Fischer chess tactic



Black is Fischer. White is Unzicker. It is Black to move. Can you find the crushing continuation for Fischer?

1 rook takes pawn c3

1...Rxc3 exploiting the active positions of black's pieces and creating threats against the white king.

Difficult. And saying 1... Rxc3 doesn't tell you much. Yes it's probably the initial move but, for instance, what happens after 2.Rxa2 Rf3+, 3. Ke2 and either
[A] 3.... Rf2+
4. Kd3 or
[B] 3... Qf2+
4.Kd1

And 2. Rxa2 is not obviously forced either although I think the critical variations result from that move. Obviously White can't simply recapture the Rook on c3 [2.bxc3?? Qf2 mate] but White can even try 2. Rab1 - passive defense to keep Rooks connected and protect the b pawn and 2nd rank from becoming totally opened up. Or 2. Kg2 to guard against the Rook check at f3. So there's a lot to look at here and it's little surprise that I can't readily solve what a Fischer could, even when I'm told there's a tactical solution here.

Looks like normal chess to me.

1. Rxc3 looks very interesting indeed, but complicated. I was heavily puzzled by the number of lines. But I might have played this move even without knowing if it was winning or not, in the absence of anything more promising.

A)
1. ... bxc3??
2. Qf2#

B1)
1. ... Rxa2? (does nothing against the threat)
2. Rf3+ Ke2
3. Qe3+ Kd1
4. Rxa1+! Nxa1/Nc1
5. R(x)c1#

B2)
2. ... Kg2
3. Rxb2+! Nd2
4. Qf2+ Kh1
5. Rxd2 Qxd2
6. Bxd2

C1)
1. ... Kg2
2. Rxb2+ Kh1?
3. Qf2 Nd2
4. Rxg3 and Rxh3# next

C2) (critical ?)
2. ... Nd2(!)
3. Rxd2+ Qxd2
4. Bxd2 Rxa7
5. Bxe1
should be up with a knight, as should also be the result of
4. Qxa1

D)
1. ... Ke2
2. Qe3+ Kd1
3. Rxa1+ is the same ad B1 above.

E)
1. ... Nd2 (or other N moves)
2. Rxa1!
is simply up with a rook.

As Craigaroo points out, it really is complicated (if at all possible) to make Rxc3 work.
In my first post I think something went wrong (a black rook was in 2 places at the same time).

pht said...

1. ... Rxc3
2. Rxa2 Rf3+
3. Ke2 Rf2+!
4. Kd1/Kd3 Qxa2!
How to defend b2 pawn now?
Doesn't black have strong attack here?

2. Rb1 Rxg3!
looks strong.

2. Kg3 Rxb2+!
looks strong.
3. Nd2 (Kh1 Qf2) Rxd2+
4. Qxd2
Both queens go, but black seems to be up with knight in the end?

Mr Anonymous....
that's why you are not bobby fischer - so it's normal chess to you.
You need to go beyond to see why and what?

Lucky.
