I'm going to try something new this time. I'm going to look at some random positions from this book Combinations: The Heart of Chess by Irving Chernev which is a really, really old book - from 1960. I'm going to utilize my newly learned Javascript trick from last post, so under each position will be my proposed line and on the right will be the solution from the book. So let's get started and see where it takes us.
White to move. Gereben-Troianescu 1951
1q3r1k/1br1bpnp/pp2p1p1/2n1Q1P1/2PN1PBP/1PN5/PB6/3RR1K1 w - - 0 1
Show/hide my solution.
I have a feeling there is something more here. 1. Nxe6 {threatening checkmate} Nxe6 2. Nd5 {uncovering the bishop to threaten mate on g7 and attacks the rook} f6 {attacks the queen to save both the rook and mate 3. Qxc7 Qxc7 4. Nxc7 Nxc7 5. Rd7 Bd8 6. Bxf6 Bxf6 7. gxf6 Rxf6 {can't allow gxf7+ picking up the rook} 8. Rxc7 and white has a dominating position and is up the exchange.
Note: Rybka analysis reveals Nxe6 as a mistake that loses a 4 pawn advantage; suggests 2 ... Bxd5 as the newly placed knight on e6 is guarding the mate, so 2 ... f6 would not be played.

1. Nd5! {Attacks the rook and cannot be taken as it threatens 2. Qxg7+! Kxg7 3. Nf5+ Kg8 4. Nh6#} 1 ... Rfc8 2. Nxe6 {threatens mate on g7} Nxe6 {the one that's not pinned, of course} 3. Bxe6 {renews the threat} Bc5+ 4. Kh2 fxe6 {covers g7 with the rook on c7} 5. Nxc7 Rxc7 6. Rd7! {Gangs up on the pinned rook and blocks its control of g7. Looks like black is forced to give up his queen e.g. Rybka: 6 ... Bf8 7. Rxc7 Qxc7 8. Qxc7} 1-0
Ok. Maybe I should try an easier one. I will flip to the chapter called "Simple and Pleasing".
White to move. Tarrasch-Amateur 1919
1R6/2p5/Rnk1p3/1pppP3/1P6/2P5/2K5/7r w - - 0 1
Show/hide my solution.
OK. This one is easy. 1. bxc5 {attacks the knight} Kxc5 2. Raxb6 cxb6 3. Rc8#
Show/hide the book's solution.
1. bxc5 Kxc5 2. Raxb6 cxb6 3. Rc8# Woohoo! Irving was right, that was simple and pleasing.
Note: Rybka gives the line 1. bxc5 Kxc5 2. Raxb6 c6 as cxb6 leads to mate. Here black is down a whole rook and will ultimately lose.
Aside: Funny Honda commercial involving chess.
