CT offers many solving modes. I use "Standard" where problems are untimed. CT presents me with problems that range from slightly higher to several hundred below my own current rating. The Chess.com TT has only one rated solving mode. I am not presented with problems 200 points below my present rating. Some problems must be solved quickly, while others allow several minutes. The score is determined by solving time and number of correct moves. Some problems require a single move, while others may require nine or more for the solution to be considered correct.
My Monday morning session with Chess.com's Tactics Trainer was frustrating. I attempted fourteen problems, correctly solving half. The electronic environment seems to have undue influence on my board vision. When I do TT on my iPad, the Board is a good size and stable. When I do it on my notebook computer, part of the board is obscure at the bottom of the screen until I adjust with the browser scroll feature. I must make this adjustment at the beginning of each new problem. In contrast, at Chess Tempo, I need only make such an adjustment once at the start of each session.
My longest training session was Tuesday with Chess Tempo (49 problems), but I continued to use several resources. Most days, I solve a few tactics problems first thing in the morning after making coffee, or even while it steeps in the Bodum Press. The convenience of several excellent chess apps for the iPad makes it possible to solve a few chess problems any time that I am in a position of waiting for something else, or during television commercial breaks for my favorite crime dramas (NCIS, Criminal Minds).
On Saturday, my stubbornness led to an initial struggle with psychological nonsense giving way to a marathon session that seemed counterproductive.
