AI system AlphaGo on Tuesday afternoon. The winner of the five-game series has already

been decided. The AlphaGo team will give the one million

U.S. dollar prize money to charity after winning the first three matches.

However, Lee Se-dol took revenge in the fourth game on Sunday, adding extra intrigue to this

final game. Experts say today's game is a deal-breaker

for both sides. With another win,... Lee Se-dol could prove

to the world that his success in the fourth game was not a fluke , while a fourth victory

for AlphaGo would add more credence to the power of the AI system.

The 33-year old grandmaster from Korea has expressed his hope for another victory.

Lee has requested black pieces for the game and Google DeepMind's team has accepted the

request. The match begins at 1PM, Korea time, in Seoul

and will be broadcast live on the DeepMind channel on YouTube.
