When you make 147, It tells that you are in full form and a red signal for your opponent, Stephen Hendry made his 11th 147 and 3rd at Crucible, and then he announces his retirement, I think he could have played for another 2/3 years, but he has some standard he had raised the standard of snooker when he came into this professional circuit, so you could expect from him to announce retirement when he was still able to play snooker at its best, for example, 11th 147. He is LEGEND and will remain, whatever he had achieved in his carrier one can only dream of it. He was looking very confident the old Hendry of 90s in the start of this Championship, You can say, it was one of his bad day which had to happened in Quarter Finals of World Snooker Championship 2012 against Stephen Maguire. I grew up watching his videos, then trying to copy his stance, always visualize his style of playing whenever i was playing or holding the cue, and it had helped me alot. I would like to wish him good luck for the rest of his life. Snooker won't be same without you and you will be missed badly Stephen Hendry. I ran out of words right now cause there are no such words which can do justice with you. Im happy and sad at same time too, happy cause of his brave decision and sad cause won't see the classic 147s anymore :/
