I just did another session on it, and I realize that the same things that plague me when I play online carry over to this too. I'm not fond of playing on the internet because I find I miss a lot due to the 1 dimensional nature of the board. I lose something spacially without a regular chess board. When I look at the problems on the screen I tend not to see the position as clearly as I might if I were looking at it on the board.
The other issue that makes this especially challenging is that I only have 6 seconds before the opponent is going to make the move. I have 3 seconds to come up with the right move in order to get full credit. I don't really care about the rating so it isn't a big deal if I'm not making the move within 3 seconds. In a real game I would have more familiarity with the position because it would be progressing in real time. Here I'm being dropped into the position with no concept of what is occurring until I look at the board so it's hard to come up with an answer quickly. Also since I'm not part of the video game generation my mouse reflexes aren't so hot, so even if I do see the right move immediately the hand-eye thing just doesn't work quite as well as it used to when I was a ice hockey goalie in college.
I would be interested in other people's observations on using CTS as a training tool. Do you encounter some of the same issues that I have mentioned?
