Why is Qg4-Qe6 the correct move here?

Given this board setup:

``````6k1/1p3rpp/1q1p4/p2Pp3/P5Q1/1P3PP1/2R3KP/8 w - - 3 13
``````

Puzzle states: White to move, find the best move. The puzzle solution says Qg4-e6 and the rationale is that Rc2-c8+ cannot be stopped. It seems to me, and some computer programs agree, that going directly for Rc2-c8+ is better because it forces a response of Qb6-d8 followed by Rc8xd8+ Rf7-f8, Qg4-e6+ Kg8-h8, Rd8xf8#. I am no master, I barely can call myself novice. So why is the solution saying that Qg4-e6 is better?

• I prefer Rc8 as it is more forcing. I don't see the advantage to `1. Qe6` Nov 8, 2015 at 21:18
• What is the stipulation of the puzzle? Nov 9, 2015 at 8:39
• @jknappen what do you mean by stipulation? The problem states "white to move, find the best move". Does that answer your question? I guess I should have included that wording in the question.

• @Matt: Yes, it does. Thanks for the clarification. Nov 9, 2015 at 14:52
• @jknappen Thanks for pointing that out. I edited the question.

You're absolutely right. Qe6 only seems to draw:

``````6k1/1p3rpp/1q1p4/p2Pp3/P5Q1/1P3PP1/2R3KP/8 w - - 3 13

1. Qe6 g6 2. Rc8 Kg7
``````

There's no forced win for white here as far as I can see.

• Do you have a link or reference for creating those boards in questions and answers? I looked through the help but struck out.

Often there are several strong moves and the puzzle solution lists just one of them.

In this case however, it seems to be a mistake. Possibly the second move was given instead of the first, with the intended solution being 1.Rc8 Rf8 2.Qe6+.
