Thistle boss Stuart Davidson is urging his players to pull out all the stops this Saturday for their Macron Scottish Cup third round encounter with Shotts Bon Accord.
After an encouraging start to the Premier League, Largs are hoping to go on a good run in the national tournament for the first time in several seasons.
Indeed, it was Shotts who ended Thistle's last good run to the semi-finals in 2012, winning at Barrfields Park on penalty kicks.
There is plenty of incentive going into the game this weekend, against a team managed by John McKeown, who led Cumnock to the first division title after pipping Largs on the last day of the season two years ago.
Davidson himself has a special affinity with the tournament as a two times winner as a player, scoring a late winner for Auchinleck against Clydebank in the 2009 final in a man of the match display.
He said: "The cup is massive for us.
"The tournament is always special as it has a real history to it and it brings a different buzz if you get far into it, and it keeps the dressing room high.
"As a former winner, it means a lot to me and it should mean a lot to our players as we want to get as far as we can.
"It gives you good memories, and things you can look back upon.
"Over my career, I have played a tonne of league games, but it is the big cup games that you remember if you have done well.
"The Scottish Cup is massive for us, and hopefully we can get a good crowd to back us."
And a former Largs Scottish Cup finalist in Eddie Walton is going to be helping Davidson in terms or providing a report on the opposition after his side Port Glasgow drew with Shotts on Saturday.
Bon Accord are sitting in second position in the West of Scotland third division, and even their goalkeeper scored from a kick-out against Glasgow Perthshire in a 4-1 victory the week before.
Davidson said: "To be honest I don't know much about their players but I am sure they will be well organised under John McKeown.
"People might look at the gap of two divisions, but I can assure you that we are not thinking about that, and we are expecting a tough game, and we will need to be at our very best, nothing less, to ensure we get into the next round."
And Thistle may have a former Scottish Cup winning ace up their sleeves going into the game.
This is because Iain Fisher, who won the cup with Beith in 2016, is back training at Thistle after leaving over the summer due to work commitments.
Davidson confirmed that Fisher was back training with Thistle, and asked whether he could feature against Shotts, replied: "You never know!"
Thistle are looking to the Scottish Cup for some succour after the disappointment of a 3-0 reversal in Glasgow against Clydebank.
Davidson said: "Clydebank started the game really well and before we knew it we were two goals down before we got ourselves together.
"We started a bit lacklustre and they took advantage.
"I don't think we can use their park as an excuse - we good good results on the road last season on similar pitches, we just need to roll our sleeves up and muck in - we didn't do that.
"However, I will give credit to the players, they got themselves back into the game and were competing and defending very well.
"There were chances in the second half, but nothing really dropped for us, so credit to Clydebank as they deserved the win.
"When we asked them questions, they defended well. They then got a third goal and that sometimes happens when you get a bit desperate.
"There were some positives and we were up up against a good team sitting second in the Premier. 
"It was disappointing how the goals happened but the players know that, and it was certainly uncharacteristic of our play recently."
Davidson also had some choice words with whistler Gary Logan at the end of the encounter.
He said: "I accept that it was our own fault for the goals but I felt the referee never gave us anything on the day.
"You are trying to get back into the game but it was our players who were getting bookings, and not there's, and all I am calling for is a measure of consistency.
"Everything went Clydebank's way in terms of the decisions.
"Despite this disappointment, we are hoping to bounce back in the Scottish Cup, but we need to be at our very best to come through it."
