Thursday last saw one of the questions about the qualifiers to the Schenectady Finals answered. Two of the younger participants met to decided who would take the third chair from Preliminary Section A. In a mild upset Zack Calderone won a sharp Sicilian, and now will make his first appearance in the Finals.

Up to here this has been topical at top level chess for a very long time. Robert Byrne and Bobby Fischer argued the merits of the line in a blitz game in 1971. Note Byrne used the recommended plan for White; an early g4-g5 to shunt the Black Nf6 to h5 to cut down Black piece activity in the center. A creative middle game saw the advantage wax and wane for both sides until Fischer emerged with a winning endgame.

Almost forty years later the soon to be World’s number one played the line in a blindfold game against a very strong Chinese GM. He tried a similar plan to the one Byrne used, with same result. Once more Black obtained a winning endgame.

Enough of these less than fully serious games. Now we look at Anand winning a game contributing to his reaching the world title. Black takes a slower route (9…, Nb6), and White wins in the ending this time.

Sharpest and may be the best course for Black. Opposite side castling puts a premium value on time. Getting to grips with the opposing King’s guardians makes a serious difference. In the following game Black takes time to shift a Knight to b6 (12…, Nb6) and White wins once more.

Just to illustrate there are more strings to the bow for White, here is a game from a recent European Cup. In this one White plays 8 Bg5, and 9 Bxf6, not being tied slavishly to general principles (keeping the better of his Bishops) in the interest of eliminating a Black Knight that can be influential in the center.

A general conclusion is White does better if he can do something about the Black Knight on f6; drive it or trade it to reduce Black’s influence in the center. Returning to our game:
13.Nd5 Bxd5 14.exd5 a5 15.Qh2?!,..
This move struck me as unusual when it was made. I could not see how White was going to open the h-file quickly. The best idea I came up with was: h4-h5, g4-g5, and g5-g6, thinking about sacrificing the Be3 on h6 if Black advances that pawn. There problems with the idea; Black is on the move and can make threats, the White d-pawn is not well defended, and the several moves it would take to carry out the plan means the Black Q-side pawns will close with the White King’s defenders well before the White K-side pawns can do the same. White had to play 15 g5, pushing the Nf6 away from the center. Failing to do so lets Black carry out a sparkling attack.
15…, a4 16.Nd2?!,..
Better than the ugly 16 Na1, but not enough better to hold the game.
16…, Nxd5 17.Bf2?,..
Here White had to try 17 Nc4?!. Black then can take the Be3 right away, or first push 16…, b3; and either way he has good chances with the exposed White King on which to focus. The text leads to a quick finish.
Sharpest is 17…, a3; then a) 18 Bc4 axb2+ 19 Kxb2 Qa5; and White is in trouble. If a1) 19 Kb1 Nc3+ 20 Kxb2 Qa5; is worse, and b) 18 b3 Nc3 19 Re1 d5; looks horrible.
If White just did not blunder the d-pawn, this move must be the idea behind the pawn sacrifice. From e4 the Knight can go to g5 and give itself up on h7; the problem is finding the time to make this happen. A little more resistant is 18 Bg3, then 18…, Ne6 19 Kb1 Qc7 20 Nc4 Nb6 21 b3 Nxc4 22 Bxc4 Ra5; when Black has a solid advantage, but White can still fight on.
18…, d5 19.Ng5 b3
Making contact well before White can do so on the other side of the board. One useful guidepost when calculating in opposite side castling situations; the side that closes with the enemy defenders first most often wins. The threats and checks that become possible are so forcing that the opposing attack is stalled.
White has only the choice of how he wants to be mated now. The alternative 20 a3, is met with 20…, bxc2 21 Rd2 Bxa6; completing the destruction of the house of the White King. Mate will occur very shortly after say; 22 Rxc2 Bd6 23 Be3 a6; etc.
20…, axb3 21.c3 Qa5!
My first reaction here was 21…, Ra1+ 22 Kd2 Rxd1+?!; but White can resist with 23 Kxd1 Qa5 24 Be3, and things are not quite clear yet. The text ups the ante immediately. With the Queen on the field mate looms.
Also lost is 22 Bg3 Qa1+ 23 Kd2 Qxb2+ 24 Ke1 Qxc3+.
22…, Nxd3+ 23.Rxd3 Qa1+ 24.Kd2 Qxb2+ 25.Ke1 Ra1+ 26.Rd1 Rxd1+ 27.Kxd1 Qc2+ 28.Ke1 b2 0–1
White will soon be down a whole Rook, and worse still, Black retains a strong initiative that will permit him to force off most of the remaining pieces leaving a won ending.
Quite an interesting game from these two youthful players maybe foretelling an important rivalry for the next few years at Schenectady. Such clashes between up and coming youngsters have in the past been key to the Schenectady Club’s being the largest of the local clubs. When we get a couple of rivals battling for a higher place in the pecking order, it seems to attract others to the club wanting to measure themselves against the rivals. Here’s hoping this is the case now.
