Canadian Corr Championship K53
The system chosen by White is not one of the critical lines against the Tchigorin, and here 6. Qb3 looks somewhat better (dating back to the game Pillsbury-Tchigorin, St. Petersburg 1895-6), although Black has no problems in this line either.
This move emphasises Black's dark square control and the poor White QB.
Black's strategic advantage is clear, but converting it into a win proves no easy task, with White putting up a determined and skilful resistance.
Black's plan is to post his King on e6, then slowly increase the pressure by creating a passed Q-side pawn, and eyeing a possible later K-side breakthrough.

Many times during this long ending I despaired of finding a breakthrough, even though this was my last game to finish in the tournament, and I knew I needed the full point to be assured of at least a tie for first place.
And with the threat of 75. ... Nxd4 White resigned. As it happened, the full point was enough to gain sole first place and the Canadian title!0-1 [Dr Eugene Gibney]
