RE: Chess problem 73 / Schachaufgabe 73

in #chess5 years ago
  1. Nxe6 dxe6 (forced else NxQ)
  2. d7 Bxd7
    2... Ke7 dxc8=N+, black captures however then g4 and g7 will fall and black's king side is destroyed. Black king in the center with lots of active pieces on the board
  3. Rxd7 threatens mate Ne7 only def
  4. Rxa5! Probably the move you wanted us to find

At this point black has huge issues on back ranks. Cant capture queen or rook else mate in one. Then I guess Ba3 will be too strong and black will have to either get mated or give back too much material. Actually I'm not sure it seems quite complicated because white has a back rank issue too but at least it's a fun position and as it's a lightning game you'll win because you are on the offensive and your opponent is very likely to blunder and get mated.

Sort:  

That's the main idea and thus I declare you as winner of this round! :)

What would you play after:

1. Nxe6+ dxe6
2. d7 Bxd7
3. Rxd7 Ne7
4. Rxa5 Rc8 ?

By the way the computer program Stockfish just showed me a really tricky defense in one variation which limits the white advantage (which still exists, however). So in case you are interested just wait for my later solution comment.

Yeah thats what I meant by back rank weaknesses. Rxe7 Qxe7 then Ba3 leads to b4! Bxb4 Qxb4 for blacks and Rc1 would be mate. b4 is possible because queen moved (otherwise the b pawn is pinned), so maybe theres a way to go for Ba3 before?

It's very tactical and in a lightning game i'd still favor whites heavily

Yes, this is a clear advantage for white.

At one point in this whole variation black has a better defence so that in the end he only loses one pawn. Maybe you like trying to find that, but if not, I will show you later. :)

Is it Kg8 at one point? I looked at that briefly but whites can do Qf7+ Kh7 then c4 to open the last rook and threaten Qh3, seems brutal but I dunno how it works in practise

It is a variant that starts after 4. Rxa5.

I am a bot. I turn comments into owl related puns.

I would start with 1. Rxa5 first and then the moves you gave.

1. Rxa5 Rxa5
2. Nxe6+ dxe6
3. d7 Ke7
and black wins. :)

Nah because then blacks can give up the queen to defend with Qe7 Rxe7 Nxe7 and black has initiative again with 2 rooks for a queen... Can't be winning for whites
