Title: Queen corner round trip
ThreadText: # Queen corner round trip
  
  (Asked by: username_0 on 2024-01-13)
  
  In "The Ink War", Hendriks "complained" that in some game,
  during the Zukertort manouvre Q-e8-h8-a1-h1 the bQ didn't start at a8.
  
  Do you know a game with a Q corner round trip in this fashion
  (adjacent moves - order of corners is uninteresting), or with a rook?
  I'm very sure at least a game with nonadjacent visiting of all corners
  by a piece (maybe even a knight or king) exists, and in problem chess this
  4# theme has been shown even by myself (not even considering studies).

  > **Comments:**
  > **username_0**: Since I'm a Krabbe peruser, I should have remembered (to add insult to injury, I was even featured in #353 :-) In case someone digs up an adjacent Q example soon (Krabbe gives nonadjacent), the award goes to that person, otherwise I'll accept this one.  
  > **username_3**: Did Ernst really throw away the win after the ridiculous Re2+ instead of the obvious Kg5 and Lucena? Is the psychological effect of the roundabout trip of the black rook that strong?  
  > **username_2**: @username_3 No, it was a win. Forgot to include the 1-0.  
  > **username_3**: @RewanDemontay So 5.Re2+?? was never played I suppose, it is just an artefact of registering the moves (probably human-wise and not with an electronic board back in 1999). I think that move can safely be edited out.  
  > **username_2**: @username_3 What is the confusion here? White played Re2+, then Black resigned on their turn. As Krabbe put it: "This homerun was a swan song: 75...Ra1 76.Kh5 Ra8 77.g6 Rh8+ 78.Kg5 Rh1 79.Re2+ and Black resigned."  
  > **username_3**: Oh, I found only now the source of the confusion : In your answer you put 4.Kg4 (after which 4...Rh1 5.Re2?? Kf6 is a draw), while Krabbé's blog the correct move is given: 4.Kg5! Rh1 5.Re2 and Black's resignation is indeed forced.
