Northern Ireland came into the game with Sheffield Wednesday keeper Pierce Charles making his debut but it was his opposite number Lapoukhov who was by far the busier of the two stoppers.
Indeed, the first 45 minutes developed into something of a personal battle between the Dinamo Minsk man and Jamie Reid.
The Stevenage forward, who scored on debut against Romania back in March, was making his return to the side after a blood clot in his leg saw him miss last month's games against Luxembourg and Bulgaria.
Four times in the first half the 30-year-old had decent sights at goal, but four times Lapoukhov proved his equal.
Reid's ninth minute header had seemed destined for the corner, only for the keeper to claw the ball away. While Conor Bradley, who was captaining the side for the first time, turned in the rebound, he did so from an offside position.
Put through ten minutes later by Trai Hume's long pass, Reid beat the offside trap but Lapoukhov got a right leg to his effort. When another of his shots was beaten away, then recycled back into the box only for his subsequent header to again be saved, Reid must have wondered whether it would simply not be his day.
With Paddy McNair, whose seven international goals were more coming into the game than the rest of Northern Ireland's starting side combined, also missing a free header and Eoin Toal striking the inside of the post before having a goal ruled out for a push, Michael O'Neill may well have started to think the same.
