Yes, Black has the obvious threat:
1… Re1+ 2. Rxe1 dxe1(Q)#
In light of Black’s threat, White has only a few moves worth considering:
- 1. Kf1 — defends the e1-square.
- 1. Bb4 — defends the e1-square through an X-ray.
- 1. h3 (or 1. g3) — may seem playable, but we can calculate that after 1. h3 Re1+ 2. Kh2 Rxd1 3. Bxd1, the knight on b2 is left hanging.
White must play 1. Kf1 or 1. Bb4. Any other move loses after 1… Re1+.
In this position, Black’s threat was obvious. In the next example, we will see a situation where the threat is not so obvious.
Note: Sometimes, if you have strong tactical skills, you might spot a move that instantly wins the game despite any threats your opponent may have—for example, a mate in one. In such cases, there’s of course no need to analyze your opponent’s threats in detail.
