As for the queen and rook battery, the pieces are positioned in such a way that the queen must make the first move. Generally speaking, I think it’s better for the rook to move first. Although it's risky for the queen to attack first, it can also create a checkmate threat.
I'm not sure if it's commonly referred to as “Queen Head.” In fact, it was the first time I'd ever heard the term. How about in your country?
I once found myself in a similar position during a game on OTB. My opponent said something like, “This is a ‘Queen Head,’ so it’s not good.” The term “Queen Head” really stuck with me, and I think it’s worth identifying as a chunk.
Hi kota Okishima I haven't heard this term. I don't have any idea now. I should study about it.
Thank you for your reply. I searched for this on Google and other sites, but couldn’t find anything relevant. I think it’s important for this service to cover these kinds of unique patterns, so I plan to publish this chunk later.
