Recognising the pattern : Challenge # 18

Hugh Edward Myers against Dmitri Poliakoff in 1955: White to move

Q: Here Black has the initiative but is far from winning. His last move was 47…Qc4 which sets-up a trap. Can you see it?

A: In the game, White failed to do so and lost in the next two moves:

48. Ra4 Qxf1!! 49. Bxf1 – Nf2#

Instead White can prolong the fight with 48. Rb2.

This mechanism of checkmating is called the corner mate, the fourth way of checkmating with rook and knight. Others are the Anatasia Mate, the Arabian Mate & the Hook Mate

Torre against Ribli in 1983: Black to move

Q: In this position, Black played 66…Rd8 which leads to quick disaster. Can you see how?
A: Torre replied with:

67.Nb5 Ka8

67…Kb8 leads to the same result.

68. Rc7!

Mate can’t be prevented. The idea is to play Ra7 & Rb7 followed by mate with a knight check from c7 or a7.
The pain can be prolonged with 68…Rh8 but instead he choose to throw in the towel.

Georgios Makropoulos against Ivan Farago in 1988: Black to move

Knowing the pattern doesn’t always leads to checkmate. Here in this example you can win some material based on pattern as white can avoid the worse.

Q: How will you proceed from here?
A:

29…Nxe4!!

White should now play 30. Rf1 in order to stop checkmate. Instead he blundered:

30. Nxf4?? Nf2#

If 30 fxe3 then Qxe4 leads to mate. Only 30. Rf1 can extend the fight but black should win because of his two extra pawns.
