What goes wrong in my head?

I would really appreciate some guidance here. My rapid rating is 1500 but the problem I have is a real beginnersproblem.

In this puzzle I play ... Rd1 threatening Rh1 in the next move. That is good.

White plays Kg3 to prevent and now I play ... Qf4+ thinking almost mate. The puzzles says it’s wrong and I check the engine afterwards to see why. Well, if Qf4+ white takes my queen with their rook... .

My question is how could this work in my head? I don’t see that the rook will take my queen in the next move. That is strange isn’t it?

Possibly kh3, preparing to give up the queen? Was it a one off blunder? In which case dont

MarkGrubb

Sorry. In which case let it go. Or do you find yourself making mistakes like this too frequently?

I do this too. I think it's a form of confirmation bias. Instead of looking for reasons why a candidate move is bad (what's the opponents best response?), the player with confirmation bias tends to look for the reasons why their move is good. This is exactly what you describe. Once you think "Qf4+ is almost mate", that move is marked as good and there is the tendency to stop looking further. This is also a type of quiescence error, where calculation is stopped before the variation quietens down. With Qf4+ there are still captures to be evaluated.

Finally, I have noticed a lack of flexibility in my own thinking. Once I decide mate is possible, I might fixate on that, and not consider other plans (such as Rh1, trapping the Queen).

I'm confused. Kg3 is not a legal move (the white queen is on g3).

If you play the linked puzzle, the opponent moves Qh3 at the start, so Kg3 is legal.

Yeah, I think it’s sort of fixation indeed. And yes Mark, I do this more often.

I am gonna think about your options Jugglin.

@JugglinDan+++ nice answer. You have to go looking for black sheep. Quiescence errors come up all the time in life. The common one is the rhetorical technique of having three things in a list. Whenever someone tries to convince you with a set of three it's a clear sign they are not confident with their case or their argument may lack objectivity, they've padded it out to three with rubbish, or they stopped at three because it sounded enough so there may be more there. Basically, be suspicious of 3s rather than convinced by them. Th
