Coming back from time to time to agree, @kotshmot @lfpatriotgames
When we have 3 candidate moves but lack the depth of vision or the necessary concepts to make an informed choice, then we have to make an arbitrary choice. I used hands of the clock that indicate the seconds to make a truly random lottery of this at times, but an arbitrary, willed choice is a matter of luck, then, as well.
Why? Well.. because I have no grounds for moving this or that way, and it is a matter of luck if my arbitrary choice will, on the following moves, disclose a combination or concept to me in time- or rather let my opponent present me with one.
Seeing something after playing earlier or later is not a matter of luck but of disposition and training, making the first one or two moves later turning out to be leading in the right direction is.
Luck in Chess:
Your opponent blundering or you accidentally making a very good move.
I wouldn't rely on it though, this isn't boxing... it'll take more than one lucky move to win a game.
Your opponent blundering in itself is just lack of skill leading to a bad outcome, not necessarily luck. You accidentally making a good move is luck indeed, in other words making a move that achieves something you werent aware of.
I have accidentally made good moves before. Lots of times. I've also accidentally made bad moves. When I think of luck in chess I think of the times I had no idea where to move. None. Like most people I narrow it down to about 5 seemingly reasonable choices. And because I have to move (I'll lose if I don't) I have to pick one of those 5. I can't flip a coin, because there aren't 5 sides to a coin. I can't close my eyes and move because I might make a really bad move by not watching. I've done Eeny Meeny Miny Moe before. And that works. So I'll make the choice based solely on something that has nothing to do with the position. Like the way the knight is facing, or we might be talking about The Crown, and move the queen.
If that's not luck I don't know what is.
Yeah you're totally correct here and described it well.
With an instance where a player accidentally plays a good move it's easy to tell that they were lucky.
With nearly every move played theres chance at play, but with blunders it's harder to argue the event was unlucky, because obviously lack of skill is the first determining factor.
