Rdf3 does not automatically work. Since there is no immediate check black can move his/her king away from the combo. If the king goes to f7it can retreat back to the 8th and then both rook and queen are protecting the h pawn and preventing white’s pawn from queening. That would appear to make the rook sac kinda fruitless?
1. Rd3-f3 might not be the best continuation but it is the best I can see. e.g.: 1..Kg6-f7 2. Qd2xg5 Kf7-e8 3. Rf3xf6 and black is quite hopeless. For ex: 3.. Re7-f7 loses to 4. Qg5-g8 and 3..Ke8 heading to d7 is countered with 4. Qg5-g8 check Ke8-d7 5. Rg3-g7 and white threatens 6.Rg7xRe7 Kd7xRe7 and 7. Rf6-f7 mate. Black’s position is hopeless.
4. Rf6-f8 check does not work so well( 4.. Ke8xf8? 5. Qg5-g8 mate) 4.. Ke8-d7 but still black’s position is quite hopeless.
the variations you posted were almost exactly the first thing I tried, too! After 5. Rg7 !? Rxf2 I just thought to play Nf3! and the threat RxR and Qxh7+ and exchange of queens (then h6-h7-h8Q) still exists.
What I do not like is the black possibility to check with d6-d5 after Rg7. That check gives the black king one more field to go, so I’m not sure if our idea still works. But perhaps the threat Qxh7 (without exchaning everything) still wins.
But here is one single variation that could happen after 5. Rg7 Rxf2: 6. Nf3 d5+ 7. Kg1 (Kh1 Rf1+ but other king moves?) Rxf3 8. gxf3 Qd6!? 9. Qxh7 Qg3+!!
I’m not quite sure if this variation is nonsense at all because I “found” that on paper without board.
Argh, having written that I see 9. -, Qg3+!? 10. Rxg3 Rxh7 11. Rxh7 and white wins….
But nice to find someone thinking the same variation as me (and not so simple and probably better Rf3 moves ;)).
1. Rdf3

10.Q:h7 and black cant handle all the threats.
1. Rdf3. Plan: Sac the Rook on f6 and than check on g5 with queen, and mate follows.
1.Rdf3! Kf7
(1… Ra1 2. Rxf6+ Kxf6 3. Qxg5+ Kf7 4. Qg8+ Kf6 5. Rf3+ Ke5 6. Qg5+ Ke4 7. Re3++)
2. Qxg5 etc

Hello second anonym one,
the variations you posted were almost exactly the first thing I tried, too!
After 5. Rg7 !? Rxf2 I just thought to play Nf3! and the threat RxR and Qxh7+ and exchange of queens (then h6-h7-h8Q) still exists.
What I do not like is the black possibility to check with d6-d5 after Rg7. That check gives the black king one more field to go, so I’m not sure if our idea still works.
But perhaps the threat Qxh7 (without exchaning everything) still wins.
But here is one single variation that could happen after
5. Rg7 Rxf2:
6. Nf3 d5+
7. Kg1 (Kh1 Rf1+ but other king moves?) Rxf3
8. gxf3 Qd6!?
9. Qxh7 Qg3+!!
I’m not quite sure if this variation is nonsense at all because I “found” that on paper without board.
Argh, having written that I see
9. -, Qg3+!?
10. Rxg3 Rxh7
11. Rxh7 and white wins….
But nice to find someone thinking the same variation as me (and not so simple and probably better Rf3 moves ;)).
Greetings,
Jochen
Of course I meant 11. Rg7+ instead of 11. Rxh7.
I’m sorry!
