The Chess Thread

This looks very similar to the "poison pawn" variation that black can fall into when white is playing the London (just with the positions reversed). So I'll go out on a limb and say it's the same concept. While going up a pawn after capturing with the queen, it allows too much counterplay and development.

When sacrificing the bishop in that situation, there are a couple things to look for. Of course it's great to take away castling privileges but that on its own is not always a great thing. You need to have some development and be in a position to attack, either threating mate or winning back material. In this situation, white has not developed any pieces other than his queen. And with counterplay, he'll get stuck moving that queen around even more just to keep it safe, which allows a lot of development for black.

To get the best use of the analyzer, play it forward 10+ moves. When I've had the time, I've spent an hour or two analyzing the first 15-20 moves in games I've played and looking at different variations from common openings. It's really a great tool to have for new chess players these days.
I did some reading on the poison pawn this morning. That’s good stuff!
