Working with CTS has given a whole new meaning to the expression "a tempo".
CTS shows that the slightest hesitation costs you already a few seconds.
To get the full reward at CTS you have to give the total solution within 3 seconds.
That is really short.
Below you see a typical situation.
Black to move.
The last move of white was Ne5, attacking the black queen.
The first thing that came to mind was 1. ... Nxe5 but that loses the queen.
Then I saw 1. ... axb5, winning a piece.
I did the move, then came a shock: 2. Qa8+
I hadn't seen this check. But with 2. ... Kc7 blacks problems are solved.
Total time used: 6.2 seconds.
About 3 seconds per move.
That I could solve the check was pure luck, I hadn't seen it coming.
That is an extra on CTS what you don't have OTB, there is always a good solution somewhere.
The question arises if it is actually possible to see the whole line within 3 seconds.
The details of the problem revealed that there were only 6 persons out of 60 who were able to solve the problem in 3 seconds or less.
Those 6 persons had an average rating of 1774, that is 250 points higher than mine.
Working with CTS is as if I have to learn chess again.
But now a tempo.
I have to learn all the one-movers a tempo first.
Before that, it is impossible to learn the more-movers.
Even with a problem like above I see actually two seperate one-movers and not a two-mover.
So there is a long way to go.
The fact that there are now 4 masters playing at CTS and that they all have a high rating is enough prove for me that I'm on the right track. They all are extremely fast in more-movers.
The most important thing is to realize how bad we are in one-movers.
Doing 300 - 400 problems a day should do the job to adress this problem.
