In the following blitz game played at ICC Black is in possession of the , sometimes very overrated, two Bishops. He just played the unimpressive b4 which blocks the position somewhat adding value to the White Knight.
John Watson’s excellent tome titled Play The French is fond of phrases like White square blockade when the author is treating some of Winawer variations. White Square Blockade always sounded so erudite and unexciting to me, but in the following position White can achieve an unbreakable light square blockade forcing the Black Laufer to skip about the board in a desultory (One of Bisguier’s favorite terms) fashion lost in space.
White can take his time strengthening his position with the goal of King infiltration after the light square bind is strengthened with g4. The sequence of moves that leads to the White Square Blockade is 34. Bxe6 Kxe6 35. Ke4 ! establishing light square hegemony. Note that recapturing with pawn at e6 is possible but that permanently cedes control of e4 to the first player and will probably eventually manifest as Zugzwang for bound and gagged Black.
White literally owns f5 with the g3 steed steaming at the mouth for occupancy! Now the phrase White Square Blockade feels much more like something worth striving for in a chess game!
Edward Winter’s The Most Famous Chess Quotations supplies us with a very relevant Nimzowitch quote: Zuerst hemmen, dann blockieren und schließlich vernichten translated as first restrain, next block, and then destroy.
