Boston Town inched further away from the drop zone with this valuable draw.
In fact, home fans came away frustrated that they hadn't managed to win a game in which they created most of the best chances.
Jordan Nuttell put the Poachers ahead with an impudent piece of opportunism after 11 minutes, pouncing on a defensive error to race clear of the Rothwell back line, round the keeper and slot home from a tight angle.
But Boston faded after their early brightness and couldn't complain when mid-table Corinthians levelled shortly before half-time.
It was much more one-sided after the break, with the hosts belying their lowly league position with periods of sustained pressure. Richard Ford saw a header dribble agonisingly wide after he had drifted into space from a free-kick and there were also chances for Nuttell to add to his tally.
Nuttell and the returning Aaron Eyett increasingly caused panic in the visiting defence and the influential Michael Hardy immediately made an impact when he came on as a sub. Indeed, he came close to scoring when a well-struck overhead kick was smartly saved.
Boston suffered a blow when newcomer James Tricks was sent off for a questionable second yellow card in a game littered with needless bookings.
But Town continued to press forward and finished strongly to make it three unbeaten games and edge further ahead of Harrowby, who were annihilated 9-0 by Holbeach.
Town: J Lambley, L Lambley, Forth (Howitt), Ashton, Field, Ford, Eyett, Maddison (Hardy), Nuttell, Tricks, Revell (Farago)
