In this problem, it’s White to move and mate in two. What is the solution?


I would not normally answer this, but the real answer was deleted by its author for some reason, and is hidden. I also think that the original -3 for the question was more due to the original poster not being a native English speaker so I edited that too.

This is from the game Diaz Carias-Cordovil, 1966 Olympiad. Black resigned after 30.Bh6+, which is the first move of the solution. After Black’s forced Rxh6, White will play Qe5#.

    Even though this solution takes three moves to checkmate the black king I think it's good, since it forces a checkmate. However, for the sake of completeness, it is worth noting that there is a mate in two: 1.Bh6+!, Rxh6 2.Qe5#. – Scounged May 19 '18 at 10:55
  • @Scounged ,even your solution is right. – A.Shetye May 19 '18 at 15:34
  • Mate is possible in two moves only. – Bitthal Maheshwari May 26 at 1:58
  • The mate in two with Bh6+, Qe5# is pretty, but the more human (easier to see) mate would be this mate in three. In fact even 1. Qh7 leads to mate and is probably what chess players would first consider. – user1583209 May 26 at 10:02

Bh6+ Rxh6 forced and Qe5 is then checkmate

  • I didn't downvote your answer, but it's just a repeat of what is said in this answer, which includes a replayer for visualizing the moves. It doesn't really add any value IMHO. – Glorfindel Jun 1 at 7:17
  • I saw one incorrect answer as it used 3 moves to checkmate, and one that went through a whole game to get to the position which was not part of the question, and then had the mate in 2 as an aside. Mine is a simple answer to the question. – CashCow Jun 1 at 9:32
  • Fair enough ... the solution is mentioned above the diagram there, and with a small edit I was able to have the diagram start from the position in the question. – Glorfindel Jun 1 at 9:35
