Today I think that chess is 1% tactics and 99% luck

Nope that is totally wrong
If luck is more why wouldn't we be able to beat 2500+ in rapid cause we are less tactical
Wait then prove it by this
In the world play with every 2500+ fide and you won't even win a single game
Luck huh

Sacrifice not good enough

"Chess is and will always be a game of chance." Jan Hein Donner

There is of course luck in chess. But 99%? This would mean that Carlsen would win 1 game of 100 against me because of his superioir skill. And 99 because of he is a very lucky man. Vice versa that could be true.

If luck is not with you then it is almost impossible to win like the game I shown.
#2 Luck was with me in one game against a 2700+ and I won it being a piece down and just now I played a game where I was a piece up against a 2500+ but lost because luck was with my opponent .
#3 The sacrifice was enough please calculate properly.
#4 Everyone needs luck to be successful in life.
#5 If don't have any luck then you can't win.(at least I think so maybe I am wrong)

There is no luck in chess. "Luck" implies random chance, and there's nothing random in chess, other than maybe which colour you start. If you make mistakes, that's down to your skill. If your opponent makes mistakes, that's down to their skill. If you take advantage of those mistakes, or don't take advantage of them, that's your skill.

Nope luck doesnt matter, it depends on the skill

Everything doesn't depend on the skill luck is a vital thing.

I dont understand. En francais, s.v.p.
