Motherwell could clinch one of the two places on offer in the Clydesdale Bank Premier League this weekend and Ross County's 2-2 draw with St Johnstone last Sunday left third-placed Inverness in a strong position.
"If we can keep it tight between Dundee United, St Johnstone, Inverness and ourselves, it will be an interesting finish to the SPL campaign," Adams said.
Caley Thistle are four points in front of Saints ahead of their trip to Perth on Saturday, with County a further point adrift.
But Ross County can put the pressure on their Highland rivals by beating Dundee United in Dingwall on Friday night and Adams is determined to stay in touch with Inverness ahead of the derby on the final day of the campaign on May 19.
Adams added: "It's great that we talk about it in that way, but Inverness have had a fantastic season - it looks like they will win the race to play in Europe next season.
"But if we win on the Friday night then it puts a lot of pressure on them going to the Saturday's game."
County go into the game two points ahead of United but they have not beaten their Tayside opponents since the first competitive meeting between the teams 15 years ago.
Adams, in his first spell at the club, scored twice in a League Cup win but County have since failed to come out on top on 10 occasions.
"We have played well in spells against them, but we have found it difficult to win against them," Adams said.
