1…Rc3 2.Ra2 Rf3 3.Ke2 Rf2 4.Kd1(d3) Qa2
Rxc3!
Rxc3!
1 rxf3 wins
Rxc3!
Rxc3
R x c3
Txc3!! y todo se acaba por las multiples amenazas!
1. Rxc3 looks tempting. 1. … bxc3 is impossible because of 2. Qf2# White’s position looks very exposed.
Sicilian Najdorf players always sac their rook on c3-square, right?
1. … Rxc3 threatens 2. .. Rf3+ 3. Ke2 Qe3+ 4. Kd1 Rxa1+ 5. Nxa1 Qc1+ 6. Ke2 Re3+
If 2. bxc3? Qf2#
2. Nd4, to stop Black from playing Rf3+, simply loses a piece to 2. .. Rxa1 3. bxc3 Rxe1+ 4. Kxe1 exd4
If 2. Rxa2 Rf3+ 3. Ke2 Rf2+ and White has a choice between 4. Kd3 and 4. Kd1
4. Kd1 Qxa2 (threatening Qb1+) 5. Qd3 Rxb2 and White is busted.
4. Kd3 Qc7 (threatening Qc2#) 5. Ra8+ Kh7 6. Nc5 (6. Nd4 Rd2#) 6. .. Rd2+ 7. Kc3 Rxd5 8. exd5 Qxc5+ 9. Kb3 Qc4+ 10. Ka3 Bd2 11. b3 Bb4+ 12. Kb2 Qc3+ 13. Ka2 Qc2+ 14. Ka1 Bc3#
In this last sequence 6. Rc1 is unavailing, since after 6. .. Bxc1 7. Nxc1 Qxc1, Black threatens 8. .. Qd2#, and there is no way mate can be avoided.
1. … Rxc3 seems to do the trick and the white’s position falls apart.
1… Rxc3
if
2. Rxa2 Rf6+
3. Kg2 Qf2+
4. Kh1 Qxe1+
0-1
or 3. Ke2 Rf2+
and 4…. Qxa2 -/++
after 1… Rxc3, there is no good way to prevent 2… Rf3+. if
2. Nd2 Rxa1
Rxc3
1… Rxf3
White cannot play 2. g2xR
because then 2…Qc2++
If 2. RxR Rc3+
3. Kd2 (Kb2 also leads to mate very quickly after Qc2+)
3….Rc2+
4. Ke1 (if Kf3 Qd3++)
4… QxR
and there is no defence aganst mate on the first rank unless White loses his Queen (5. Qe2) and even then the mate is only delayed a few moves.
