Play-off chasing duo Brighton and Middlesbrough shared the points in an entertaining draw at the Amex.
Brighton's Adam El-Abd had hit the post before Marvin Emnes flicked in Barry Robson's corner at the other end.
Lukas Jutkiewicz came within a post's width of doubling the lead, before Inigo Calderon met Kazenga LuaLua's corner with a powerful header to level.
Jason Steele palmed away Sam Vokes' header to guarantee a point for Boro, who have now not won in six games.
Tony Mowbray's side were fortunate not to be behind in the first half as Vicente's deflected free-kick dropped just wide and El-Abd hit the woodwork from Will Buckley's corner.
But Emnes caught the previously impressive Brighton goalkeeper Peter Brezovan out of position with a deft touch at the near post to grab the opener.
Brighton got the goal their performance deserved, however, when Calderon planted home a header at the far post.
Both goalkeepers were kept busy until the final whistle but neither side could conjure a winner.
Brighton boss Guy Poyet: "It was a great game of football, very difficult for both teams and it shows we can compete.
"The longer we stay in the top six the better. There were nerves all over the place, but we are still in there so we can't complain.
"It shows how far Brighton have come and that is the key. We need better performances away from home but we are there. We deserve to be in the top six.
"We are getting closer and the players are coping well. We were not dominant in this game, but we had the best chances and competed against a very good team."
Middlesbrough manager Tony Mowbray told BBC Radio Tees:
"With four weeks to go it is very tight obviously, but we have to keep going.
"We've drawn four in a row now and it's a very tight league. With six games to go, we'll have to win two or three of them to cement a place in the play-offs.
"But credit to Brighton. Their psychology can only benefit football. Brighton play in a similar way to how Swansea played in the Championship last season."
