The author of this book Herman Grooten is an International master and has taught players such as Loek van Wely.

At the start of the book Grooten emphasises that many chess players memorise lots of opening theory but it does not improve their results as they do not understand the position when their opponent deviates from theory.

He explores the various pawn structures in variations of openings in the Ruy Lopez (Spanish Game) and (Giuoco Piano) Italian game.

The first variation he looks at is the so-called Berlin wall (Berlin Defence) which was used very successfully by Vladimir Kramnik in his World Championship match vs Gary Kasparov.

Knowing Kasparov was a great attacking player Kramnik chose a variation which leads to a Queenless middle game.
Although Black ends up with doubled pawns on the Queenside (as in the Ruy Lopez, Exchange Variation) his bishop pair is good compensation and his doubled pawns are not weak and easily exploited.

Grooten then shows what each side should be trying to achieve to progress their position.

In the Open Lopez the pawn structure is very different : White has a four to three pawn majority on the kingside and with a pawn on e5 and good use of the d4 he has good chances for an advantage and it is well known that Viktor Korchnoi played the Open Lopez in his famous match with Anatoly Karpov. Black has a four to three majority on the queenside but his c7 pawn is backwards and weak. If Black can play c5 then he will probably equalise but he normally cannot afford to play Nxd4 as after cxd4 his c7 pawn is very weak.

Next Grooten examines variations of the Closed Lopez where play typically goes 5 Be7 6 Re1 b5 7 Bb3 00 8 c3 d6 9 h3. Here the Zaitzev 9…Bb7 Chigorin 9…Na5 and Breyer 9…Nb8 are explored in detail. In all three of these famous lines the pawn structure is the same White pawns on c3 d4 and e4 Black pawns on c5 d6 and e5.
White normally can decide the structure by either playing d5 or d4xc5 or maintain tension with Nbd2 when Black can change the structure with c5xd4,
Paul Keres often did this in the Chigorin Variation.

Grooten looks in depth at the theory of the Two Knights where White plays 4 Ng5 including some variations in the main line 5 Na5 which I have not seen before and maybe are unusual and interesting.

Finally, He also looks at some interesting world class games the best of which is a win by Paul Keres over Mikhail Tal as Black in the Chigorin Variation.

In summary, this excellent book will appeal to club players who know these openings but are not sure what plan(s) to adopt in the consequent middle game.
