Black to move. How should Black proceed?
Source: ChessToday.net
Looks like black can simply win a piece with
1 … Rxf2
2 Qxf2 Qxd1
White gets mated if he tries something fancy with:
1 … Rxf2
2 Rxd4?? Qxg2+
3 Rxg2 Rxd1#
Black can win a piece by just taking that knight at f2- the queen is pulling double duty:
1. …..Rf2
2. Qf2
Not taking at f2 isn’t an option for white as 2.Rd4 is mate in one after Qg2:
2. …..Rd1
And black is up a piece.
Now, can black do better? I don’t immediately see anything better, but I keep having this nagging suspicion I am missing a mate here. I have tried the exchanges in different order, but I keep coming up with black up only a piece- at best.
Guess I will just post my comment and see how quickly it appears.
Doesn’t Rxf2 Qxf2 Rxd1 just win a piece?
Black should proceed by winning the
knight at f2 by taking it with his
rook. If the white queen takes the
rook at f2, then black will capture
the rook at d1.
1. …Rxf2
2.Qxf2 Rxd1
3.Rxd1
black’s threat is Rd2 with tremendous
pressure on the g2 square.
3. …Qxd1+
4.Qg1(forced) Qxg1
5.Kxg1 Nxa4
and black should win easily with a
queenside pawn majority, a center
passed pawn, and an extra piece.
Instead of recapturing at f2 white
might try
2.Rxd4 hoping for …Rxc2
3.Rxd5 exd5
4.Bxc2 where white emerges the exchange up.
Black doesn’t have to exchange Queens, instead
2. …Qxd4 protects the rook at f2 and
black remains a piece up.
If R were not at g1, Qxg2#
If Q were not at c2, RxR, RxR, Qxg2#
1. RxN (a) QxR
2. RxR RxR
3. QxR+ Qg1
4. Bxg2#
1. … (b) RxR
2. QxR Qc1
3. Rxb2
White is a knight up, and the queenside pawns are coming. I may be too much of a patzer to see the forced mate.
Mark
…Rxf2!
now if
Qxf2, Rxd1 will win a rook
and if
Rxd4, Qxg2+
Rxg2, Rf1++
Rxf2
1…Qxg2+ looks good
2.Rxg2 Rxf2 , for example:
3.Qxf2 Rxd1+ 4.Qg1 Bxg2+ 5.Kxg2 Rxg1+ 6.Kxg1 Nxa4 etc.
1. b3 Qe2 2. Rxf2 Qxf2 3. Rxd1 Rxd1 4. Qxd1+ Qg1 5. Qxg1+ Kxg1 6. Be4 Bxe4 7. Nxe4 Kf1 8. c3 bxc3 9. b2 Ke2 10. b1=Q #White resigned because black had a queen and a knight ready to checkmate anytime… – KNOCKOUT2010
Black seems to be a knigt up after:
1. Rxf2 Qxf2
2. Rxd1
1…Rxf2
2.Qxf2 Rxd1
or
1…Rxf2
2.Rxd4 Qxd4
Armando/Brasil
Thinking outside of the engine, Black can do this:
1 … Qxg2+!
Yes, the chess engines state that Rxf2 gives Black a higher point score. The given move also wins and simplifies the position more in most variations.
2 Rxg2 Rxf2
3 Kg1
The most interesting try. Nothing else is any better:
A
3 Qxf2, Rxd1+, 4 Qg1 Bxg2+, 5 Kxg2 Rxg1+, 6 Kxg1 Nxa4, and White’s b pawn will fall next, with an easy win for Black.
B
3 Rg1 Rxc2, 4 Bxc2 Rd2, 5 Bg6 Rxb2, and Black can trade both Rooks for his Rook and Bishop and win as pleases.
C 3 h3 Rxg2, 4 Rxd4 Rxc2+ leads to the same basic position as the main line.
D 3 Qc1, Rxg2 4 Rxd4 Rc2+ leads to the same basic position as the main line.
3 … Rxg2+
4 Kf1
4 Rxg2 Rxf1+, 5 Qf1 (5 Kf2 Bxg2) Rxf1+, 6 Kxf1 Nxa4.
4 … Rxc2
5 Bxc2
5 Rxd4 Rxc1+ 6 Ke2 Rxb1, 7 Rxc4 Rxb2+ leaves White two pieces and two pawns down.
With the given move, White tries to at least hang on to the a pawn.
5 … Rxd1+
6 Bxd1 b3
Black cuts off communication.
7 Be2
White can’t stop Black from winning both the a and b pawns. White is hoping for the careless 7 … Nxa4, which still wins easily but allows Black to play a while longer after 8 Bxc4.
7 … b3!
Now White can’t stop Black from promoting a pawn.
1….. Rxf2
2:Qxf2 Rxd1
3:Rxd1 Qxd1
wins a piece.
Quorthon.
