White to move. How should white proceed?
1rb3rk/2p2ppp/p7/5P1N/q3p3/P1p3Q1/1PP3PP/2KRR3 w – – 0 1
Rook D1 to D8, the rest is clear after that.
Piece of cake.
1. Rd8 cxb2+
(1. .. g6 2. Qe5+ f6 3. Qxf6#)
(1. .. Rxb2 2. Qxg7#)
2. Kb1 Bxf5 3. Qxg7#
1. Rd8 seems obvious. Black has to yield enormous amounts of material to even delay mate.
1. Rd8 and black cannot avoid mate
Qxc3 seems like a very logical move, also stop and tactics for black on b2. You can also play Qxc7, looking to brink your rook to d8 for bank rank mate in 2. Even Qxc3 targets the c7 pawn looking to bring your rook to d8 for a mate in 2 again. I did not see anything plausible with the queen, pawn, and rook on the king side… but I could’ve missed something, It’s 1am haha.
1Rd8 wins
… Nevermind! f Pawn push, then gxf6, then pin the rook on g8 with Rdd8, leding to mate in one. Or! Even sac the queen with Qxb8 after gxf6 and then Rd8# is mate.
Rd8 cxb2+
Kb1 Qd4
Rxd4
Rd8 cxb2
Kb1 g6
Qe5 f6
Qxf6++
Black is cornered and loses heavy material
1.Rd8 cxb2+
(1…Rxd8 2.Qxg7#)
(1…Qe8 2.Rxe8 Bd7 3.Rxb8)
(1…Bd7 2.Rxb8 Be8)
2.Kb1 Qd4 3.Rxd4
once the g7 pawn moves the queen takes the pawn at c3. rook down to the 8th rank is forcing.
I think Rd8 leads to the loss of the Black Queen, otherwise white mates by Qxg7.
1.Rd8 Rxd8
2.Qxg7#
1.Rd8 B-any
2.Qxg7#
1.Rd8 Qe8(only delays)
2.Rxe8 any(except g6,g5,or cxb2+)
3.Qxg7#
If 2….g6 Or g5
3.Qxc3+(Qe5+) f6
4.Qxf6#
If 2….cxb2+
3.Kb1 then the rest as above.
1.Rd8 g6 or g5
2.Qe5 f6
3.Qxf6#
1.Rd8 Qd4(to protect the g7 square)
2.Rxd4 and I don’t see black surviving
after white doubles his rooks on
the d-file.
f6
Rd8?
If there any escape from 1. Rd8!! – can’t see it myself. Threat is 2. Qxg7#.
1. Rd8!!
1… g6
2. Qe5+ f6
3. Qxf6#
Black can prolong the agony by:
1… cxb2+
2. Kb1 Qxc2+
3. Kxc2 b1Q+
4. Rxb1 Rb2+
5. Rxb2 and the checks have dried up.
The only move that strikes me as worth something is:
1… Qd4
2. Rd1 cxb2+
3. Kb1 Qxd1+
4. Rxd1 Bxf5
5. Qxc7 which still is quite a lost position for black.
The black c3 pawn seems really troublesome for white, e.g. 1. b3?? Qxa3+ 2. Kb1 Qb2#. Or 1. bxc3? Qxa3+ 2. Kd2 Qf8 and black stands excellently as far as I can see.
So white must find an immediate attack:
1. Rd8!!
Threats 2. Qxg7# weather black takes or not takes on d8.
1. … g6 (Qe8 or Qd4 were only delays, to keep g7 protected just one more move)
2. Qe5+ f6
3. Qxf6+ Rg7
4. Qxg7#
So, I would call this mate in 5.
1Rd8 cxb2+
2Kb1 g6
3Qe5+ f6
4Qxf6#.
To avoid mate black has to give up Q by 2… Qd4.
Rd8 plays itself:
1. Rd8 cb2 (g6 2.Qe5+-)
2. Kb1 and what now for black? Bb7 allows Qg7# and g6 still allows mate starting with Qe5. There is no defense I can see other than giving up the queen at d4.
If I said mate in 5, I certainly meant mate in 4:
1. Rd8! Qd4/Qe8 (Rxd8 Qxg7#, Rxb2 Qxg7#, f7/f6 Qe5+)
2. Rxd4/Rxe8 g7
3. Qe5+ f6
4. Qxf6#
I guess Rd8 is obvious the only point is for how long can black delay the checkmate.so according to me 1.Rd8 cxb2+ 2.Kb1 Qxc2+ 3.Kxc2 b1=Q+ 4.Rxb1 Rb2+ 5.Rxb2 g6 6.Qe5+ f6 7.Qxf6#…though 1..Qd4 2.Rxd4 Bxf5 is still very bad for black…anyways those who said that there was a mate in 5 or 4 possible must check the other variations as well
Rook D1 to D8, but black can cause long delays. For example:
1.Rd1–d8 c3xb2+ 2.Kc1–b1 Qa4–d4 3.Rd8xd4 Bc8xf5 4.Qg3xc7 Bf5–g6 5.Nh5–f4 Bg6–f5 6.Re1–d1 h7–h6 7.Qc7xf7 Rb8–f8 8.Nf4–g6+ Bf5xg6 9.Qf7xg6 a6–a5 10.Rd4–d7 Rf8–f6 11.Qg6xe4 Rf6–b6? 12.Rd7xg7 Rg8xg7 13.Rd1–d8+ Rg7–g8 14.Qe4–e5+ Kh8–h7 15.Rd8–d7+ Kh7–g6 16.h2–h4 Rb6–d6 17.h4–h5#
(used Fritz 13 infinite analysis to find best replies for each side)
Rd8 wins.
