50.Bd4?
This mistake helps Shankland to release his bishop.
The correct move is 50.Rb7!! +- with the idea of trapping The Black's bishop by Kb5-Kc6-Bd4-Kd7.

Bacallao takes a risky plan. It would have been better to play 22...Bd8 23.Nc4 Rb8.

In this position, White has little control over the queenside – an area in which he normally places his hopes in the Queen's Gambit Declined. A transfer of his forces to the queenside seriously compromises the kingside, where g2-g4 has created certain commitments. For this reason, White will have to play on the kingside, and as Black has a dark-squared bishop it will most likely be on the light squares. All of this basic logic points us in the direction of the threat in the position. White will play 18 h4! and it will give him the advantage. Black should prevent this, after which he will have time to slowly improve his position.
17...b6?
(17...Bh4! would have given Black a better game, when it is not easy to see how White can improve his position, whereas Black has a lot of moves coming.)
18.h4! c5 19.dxc5 bxc5 20.Qxc5 Qxc5 21.Rxc5.

12.Qc3!
The point. Now Black has problems with both the dark squares and coordination. 12.Bb5 c6 does not seem to achieve anything as the knight is far from d6.
12...Nc6
After 12...e4 13.Nd4 Black still has problems with his development as c7 is hanging, and thus White has a small advantage. White wins a pawn after 12...Re8? 13.Qxe5!
13.Bb5
