White to move. How should White proceed?
Bxh7!?
How about
1. Rxe7 Qxe7 (or Rxe7 Bxf6 gxf6 Qh6 and things don’t look so hot at first glance)
2. Nxd5 Bxd5
3. Rxd5 Nxd5?
4. Qh4! as a starting point for analysis…
Nxe7 … Qxe7
Bxf6 … gxf6
Qh4
Re7 Qe7 Bf6 Qf6(pf6 Qc7) Qf5 Qe4 Ne4 Pe4 No worth Force can stop mate. 1-0
Re7 Re7 Bf6 Gf6 Qf5 Re4 Be4 is decisive
Also to the blogger that posted before me After Qh4 black has the saving resource f5!
1. Re7 Qe7
2. Bf6 Qf6 (if gf6, then Qf5 or Qh4)
3. Qc7
1. BxH7 … Kxh7
2. Bxe7 forking queen and rook.
white advantage
^^^
Sorry I meant to put 1. …Nxh7
Rxe7 Qxe7
Bxf6 gxf6
Qg4+ Kh8
Qf5 +-
everyone wrong! QH4 is crushing!
1. Rxe7 Qxe7
2. Fxf6 gxh6 (if … Qxh6 3. Qxc7)
3. Nxd5 and white wins
1.Rxe7.
If 1. … Rxe7 then 2.Bxf6 gxf6 3.Qf5
If 1. … Qxe7 then 2.Bxf6 Qxf6 (2. … gxf6 3.Qf5) 3.Qxc7
Bxf6 Bxf6
Nxd5 Bxd5
Rxd5 Qxd5
Qxc7
1. Rxe7 Qxe7
2. Bxf6 Qxf6
[2…gxf6?
3. Qg4+ Kh8
4. Qf5 Qe4
5. Nxe4 …]
3.Qxc7…
Qf5
After 1. Qf5, 1… g6, I don’t see White has anything.
1. Rxe6 Qxe6
2. Rxe6 Bxf6
3. gxf6
Black’s pawns are messed up but W is down an exchange, is there enough compensation?
To be honest.. it looks like there are tons of moves that win after Rxe7.
I try to transcript my thought process to solve this position:
First I see that h7 is a weak point(Already attacked once by Bb1, Nf6 could be removed and some tactics could come with the queen (I see Qh4, Qg4 or Qf5) and/or Nf3-Ng5…) so I try 1.Bxf6 Bxf6 2.Qf5 but g6 stop my attack completely…
during the process I also see that if not 1…Bxf6 but 1…gxf6 2.Qf5! and nothing can stop my attack (mate on h7)
So I have my first tactical theme: Black can’t take with …gxf6 and MUST take with the bishop… so I try to remove this piece and 1.Rxe7 comes to mind.
Black has no counter-threat so he must take (1…h6 and 2.Rxc7…) either 1…Rxe7 2.Bxf6 (our theme; 2…gxf6 impossible 3.Qf5 etc) 2…Rfe8 (the rook is pinned, he must protect it (and hope…)but 3.Bxh7 and then bringing in the Queen and Ng5 is hopeless (3…Kxh7 4.Qh4+ Kg8 5.Ng5 …)
We see that 1…Rxe7 doesn’t work so the second choice for black is 1…Qxe7 2.Bxf6 (once again …gxf6 impossible due to Qf5) 2…Qxf6 and another tactical trick has come: We have deflected the only defender of Rc7 so 3.Qxc7 (attacking at the same time Na5 and we have a slight material advantage, the initiative and the possibility of attacking some of black’s weaknesses (a6 and d5).
Resume: 1.Rxe7 Qxe7 2.Bxf6 Qxf6 3.Qxc7 Nb3 4.Qa7
