They played four matches on four boards, dominating in each match for a clean sweep.

Consisting of Sam Kobelke, Marlon Dutlow, Jack Shoobert and Harry Freudenstein the team are aiming for nationals in Melbourne later in the year, something they achieved in 2017.

Sam Kobelke began playing "serious chess" in year six, and explained exactly what serious chess means.

"Playing seriously is knowing all of the strategies and playing in competitions," he said. 

"I've played in about seven now. My strategy is to trade pieces so there is less on the board and that seems to work well for me."

Marlon said he likes to open on the queen side and control the centre of the board. 

"I take out pieces with my queen and go from there," he said. 

"Mr Battiston (chess coach and teacher) is really good pushes us a lot. The win at Grafton was really satisfying."

Jack Shoobert, who is use to the now graduated older sister Michelle playing alongside him, has been playing since year two.

"We're aiming to win the next event and make it to Sydney for the final, and after that we'd like to go to Melbourne again," he said.

Cheryl Hyde, teacher and chess team manager said they must come in the top five schools to qualify for the nationals.

"We're hoping to be able to get ourselves there again this year. The team performed exceptionally well last year," she said.

"Marlon didn't go last year so it would be great for him to attend. We'd love to go again and better those personal bests from 2017 set by Sam, Jack and Harry."

Harry is the highest ranked player in the team just ahead of Jack, and will be the most experienced when the school heads to Armidale for a day-long tournament next month.

"We're taking a compliment of ten students, with everything from beginner players to the top players," Mrs Hyde said.

"It's very much a mental sport. The students are doing really well and we are really proud of them. They take it very seriously and are great ambassadors for the school."
