LAUSANNE, Switzerland (AP) _ Viswanathan Anand kept alive his hopes of winning the FIDE World Chess Championship by drawing the fifth game in the finals Wednesday against defending champion Anatoly Karpov.

Karpov, 46, now leads by three points to two. Anand, 28, must win Thursday's sixth game if he is to force a tiebreaker contest Friday.

Wednesday's game, the most tense so far, took nearly five hours and was watched in silence by a packed audience at the Olympic Museum in this lakeside city.

Karpov, dressed in a dark suit with tie, and Anand in a maroon blazer and open-necked shirt, sat opposite each other in the dark auditorium.

They were flanked by the flags of their respective countries, Russia and India, as well as the banners of the game's ruling bodies and the host nation.

The winner gets a $1,373,000 prize and $768,000 goes to the runner-up.

Karpov won Friday's opening game and Anand won Saturday's game before the players drew Sunday and rested Monday. The Russian grandmaster upped the tension by winning the fourth game Tuesday.

Anand, 28, won the right to challenge Karpov, 46, for the world crown at a three-week qualifying tournament at Groningen in the Netherlands.

He beat Michael Adams of England in the semifinals.

Two of the world's top players, Vladimir Kramnik and Garry Kasparov, titleholder in the breakaway Professional Chess Association, didn't participate in the tournament.
