my fourth competition game

this game was a good one. i played with precision. the game was in the queens gambit declined. i waited untli his mistake and got the upperhand. was i able wo win?

lets talk about the queens gambit declined first. a very dinamic play in the queens gambit that arises after the moves 1.d4,d5 2.c4,e6 3.nc3,nf6 in the exchange veriation 4.cxd5 there are two plans avileble -

• 4. Nf3 - This is the solid classical option.

• 4. Bg5 - Since this move is usually played anyway, it is both constructive while keeping options open.

now this is the game-
