82 ( +1 | -1 ) It's a system, in short*** Warning – I’m a patzer. You’ve been warned. ***
I play London System, pretty similar to Colle, or possibly a subset of Colle. The bottom line idea for both systems is that they are ‘systems’. So you play against almost anything. And you will get a mediocre, but pretty familiar opening every time.
In ‘system’ openings, there are no main continuation lines, as your opponents will decide what happens next, and at your current level, your opponents will just play everything imaginable. You will meet all kinds of ideas against your Colle.
If you decide to try Colle or London, just play it for a while and you will find your flow. When I play London, I try to block centre and go into King’s side attack early.
74 ( +1 | -1 ) I've tried itI've tried the version of the Colle that looks like this:
with plans of Ne5 and f4 and a kingside attack. Trading off your d-pawn is also nice since it opens up the dark square bishop. If black isn't careful, you get a very strong kingside attack, and sacrifing the bishop on h7 is normal.
However, I've read that this doesn't work so well against black kingside fianchettoes (like a KID). I think this is because of how black makes his kingside somewhat more immune to the bishop sac, but I'm not too sure. I just trust that it's true and play into more normal queen pawn games when I see ...g6 played.
