And despite falling just short of a repeat in the final, he said: "I'm happy with how I played. I missed doubles, though, and he punished me. He (Adams) was world class and just didn't miss much."
Chisnall showed few signs of nerves with two 180s and a 12-dart finish to take the opening leg, but his inexperience betrayed him throwing for the set when he had three darts at double five, maxed out, and allowed Adams to steal.
The doubles continued to elude the St Helens player in the second and third sets as well and it looked like he was staring down the barrel as Adams strolled into a 3-0 lead.
But "Chizzy", as he has all tournament, dug deep. He brought up his first set of the final with an 84 checkout and then watched on as Adams followed a 10-dart leg - the leg of the championship - with three missed darts at double 16 to allow him to pull it back to 3-2 with double top.
It was the match of my life - Adams
Victory in the final set before the interval would have completed the Chisnall comeback, but England skipper Adams produced a stunning 170 checkout on his way to restoring a two-set cushion.
That was immediately cut back to one as Chisnall held his throws in set seven to make it 3-4.
And despite missing outs in two legs to break Adams in the eighth, he levelled after Adams missed three darts at 17 to take the set.
Any assumptions that the momentum was with Chisnall, though, were put firmly to bed as Adams regained his lead with a whitewash set next up and then fought back from two legs down to win the pivotal 10th.
Somehow, though, Chisnall again clawed his way back, holding his throw in the 11th, and then breaking courtesy of a couple more 180s in the first leg of the 12th to set up a chance to level at 6-6.
It was not to be, though, as Adams visibly broke his opponent's spirit by breaking back in the second leg.
And even though it took him four darts to hit the crucial double top, the 53-year-old was not to be denied his moment after an absorbing 139-minute encounter in front of a vociferous crowd.
He ended the match with a a 31.67 average, four 180s and five 100-plus checkouts, with Chisnall boasting a 31.14 average and three 100-plus finishes.
