Is the Portuguese Gambit playable?

I think that 3.Bb5+ is better than 3.d4

In my opinion it is fully playable, although you should be familiar with the themes and be good with tactics.

A wise man once said if you sacrifice your queen, sacrifice one rook as well.

A wise man once said if you sacrifice your queen, you will probably lose.

White should simply play 3 Be2 in this line . 

It is still fully playable for black, white only gets a minimum advantaje from the opening whit Be2.

Look in your database for a game between GM Daniel H Campora and IM Rui Damaso , they played this line with 3 Be2 and it was an interesting game . Damaso is a well known specialist in the Portuguese variation . 

The one I got is 3Bb5+, and after Nd7 4Be2. That is a more annoying order because the knight ends in a worse position, but it´s still playable. I´m not sure if it is the same game (year 2000).

And, just to be clear, I´m not saying that the portuguese is the best defence, I just say it is a sound one (check 365chess database, 34% wins by black). I used to think it was nuts, but I read the Selby book about it and started to play it with great results.

Can you tell me the year and tourney ? It was a tourney in Portugal I believe but I dont recall the year ... 

I believe GM Campora won the game .
