Tactical Blows by Kotov


    
Today’s game is another instructive win by Alexander Kotov. This time the victum was the English IM Harry Golombek (1911-1995, 83 years old). Born in London, he warded the IM title at its inception in 1950 and an Emeritus GM title in 1985. Golombek was British Champion in 1947, 1949 and 1955. He was an accomplished author with biographies on Capablanca and Reti as well as other lesser known chess books. 
 
 
 
 
 
    In this game Kotov again demonstrates his tactical prowess. We all enjoy tactics and this game shows how sometimes in a very deeply calculated variation a surprise tactic is lurking. And, sometimes they are found only by accident. In this game Kotov used a tactical blows to solve a comp1icated strategical problem.
 

A game that I liked (Fritz 17)

Nc3 Bb4 4. a3 {This sharp move, the Saemisch Variation, has fallen into disuse in favor of the Rubinstein Variation (4,e3) or the Capablanca Variation (4.Qb2). Originally 4. a3 was a direct attempt to refute the Nimzo0Indian. White accepts doubled Ps to get the two Bs.} Bxc3+ 5. bxc3 {Black has several possibilities; the most common is to blockade the c-Pawns with 5....c5 and then proceed to attack them with ...b6, ...Ba6, ... Nc6-a5 and ...Rc8. As compensation, white gets a strong P-center.} d6 {This seldom played move has not proven very successful.} 6. f3 (6. e4 {This is an interesting move suggested by Stockfish which has been played only rarely. In the few example I foind black always played 6...e6, bit theengine line looks intriguing.} Nxe4 7. Qg4 f5 8. Qxg7 Qf6 9. Qxf6 Nxf6 10.

Ng3 {This makes room for the Q on e2 in the event black plays ... Na5 with a double attack on the P on c4. In failing to play 11...Na5 Golobek's position begins to deteriorate.} Qd7 {The Q is badly placed here as it allows white to carry out a P maneuver which secures him a positional advantage.} 12.

Consequently, Kotov decides to block the center which sets a clever tactical trap.} Na5 { Attacking the c-Pawn is routine and quite logical, but Golombek has not noticed the lurking dangers. Although white still has the better of it, challenging the N on e5 with 14...Ne7 was better.} 15. c5 {[%mdl 544] Kotov makes an astute observation stating that "tactics are the service of strategy. " With this move white turns the weak c4 square into a strong styrategic outpost. that practically decides the outcome. Whi te's strong P-formation separates so that they are unable to offer any coordinated resistance.} Bxd3 16. c6 {Driving a serious wedge in black's position.} Qd8 17.
