Assunto:  to IMPROVE vs of IMPROVING ?
 
Mensagem:  "Chess players find that playing against a computer is helpful to improve their skills, even though no chess-playing computer has yet won a championship."

POSSIBLE ERRORS:
A = TO IMPROVE
B = THEIR
C = EVEN THOUGH
D = WON
E = NO ERROR

I'd choose (E) but found this link that says (D).

Corrected Sentence:
Chess players find that playing against a computer is helpful in improving their skills, even though no chess-playing computer has yet won a championship.
The error in this sentence occurs at (A), where an improper idiom is used. The infinitive “to improve”  is used in combination with the verb phrase “is helpful,” where it would be more idiomatic to use the phrase “in improving.”
There is no error at (B). The plural possessive pronoun "their" is properly used to refer to the subject, "chess players."
There is no error at (C). The subordinating conjunction “even though” properly introduces the subordinate adverbial clause, “even though no chess-playing . . . championship.”
There is no error at (D). The word "won," the past participle of the verb "to win," combines with the word "has" to produce the appropriate verb tense.

Deep Blue (chess computer)
From Wikipedia, the free encyclopedia
Deep Blue was a chess-playing computer developed by IBM. On May 11, 1997, the machine, with human intervention between games, won the second six-game match against world champion Garry Kasparov, two to one, with three draws.[1] Kasparov accused IBM of cheating and demanded a rematch. IBM refused and retired Deep Blue.[2] Kasparov had beaten a previous version of Deep Blue in 1996.
