<Nerwal: T. Kosintseva played a nice attack :

She punished 23. d4 (instead of the correct 23. f3 defending in a better way f2) with 23... c4!, a deflection from f2 with a rook sacrifice. The sweet point is that after 24. xc4 xf2 + 25. h2 black didn't take back the rook, which would relieve white's defence, but played 25... d2!, which would win the queen after 26. xd2 e3. White played 26. d3 instead and got checkmated.>

A *beautiful* combination by T. Kosintseva, rightfully deserving a place in my game collection <COMBINATIONEN!>.

Black has just played 22 ... ♕d8-h4, menacing the f2-sq. Do you <DEFEND> against this threat by playing 23 ♕e3-d4 or 23 ♕d3-f3 ??

23 ♕d3-d4? <exposed defender>


click for larger view

Mikadze playing White chose the <BLUNDER> 23 ♕d3-d4?. 23♕d3-f3! was the correct move as the White f3-queen is not as <EXPOSED> to attack on f3 as she is on d4.

(VARIATION)
23 ♕d3-f3!

Game Collection: YOU DO NOT WANT YOUR DEFENDERS TO BE EXPOSED TO ATTACK! 23 Qd3-d4? exposes f2-sq defender to attack, Qd3-f3! does not

23 ... ?

Continuing with my above kibitz, why is 23 ♕d3-f3! a much better move than the <BLUNDER> 23 ♕d3-d4? ? Because on the d4-square, the White d4-queen <DEFENDER> is subject attack! <REMOVE THE GUARD>!!!

23 ... ♖c8-c4! <attack defender: f2-sq>

24 ♕d4x♖c4 ♕h4xf2+ 25 ♔g1-h2

And now instead of grabbing the White e1-rook to regain material and <CASH IN TOO EARLY>, T. Kosintseva playing Black played the much, much <STRONGER THREAT (EST)> 25 ... ♘e4-d2!.

25 ... ♘e4-d2! <<line-clearance: b7->g2>


click for larger view

This brilliant <ZWISCHENZUG> is based on the <LINE CLEARANCE> theme, vacating the a8-h1 diagonal with <TEMPO> on that <EXPOSED> White c4-queen to create a <DISCOVERY CHAIN> whose <VICTIM POINT> is the <LOOSE SQUARE NEAR THE ENEMY KING>, the g2-sq.

The tactical point is that if White captures the Black d2-knight with 26 ♗c1x♘d2, White plays the <DISCOVERED ATTACK AGAINST A SQUARE> 26 ...♘d5-e3!, threatening both 27 ... ♘e3x♕c4 and 27 ... ♕f2xg2#.

(VARIATION)
26 ♗c1x♘d2 ♘d5-e3! <discovered attack: c4, g2>

A *stupendous* combination by T. Kosinstseva. But this combo did not appear by accident. Her <CENTRALIZATION> and <LIGHT-SQUARED DOMINATION> is immense with the <LIGHT-SQUARED> Black b7-bishop, d5- and e4-knights and f5- and e6-pawns.

Hat tip to <Nerwal> for pointing this great combination out to me. :-)
