Of course, the only perfect substitute for OTB is OTB! The way I play turn based chess, I don't use an analysis board, so the play feels like an OTB game without time constraints. But I am still calculating and visualizing everything by hand! Shadowknight's first point is of course true, but I don't think that keeps TBC a useful method of practice. After all, you are playing chess and thinking about your moves -- that's much of what practice is about!
As far as opening databases go, I usually only play a move I believe to make sense. That means if the database tells me (in the rare event that I use the database at all) a certain move scores well, although I will consider the move, I will not play it if I don't believe it makes sense, or can't find a consistent plan with it. There are two possible results of this: One, you are wrong, and end up playing an inferior plan; two, your less played move/plan is correct and you have perhaps found a novelty. Only in the former case do you become able to understand the motivation for a move you previously thought didn't make sense (a book move you reject). When you play an inferior plan, it's very noticeable as the position unfolds: you find that it is very hard to realize your objectives. That kind of learning might never happen if you reject your own move, assuming that the book move is correct. The point is, even if the book move is correct, you probably won't be able to have an effective follow-up without an understanding of why.
How do you use TBC to improve your OTB chess? Do you use any methods?
My OTB thinking process is awful and without system. I cannot create sound plans and end up playing hope chess. I was thinking about creating a checklist and use that for working my way through the TBC games.
My thoughts:
1) Use my checklist at every move
2) Use my opponents move to repeat my opening repertoire
3) Write down the reason for each move and expected reaction from my opponent and compare with computer AFTER the game.
Any other suggestions or is TBC waste of time regarding live OTB improvement?
