Try to figure out the solution to each of the five problems. Then scroll down to see each of the games in its entirety along with the solution to each problem. This can also be a useful article for those of you that open 1.d4/2.c4 as every game starts out that way and White wins all five games, although in one of them Black missed a win!
1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bc4 c5 8.Ne2 O-O 9.Be3 Nc6 10.Rc1 Qa5 11.Kf1 cxd4 12.cxd4 Bd7 13.h4 Rac8 14.h5 Nd8 15.hxg6 hxg6 16.Kg1 Ba4 17.Qd3 b5
This move allows Black to equalize with correct play. The main thing about this problem is to realize that White is already better and that there is no need to do anything fancy. The simple 18.Bd5! gives White the advantage. The open h-file isn't going anywhere. White's Bishop is also ready to go to h6 to contest the fianchettoed Bishop. With the safer King and with most of Black's pieces either on the Queenside or completely bottled up, White's better.
The position is equal after 18...bxc4 19.Qh3 (19.Bxa5? cxd3 20.Rxc8 dxe2 is better for Black) Qh5 20.Qxc8 Qxe2 21.Qh3 Qh5 22.Qxh5 gxh5 and now 23.Rxc4 or 23.Rxh5 are both considered equal, though admittedly, I would rather have White as his position appears to be much easier to play.

Sure this wins, but it is not White's best move. The correct answer is 34.Rc1! This move forces Black to either surrender the c-file to White, or else surrender the a-pawn, putting him down two pawns. After 34...Rc7 35.Rfc2, the open file is White's. If instead 34...Qc5 or 34...Qc7, then a trade on c3 can be followed by grabbing the a-pawn.

There is no way for Black to stop the c-pawn following this Queen sacrifice. White will immediately win the material back and then some.

In severe time trouble, Black buckles. Black is absolutely crushing White after 45...Qh2!!. For example, 46.a6 g3 47.Rb2 Qxb2 48.Rxg3+ Bg4 49.a7 Qa1+ 50.Kg2 Qxa4 51.Qf1 Qxa7 and White's busted.

White tactically wins at least a pawn with this move.

Or 16...Rf5 17.a3 Bd6 18.Rfd1 Bc7 19.f4 Rff8 20.b4 followed by 21.fxe5!
Or 17...Qc7 18.c5 and White gets the piece back.
