Queen Gambit Decline - Trick only 13

The game start with 1. d4 d5 - Queen Pawn opening. Then 2. c4 f6, change to Queen Gambit Decline - Marshall Defense. This isn't an usual choice for black when play with Queen Gambit. Then White play Bf4 to control the centre. Black just want to defense so he play e6, actually dxc4 is better because it help black can both defense then counter-attack. White play Nf3 then. e3 is better, but Nf3 is also good because it help white to take control the e5 with both bishop and knight. Here black should play dxc4 because black haven't play e3 so that bishop can protect the c4 pawn. But here black play c5 to counter-attack. Black is to hurry to do that because white play e3 to protect d4 pawn, and also let white bishop protect c4 pawn. Black pay Nc6 - a good move help to take control the centre. White play Be2, let the king to castle, prepare for big war. Black play c6 - not the best move because in the following position, black should attack to have place for developing two bishops. White play Nbd2 help to protect c4 pawn.Black play Bb7 to develop the bishop. But it not the best move because it have a lot of risky when bishop in f4 take control the b8 square so that rook can't protect the bishop. White do the first plan, O-O to take the king inside. Black play Bd6, like to trade the strong bishop in f4. White play Bxd6, black play Qxd6, help to control the centre. White play cxd5, Black play Qxd5, want to take the queen to a good place, also with the help of bishop in b7 to attack the king, change from defend to attack. White play dxc5, black play bxc5. White play b3, but it isn't the good move because it a bit harder to develop the queen. Black play Ne5, take control the center, but also very tricky. White want to trade the strong Knight of black, so Nxe5 was played. This is the mistake that beginner often have. Ne5 also take knight to a good place, but also let the bishop help for the queen to attack the King from a8-h1 diagonal line. Black play Nxe5 let the Queen to g2 checkmate with the help of the bishop, after 13 moves play win with the simple checkmate.
