I prefer closed positions. I play a lot of quick, one minute, games here on Live Chess, and I have a 1500+ rating in it. The reason I do pretty well at them is I that I strive for closed positions. Albeit, most of my wins are gained on time instead of by checkmate, most quick players don't realize that, in a closed game, speed counts more than accurate moves.
I've been trying to specialize in the Bird Opening (1. f4) and I believe I've gotten pretty good with it. I try to do the "Real" Bird instead of, for example, the Polar Bear Bird version. The Real Bird consists of 1. f4, 2. Nf3 and fianchettoing (sp) on both sides right away, not just the king side. Doing this often leads to pretty good play on the flanks, which is what is needed in closed games.
I would like to start a debate about which positions are better: open or closed. So feel free to post your comments about which are better, and why do you like that kinds of positions? ( and if you feel any advanteges on playing that way, that kinds of positions).
Sincerely: Percyval
