I've began going through, over the board, 1001 Winning Chess Sacrifices and Combinations - 21st century edition. This book is a great supplement to my last question on studying tactics, and I feel like I'm learning a lot from it.
One of the problems I'm having with this particular book is right out of the gate the tactics for pins are very difficult to see in a lot of cases for me. Here is an example, problem 14:
[fen "r4rk1/p2nqppp/Qpp5/3p4/3Pn3/2N1PN2/PP3PPP/2R2RK1 w Qq - 0 1"]
To me one move was clear -
This move clears the way for the rook to enter and pin the knight to the queen. It's almost forced to take with the pawn to prevent the queen capture, the queen is on a pretty good square all things considered. Initially I had evaluated:
But disregarded it as a first move because even though the knight is pinned to the queen
- ... Rfb8
Mitigates the attack immediately and forces the queen back - or so I thought. By having the rook perform the pin I'd be in better shape to mitigate that attack when I do 2. Qb7.
- ... Rfb8
- Nxd5 Rxf7
Which seemed too easy to be right for this tactic and leaves the game at even money, which from what it seems is never the goal of a pin.
So from what I've gathered here I saw the pin at least. The problem I'm suffering from at the moment is how the solution plays out - the solutions don't really give great justification and there's a lot of moves here to consider it "solved":
- Qb7! Rfc8
- Nxd5! Qd6
From this I'm curious
- Why 1. ...Rfc8 and not Rfb8, attacking the queen?
- Why does black resign after Rxc6!!?
- How do I study from this tactic book effectively? I'm getting a ton of them wrong even though I'm seeing the tactic, I'm unable to make the same moves in the tactic for black to make everything "play out right". I'm not sure when to consider a solution "complete".
I'm sorry if this is trivial, I'm working on fixing my over the board play by doing tactics and this book is incredibly difficult. Difficulty is great because its challenging but I'm only on problem 14!
