Nottingham Forest manager Sean O'Driscoll believes two watching briefs were the secret to his team snapping a five-match winless streak.
O'Driscoll saw bottom side Peterborough's two previous matches in which they had won at Hull City and Barnsley. and he was a happy man after a stunning strike from Republic of Ireland international Andy Reid ensured Forest didn't join the Posh casualty list.
That contribution arrived moments after Forest keeper Lee Camp had pulled off a world-class save to keep out a fine header from Posh hitman Tyrone Barnett.
O'Driscoll said: "Watching Peterborough in their previous two games was really valuable. I always like to watch opponents in person if at all possible. You get a much better feel than from a DVD.
"Both Hull and Barnsley became really frustrated with Peterborough who play with what is almost a 10-man defence at times. I sensed that was happening to us as well late in the first half so half-time came at a good time.
"And we obviously scored a very good goal. I kept thinking 'God, don't shoot' as Andy ran forward but he did shoot and it was a great strike. Not a lot has gone for us in recent games so this is a confidence-boosting win."
Forest hitman Simon Cox was denied by Robert Olejnik in a first period of few chances but the clash burst into life after the break. Camp produced an excellent save from Michael Bostwick before pulling off an even better stop seconds later when keeping out Barnett's goalbound header.
Reid's breakthrough arrived just as Forest appeared to be on the ropes but the visitors would have won far more comfortably but for the heroics of Olejnik later in the match.
Posh boss Darren Ferguson said: "Losing that game is a really hard one to swallow because there is no doubt in my mind we deserved something out of it.
"I did fear there may be trouble when their lad ran with the ball and so it proved. We had worked on not allowing their better players to have the ball high up the pitch, but unfortunately we didn't manage to cut it out in that situation. Their goal came in our best period of the game. We were really turning the screw at that point."
