A goal by debutant Tomas Necid capped a good night for the Czech Republic who moved up to second in their World Cup qualifying group with victory against a resilient San Marino side.
However, it took the Czechs until the 47th minute to break the deadlock through Radoslav Kovac but they doubled their tally six minutes later thanks to Zdenek Pospech.
Necid came on for his debut in the 66th minute and the promising teenager opened his international goalscoring tally seven minutes from full time.
The Czechs move to second in Group Three, above Poland and Slovenia on goal difference and two points behind Slovakia, while San Marino remain rock-bottom with no points from four games.
The visitors were without goalkeeper Petr Cech after the Chelsea stopper was ruled out with a leg injury.
Anderlecht's Daniel Zitka was deputising between the posts but he was rarely tested by a San Marino side who had only scored one goal in their World Cup qualifying campaign.
The tiny republic have conceded nine goals in those games and almost got off to the worst possible start as the visitors should have taken the lead with less than a minute on the clock.
Almost straight from kick-off the Czechs stormed up the pitch and Jan Polak put a good cross into the area which Martin Fenin fired just wide.
Having survived that early scare, San Marino were camped out in their own half and the visitors found it hard to get a sight of goal.
They came close to taking the lead in the 23rd minute but Milan Baros headed Libor Sionko's corner inches over the crossbar.
The Czechs were laying siege to the San Marino goal and a beautiful move on the half-hour mark should have put them ahead but Tomas Ujfalusi's effort from just outside the area brushed the top of the crossbar.
San Marino would have been delighted to go in at the break on level terms but Czech Republic coach Petr Rada must have been fuming that his side had not taken the game by the scruff of its neck.
Whatever Rada said to his players appeared to work as they scored two within the first eight minutes of the second half.
A goalmouth scramble less than two minutes into the second half saw Polak's free-kick fall to Kovac who fired his side into the lead.
The visitors doubled their advantage six minutes later when Kovac released Radek Shirl whose cross was cleared by the San Marino defence but only as far as Pospech outside the area who fired a stunning thunderbolt into the top corner.
They almost extended their advantage still further on the hour mark but San Marino goalkeeper Aldo Simoncini pulled off a great save to deny Fenin a certain goal.
The Czechs did have the ball in the back of the net again five minutes later as Baros rushed into the area to fire Pospech's cross home, but the referee adjudged the cross to have gone out of play and ruled out what would have been only the striker's second goal in 14 internationals.
However, the visitors did get the goal which would lift them to second seven minutes from time as Necid slotted home from the centre of the area to celebrate his debut in style.
The 19-year-old almost grabbed a second in injury-time but his effort scraped the top of the crossbar.
