Jessica Ennis admits she is hoping to score a psychological advantage over heptathlon rival Tatyana Chernova before London 2012.

Ennis has allowed herself to temporarily avert her focus from this summer's Olympics to concentrate her attentions on the defence of her pentathlon title at the World Indoor Championships in Turkey next month.

Ennis will come up against world champion Chernova for the first time since the Russian denied her gold at last summer's World Championships, and she is keen to avenge that defeat before the Olympics.

"All the time now I am building towards that meeting with Chernova in Istanbul," Ennis said in The Times. "I am not focusing on any one person, but it will be good to go there and score a psychological advantage.

"Athletics is a sport where you can affect your own performance, but start beating people and it gives you confidence. It will also be interesting to see how she copes with being the world champion. I'd love to go there, score a PB and defend my indoor title, but London is where I want to be at my best."

Ennis, who is competing at the Aviva Indoor UK Trials in Sheffield this weekend, insists she does not dwell on her disappointment in Daegu, and believes it will only spur her on to victory in London.

"That competition was just one of those things," she said. "It was one of those events where everything came together for her. Of course, I was disappointed, but you need the ability to move on in sport. This year is more important. I will now face Chernova in the pentathlon at the World Indoor Championships next month and then it's the big one. That's when everything has to be right. The rest is just warming up.

"I certainly do not obsess about my rivals and I am not fixated on the past because that is a waste of time and energy. Whenever I think back to the World Championships, when she pushed me into the silver-medal position, I use it as a positive. There is no self-pity, just motivation and the knowledge that I want to be the No. 1 again. It is there in the background, but it is not something that festers away at me."
