Body: <p><a href="https://chesstempo.com/chess-problems/90726" rel="noreferrer">This puzzle</a> on <a href="https://chesstempo.com/" rel="noreferrer">chesstempo</a> caught my eye. We play as Black:</p>
  <pre><code>[FEN &quot;1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 0 1&quot;]
  
  1.Rgxg5
  </code></pre>
  <hr />
  <p><strong>Note:</strong> <em>the solution is not quite important here, so no large spoilers from me :).</em></p>
  <hr />
  <p>The main blunder here is playing 1... Bxf5. One of the comments runs:</p>
  <blockquote>
  <p>...Black is a step away from certain death after 1...Bxf5 2.Qxf5...</p>
  </blockquote>
  <p>They show this board:</p>
  <pre><code>[FEN &quot;1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 1 1&quot;]
  
  1.Rgxg5 Bxf5 2.Qxf5 Qd1+ 3.Rg1 Qd2 4.f7 Qf4 5.Qe6 h5 6.Rg8+ Rxg8 7.fxg8=Q+ Rxg8 8.Qxg8#
  </code></pre>
  <p>Is mate threat really a thing here? I believe the mate threat actually begins at 3... Qd2 4. f7. Here's how I would've answered:</p>
  <pre><code>[FEN &quot;1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 1 1&quot;]
  
  1.Rgxg5 Bxf5 2.Qxf5 Qd1+ 3.Rg1 Rxd5
  </code></pre>
  <p>I reckon 3... Rxd5 to force White into some exchange, as merely playing 4. xd5 would end up in a mate threat from Black:</p>
  <pre><code>[FEN &quot;1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 1 1&quot;]
  
  1.Rgxg5 Bxf5 2.Qxf5 Qd1+ 3.Rg1 Rxd5 4. cxd5 Qxd5+ 5. Rg2 Rg8
  </code></pre>
  <p>The exchange would be:</p>
  <pre><code>[FEN &quot;1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 1 1&quot;]
  
  1.Rgxg5 Bxf5 2.Qxf5 Qd1+ 3.Rg1 Rxd5 4. Rxd1 Rxd1+
  </code></pre>
  <p>So, who is wrong here? Am I failing to choose the best moves for White, or is the board in the comments actually faulty?</p>

Comments.Text: How does black respond if white in your last diagram plays 4.f7 instead of 4.Rxd1? White is threatening mate both by means of Qf6 and f8Q, and as far as I can see it's difficult for black not to lose Q+R for white's R.

Comments.Text: @Scounged 4... h5? The White rook is pinned, so the mate on the board from the comments couldn't really be carried out (well, I see no way).

Comments.Text: After 4...h5 white plays f8Q followed by a trade and mate on g7.

  This puzzle on chesstempo caught my eye. We play as Black:

  The exchange would be:
  [FEN "1r1r3k/7p/5Pb1/p2BpRpq/1pP5/1P1Q4/P5RP/7K w - - 1 1"]
  
  1.Rgxg5 Bxf5 2.Qxf5 Qd1+ 3.Rg1 Rxd5 4. Rxd1 Rxd1+
  
  So, who is wrong here? Am I failing to choose the best moves for White, or is the board in the comments actually faulty?
