Portsmouth and Plymouth could not be separated after sharing four goals in an eventful first leg of their League Two play-off semi-final.
Marc McNulty gave Portsmouth an early lead when he found space on the edge of the box to fire past Luke McCormick.
Argyle soon levelled as Jamille Matt headed in and then spectacularly put his side ahead with an overhead kick.
Gary Roberts’ second-half penalty brought Pompey level after Peter Hartley tripped McNulty in the area.
The two sides will meet again in the second leg at Home Park on Sunday for a place in the Wembley play-off final on 30 May.
Fleetwood loanee striker Matt looked to have grabbed the headlines in stunning fashion with his two early goals for the visitors.

He had happy memories of Fratton Park even before kick-off having headed the first goal when Derek Adams’ men beat Pompey 2-1 last month.
But, the 26-year-old was arguably fortunate to still be on the field when he netted his acrobatic second goal from a Kelvin Mellor long throw.
An apparent off-the-ball incident involving him and Portsmouth captain Michael Doyle did not result in any punishment being dished out by referee Oliver Langford, but did lead to dismissals on the touchline.
Following consultation with fourth official Gavin Ward, Portsmouth manager Paul Cook and Plymouth assistant Paul Wotton were sent to the stands after a heated exchange.
An explosive opening to the tie was perhaps to be expected between two sides who were only separated by three points and one place in the regular season.
Portsmouth deservedly levelled six minutes after the restart as Roberts placed his penalty beautifully into the top corner.
But, another questionable decision from referee Langford saw Plymouth centre-back Hartley only receive a yellow card when he appeared to be the last man when stopping McNulty’s run into the visitors’ box.
