Wednesday 5-second tactics
SPRAGGETT ON CHESS
Today’s tactics theme is devoted to the noble Knight. Noble–yes, but at times a NASTY beast! Hence, the origin of the chess term: knight-mare!
MISSED BRILLIANCY FROM 2013 US-CHAMPIONSHIP
gm GAREEV
ARNOLD,M
Position after White’s 14th move. No doubt a matter of first round jitters, here Gareev played the imprecise 14…Nxc3 15.PxN 000 with a sharp game in progress. HOWEVER, as Raja Panjwani pointed out to me this past weekend, Black can win brilliantly in the position above:
14…Ng3+!!
Black wins in every line!
I leave it to my readers to show that this is infact correct.

ANOTHER MISSED OPPORTUNITY!
gm ROBSON
gm STRIPUNSKY
From the US-Championship, position after 29 moves. A wild game! Here Stripunsky played imprecisely with 30.Qh4 (threatening a lethal Knight check on h7) 30…Re7! and Black, though worse, is still kicking.
HOWEVER, once again Raja Panjwani pointed this out to me, there is a remarkable and original path to victory here:
30.Rxe4!! QxQ (what else? White is threatening Nh7+!) 31.Nh7+!!
And it will be either mate or the White g-pawn will Queen!

KNIGHT-MARES: SMOTHERED MATE!
gm SHERBAKOV,R
gm SUETIN
Warsaw, 1991. Position after Black’s 35th move (35…Qg4!?) BEWARE the combined attacking potential of the Queen and 2-Knights!
Curiously, Black is threatening nothing serious (!) and should White now play 36.Ra1! –removing the Rook from any Knight attack–it is not clear how Black should proceed. Ofcourse, I think that most grandmasters would prefer the Black pieces here, but careful analysis shows that White should draw with reasonable play.
HOWEVER, we humans instinctively do not TRUST to have so many pieces about our monarch, so Suetin can be forgiven for his next move:
36.h3??
Loses immediately, in spectacular fashion!
36…Nf3+! 37.Kh1 (Moving to f1 loses simply to 37…Ned2+ )37…Qg3!!
OUCH!!
Taking the Queen is mate in one move, so Suetin played 38.PxN NxP+ 39.QxN QxQ and Black won easily.

THIS REMINDS ME OF A FAMOUS TAL-GAME….

THIS REMINDS ME OF A FAMOUS TAL-GAME….
gm PORTISCH,L
The Biel Interzonal, 1976. Position after 36 moves. The stage has been set for another knightmare: Tal–in his element–had sacrificed a piece for the attack and now has his Queen and 2-Knights within shooting range of the Black monarch…
37.Nh6!!
Threatening 38.Qg8+!! and mate next move. Neither Knight can be taken in the position above (forced mate each time). The best that Black can do is delay the mate…chess engines indicate that it is forced mate in at most 9 moves (with Black desperately giving up his pieces to survive)
So Portisch did the gentlemanly thing:
