sentences:  The fastest maximum break in a tournament was achieved during the World Championships on 21 April 1997, by Ronnie O'Sullivan against Mick Price in 5 minutes and 8 seconds.If an opponent fouls before any balls are potted, and leaves the player a free ball, the player can then nominate a colour and play it as a red for one point, then nominate a colour and pot it for its normal value.It is thus possible to score for 16 reds and blacks (16 * 8), plus the values of all the colours (27), resulting in a break of 155.
