So, if you have only one legal move, you still want to take your time?
I guess that's up to you, although I'd never understand that.
A forced series of moves, usually lead to a critical position. I like to be thinking about critical positions several days in advance of their arrival on the board. Another reason I would wait to make an obvious moves is that I am usually playing about 12-15 CC games. If I instantly play all the obvious moves, it will create a log jam of games that all have critical positions. I prefer to spread my critical decisions out over a period of time. Thirdly if you quickly play the opening moves of a game, it is very hard to get your head in the game when you reach a point where you have to start making critical decisions. Finally if you look at Capablanca's game, you will discover a lot of times that his opponent thought Capablanca had an obvious recapture, and Capablanca found a decisive zwischenzug.
These are very interesting arguments for why you prefer not to have your opponent move rapidly. I think I can understand and appreciate them, and they are possibly the most lucid ones I've seen so far in this thread :-) I don't see how you can improve your situation and gain more analysis time, though, if your opponent simply choses to respond rapidly by hand.
You mention seeing a position days in advance -- out of curiosity, how much time do you actually spend on planning and moving in your games? I have a tendency to play fairly quickly (couple of minutes) once I see the new position, although I realize I should probably extend this. Does a player like youself (400 pts higher than me) actually spend an hour scheming and plotting at many places in a game? What's the most or typical time you sink into a good, evenly matched, game?
If you are the kind of person who is predisposed to see everything as some kind of personal slight against you, then perhaps conditional moves on a chess website are the least of your worries.
Again with the cheap psychological card? Isnt it enough that we are not magnanimous as you sages are, you have to bring it up in every other response too?
