for a new president in what looks primed to be a close contest between a former leader promising continuity and a pugnacious economist who could pull the country down an anti-establishment path.

Former World Bank official Rodrigo Chaves has shaken up the race in one of Latin America's most politically stable countries after confounding expectations to place runner-up in a first round of voting in February.
