Ion Gudju was a Romanian chess player and problem composer, born in 1897 and passing away in 1988. He was a significant figure in Romanian chess, particularly active in the early to mid-20th century. Gudju was known for his contributions to chess as both a player and a problemist, creating and solving chess problems, as well as competing in various national and international tournaments. He played a key role in promoting chess in Romania and was involved in organizing chess activities in the country.

Specific details about Ion Gudju’s favorite openings or play style are not extensively documented. However, given his era and involvement in chess problem composition, he likely had a deep understanding of both tactical and strategic elements of the game. Players of his time often favored classical openings that allowed for rich, strategic play. Gudju may have favored openings such as:

• Ruy López (Spanish Opening): Known for deep strategic play.
• Queen’s Gambit Declined: A solid opening that offers strategic complexity and control.
• Sicilian Defense: Popular for its dynamic and counter-attacking potential.

These openings were common among strong players in the early to mid-20th century.
