I am not natural talent, I've just doing that for days now (3 times on a daily basis for two weeks )😞

Final Time: 36.52


I did do similar exercise for weeks about a year ago though...

edit: 34s

17.36s Let's see if I can break the record... I'll try this evening... probably unlikely... 3 straight times 18 s.

But I have played blindfold before; that helps. 🙂

Certain squares I can get immediately - pretty much all the squares except e1, e8, g1, a7, g6 and a few others.

Now 14.81 s Good enough for me...

That is very impressive. So you know all the squares by odd or even system or you just know them all separate ?

I don't know them by any system. I think e8 and immediately somehow "see" the board in my head and link it to a light square. But for many squares I just know the color of the square I think because of blindfold chess - I can think of moves and recreate positions reasonably well not looking at the board.

Although many players don't see the board in their head, what they actually see is some sort of schema of related squares.

14.28 s now. 😵 Ok, I'm going to finish my homework and memorize the few squares I don't quite get and crush this thing.

Odds on a player such as Korch breaks 17 s.

62.88

I rule!

If you know that "well... odd numbers on a c e g are white and even numbers on b d f h are black," how does this help your visualization, becdause you're not visualizing, you're using a furmula. Just a question.

Cool link! Thanks for sharing. After several tries and using no tricks, I'm getting exactly 21.

Additionally using that technique is also going to slow you down.

Down to 13.84 s. Confident I can break it but keep hitting 15 s. Not using any tricks although I already have most of the squares practically memorized - again playing blindfold chess helps. A lot of GM's (Ivanchuk, Anand, etc.) play without looking at the board very much. Ivanchuk is particularly noted for this technique.

Why aren't you on the high score board...?

Matrixobi is me. Now hitting consistently at 14.7... to hit under 14 s, you cannot hesitate. 🙂 My advice: be consistent, don't rush and the time will come.

... I tried just spamming only one colour.
Statisticly I'll eventually HAVE to get one thats 25 lights, right?

Best is 7 in a row so far

Assuming randomization, the chance of getting one that is 25 lights is one chance in 33,554,432. (In the US we use commas to signify three places. )

For 7 in a row, 1 chance in 128.

To get a time of 12.34 s requires getting each one in .4936 s. Consider that reaction time is approximately .1 s at best (thinking about 100m dash runners here) .

I've got it under 18s now using the odd/even technique but I admit it's probably not doing much for my visualisation.

I got 16.55 and I'm in the top 10. Now. the limitation is mostly physical. It's hard for me to use the trackpad and click any faster.

I'll make a few more attempts tomorrow so that I get into the top 5. I think this exercise won't help my visualization anymore after that.

After some tries I made 33.81

but I think that using the even/odds trick it's just a math test, not a visualization one
