this one is seen in many tactical books. most recently in 300 most important positions and sharpen your tactics. great puzzle that everyone should get instantly. cheers!
The features I saw at first glance is that if the White Queen checks along the a2-g8 diagonal, it’s curtains.
The pawn is guarded by the Black Queen so White can plant a rook on e7. The minor pieces can’t capture the rook without interfering with the defense of the f7 square. The White Queen’s function is to prevent a check along said diagonal.
That’s as far as I can see. If there are any intermediate moves, please improve on mine.
Against Ne5 RXN should work fine. Material is even but more importantly there still seems to be no credible defense for Black, as he has not solved his problem of two weaknesses and one move does not seem to suffice to do so.
I think 1… Ne5 2. Rxe5 counts as saving the game. White is now up in material, has superior piece mobility and threatens 3. Re7 same as before. If 2… Rae8, 3. Rxe8 Qxe8 4. Qd5+ followed by mate. I guess Black has to play 2… h6 but still doesn’t look so good.
Instead of RxN how about 2. Rxd7 Nxf3 3. Nxf3 and White is again slightly ahead in material and has a rook on the 7th. After 3…Bd6, 4 Rae1 intending Ne5 etc.; is this stuff ok or is RxN better? Maybe white has cleaned up Black’s problems that way.
and white is ahead two pawns and will soon have a rook cleaning house on the 7th rank to boot?
Alternatively, I also thought:
1. Re7 Ne5 2. QxB?!+ RxQ (or KxQ) 3. RxQ
again white is up a pawn and has a rook on the seventh rank. However, black’s rook has become more active, I prefer either your line or my first line with 3. Qxd5+.
Back to that line:
1. Re7 Ne5 2. Rxe5 g6 3. Qxd5+ QxQ (forced) 4. RxQ Bd6 (threatening to trap the rook?…or not) 5. Ne4 and the white rook must escape with the two pawn advantage.
Two pawns should be enough for a win.
Is there anything better than getting the two pawns?
instead of RxN (after Ne5) I see 2. Rxd7 Nxf3+ 3. gxf3. Now white threats Nf7 (and some black pawns are attacked, too). If black plays h6 (what else? h5 perhaps) we play 4. Se6! and because of Rxg7+ (!) black can’t move his bishop away. So white wins the second pawn (if he can play Nxc7 and Nxd5 even more) and has the active rook on the seventh rank. Black can’t get good counterplay on second row. For example 4.-, Re8 then 5.Nxc7, Re2 6. Nxd5, Rxc2 7. Rxb7 and white is three pawns up [7. -, Rd2 8. Nc7, a6?! 9. Ne6 should be +-].

Hi,
what do you do against
1. Re7 Ne5
???
Jakob
1. Re7, Ne5
2. R:e5, and Black’s position is falling apart.
Against Ne5 RXN should work fine. Material is even but more importantly there still seems to be no credible defense for Black, as he has not solved his problem of two weaknesses and one move does not seem to suffice to do so.
I think 1… Ne5 2. Rxe5 counts as saving the game. White is now up in material, has superior piece mobility and threatens 3. Re7 same as before. If 2… Rae8, 3. Rxe8 Qxe8 4. Qd5+ followed by mate. I guess Black has to play 2… h6 but still doesn’t look so good.

1. Re7 Ne5
2. Rxe5
White has qualized in material and black needs good defence.
2. … h6?
3. Re7! Qxe7 (3. .. hxg5 4. Rxd7)
4. Qxd5+ with mate to be followed
2. … Re8
3. Rxe8 Qxe8
4. Qxd5+ followed by mate
2. … g6 (Black king can have g7 for escape)
3. Re7? Qxe7
4. Qxd5 Kg7 and looks like black king escapes from mate for a while!!
However,
2. … g6
3. Re1 Kg7 (3. .. h6? 4. Re7 Qxe7(4. .. Bxe7 5. Qf7#) 5. Rxe7 with mate to follow)
With Kg7 black has an escape route to h6.
1. Re7 Ne5
2. Rxe5 g6
3. Re1 Kg7
After this I do not see a checkmate.

To P. Anandh:
White is ahead in material (one pawn) and looks positionally won after your
1. Re7 Ne5
2. Rxe5 g6
3. Re1 Kg7
Even so, why not:
1. Re7 Ne5
2. Rxe5 g6
3. Qxd5+ QxQ (forced)
4. RxQ
and white is ahead two pawns and will soon have a rook cleaning house on the 7th rank to boot?
Alternatively, I also thought:
1. Re7 Ne5
2. QxB?!+ RxQ (or KxQ)
3. RxQ
again white is up a pawn and has a rook on the seventh rank. However, black’s rook has become more active, I prefer either your line or my first line with 3. Qxd5+.
Back to that line:
1. Re7 Ne5
2. Rxe5 g6
3. Qxd5+ QxQ (forced)
4. RxQ Bd6 (threatening to trap the rook?…or not)
5. Ne4 and the white rook must escape with the two pawn advantage.
Two pawns should be enough for a win.
Is there anything better than getting the two pawns?
To P.Anandh:
Actually, you will soon win the second pawn in your line too (and it keeps tactical threats that black must find), so I go with yours:
1. Re7 Ne5
2. Rxe5 g6
3. R(a)e1 Kg7
then..
4. Rxd5 or Qxd5 wins the second pawn and leaves black fewer tactical shots than in my line.
But wait, there’s more:
1. Re7 Ne5
2. Rxe5 g6
3. R(a)e1 Kg7
and not
4. Rxd5, but
4. Ne4+ then..
4. …. Kh6?
5. Qf4+ g5(forced)
6. Qf6+ Kh6 (forced)
7. Qxg5#
so..
4. …. Kg8
5. Nxf8 Rxf8
6. Qxd5+ QxQ
7. RxQ (white has two pawns and black has no tactical threats)
Hello there,
instead of RxN (after Ne5) I see 2. Rxd7 Nxf3+ 3. gxf3.
Now white threats Nf7 (and some black pawns are attacked, too).
If black plays h6 (what else? h5 perhaps) we play 4. Se6! and because of Rxg7+ (!) black can’t move his bishop away.
So white wins the second pawn (if he can play Nxc7 and Nxd5 even more) and has the active rook on the seventh rank.
Black can’t get good counterplay on second row. For example 4.-, Re8 then 5.Nxc7, Re2 6. Nxd5, Rxc2 7. Rxb7 and white is three pawns up [7. -, Rd2 8. Nc7, a6?! 9. Ne6 should be +-].
Probably that’s an alternative to your variation.
Jochen
Two little corrections:
I meant a5?! instead of a6?! of course.
After Rxg7 there should be a mate sign #, not only a check sign.
I’m sorry.
Jochen
