Bisides chess, I love music. (Hello Nezha, how is you guitar play?) Staccato, litterally translated, means «not sticky». In my last days on CTS I got an idea why I lose so much time and rating, and why I fail in so many problems. It is sticky thinking. I think I must explain this further.
Example: I see a King in trouble. Of course I look for a mate. It may be a near-mate, and I try this and that and again and again. Seconds pass. So I feel urged to move. I move. Bad Luck! You've failed to solve problem ... Your new rating is ... It turns out that the King can escape mate. The real issue is a simple Queen Fork. This is what I call sticky thinking. My thoughts are stuck to a mate fantasy where there is no mate. This fantasy prevents me from seeing the fork.
I also get an idea how all these titled tacticians on top can get a rating of 1800+ or even 1900+ on CTS. They just see in a fraction of a second that there is no mate, so they are free to look for more patterns, and, whoops, they click the fork in less than 3 seconds and get their points.
But staccato thinking is not sufficient to reach the CTS peak. You also must be able to collect all important patterns in the 6 seconds before the problem makes its move. Then you can use the 3 seconds to decide which pattern is important.
When I am tired, sometimes, I even have difficulties to figure out which King is mine. Once I tried to check my own King, haha. Or I stare at the board with tunnel vision and do not see that my King is in check. When I look at all this, it is completely clear why I am below 1500 and they are above 1900. To explain this is one story, easily told. To change it and join the top is quite another story.
