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

``````[FEN "1r1r2k/p4pp/2q/2p1p2P/P1P1Pn/B3NP/4Q2P/R6K w - - 0 1"]

1. Nd5
``````

The White queen is under attack, yet one shall not rush and capture it. The White may fork the Black king and queen and then fork two rooks:

``````[FEN "1r1r2k/p4pp/2q/2p1p2P/P1P1Pn/B3NP/4Q2P/R6K w - - 0 1"]

1. Nd5 Nxe2
2. Ne7+ Kf8
3. Nxc6 Ke8
4. Nxb8 Rxb8
``````

So, we lose a rook here. Therefore, we need to capture the knight. I took the knight with the rook:

``````[FEN "1r1r2k/p4pp/2q/2p1p2P/P1P1Pn/B3NP/4Q2P/R6K w - - 0 1"]

1. Nd5 Rxd5
``````

Yet, chesstempo wanted me to capture it with the queen:

``````[FEN "1r1r2k/p4pp/2q/2p1p2P/P1P1Pn/B3NP/4Q2P/R6K w - - 0 1"]

1. Nd5 Qxd5
2. cxd5 Nxe2
``````

So, why do we play Qd5 instead of Rd5? Besides, does it matter for the White whether to play cxd5 or exd5 on the last board as the second move?

• @David yep, that was a silly blunder which I didn't see for some reason :P. Dec 22, 2020 at 18:43
