It wasn't a very long game but I had 0 inaccuracies, 0 mistakes and 0 blunders!

The London is the first opening I've learnt, I've been practicing it for a while now and I'm feeling like I'm getting good at it.

Maybe it's time to learn another opening. Any suggestions?

For black, between QGD and Slav/Semi-slav, which do you prefer and why? I am trying to understand what is appealing on both sides and why you make the tradeoff of potentially blocking in the your light square bishop. Personally, I respond with the Nimzo Indian as black, and when playing as white I hope for QGA or Catalan.

I'm assuming it's expecting Qxb5, Nxc7+ with a royal fork. But what's stopping c6 or Nc6 instead, keeping the black Queen in a position to protect c7?
