Run round putting out fires for forty moves then if still alive win the endgame with the queenside pawn majority!
How do you intend to decline the gambit? 1.d4 d5 2.c4
2...c6 Slav complex
2...Nc6 Chigorin's Defence
..... c5 Tarrasch Defence
c6 Semi Slav (Stonewall Dutch by transposition, Marshall Gambit, Abrahams/Noteboom Meran Defence, Botvinnik Variation and so on.
.... Nf6 The QGD complex featuring the Cambridge Springs, Orthodox QGD, Lasker and Tartakover and Swiss Defence variations plus many "sidelines" and transpositions into lines above, and we haven't brushed the 3...Be7 lines yet.
You have asked a very big question. You will be told that "The QDG is boring, and gives Black no winning chances" despite the fact that almost all the world champions have played it in critical matches. You will be told that "The Tarrasch gives freer play for your pieces, but leads to a slightly worse endgame" because that is what it says in MCO after Kasparov toyed with it 20 years ago; or "The exchange variation leads to a strong minority attack for white" because that is what it said in instruction books that all the 60 year olds read and have regurgitated since. Most average club and internet players lack the skills to replicate those verdicts even if they are true at top level.
The best thing to do is decline the gambit a few times, try to defend the threats you can see, form a plan to counterattack White's centre, and see how it goes. Can you find good piece placements easily or do you feel restricted and cramped. Are your opponents putting you under too much pressure or do find the positions solid and secure. Do you go to those games first in your play list or do you leave them to the end and dither? This will be the best guide to how you feel about an opening before you get into the specifics of individual moves, move orders and ideas. Those will then be dictated by the accuracy of the opponent's play as you progress through the levels...
