Boekbespreking De Loper door Johan Hut

Johan Hut heeft een boekbespreking aan De Loper gewijd. Zie hier onder:

Een boek vol stoere lopers

Bij uitgeverij Tirion verscheen deel 4 uit de serie ‘Wij presenteren’, van Hans Böhm en Yochanan Afek, over de stukken van het schaakspel. Na de pion, de toren en het paard is nu de loper aan de beurt. In het geschiedenisverhaal, waarmee de schrijvers traditioneel beginnen, vertellen ze dat de loper in diverse culturen eerst olifant, vaandeldrager, nestor, lijfwacht en bisschop was. In het Engels heet hij nog steeds ‘bishop’, in het Frans ‘fou’, oftewel dwaas. Dwaas is hij in het boek zeker niet en ook niet zo zwak als in vroegere eeuwen, toen hij slechts zes velden tegelijkertijd kon bestrijken.

De schrijvers behandelen weer vele thema’s, zoals lopers tegen vrijpionnen, lopers tegen dame, pat, de lange diagonaal, lopers op paardenjacht, lachende lopers, promotie tot loper en inspiratie door wereldkampioenen.

Cheerful Pieces 

Max Euwe Square, in the heart of Amsterdam, prepares for the Christmas and New Year festivities. Giant illuminated chess pieces are hanging on top of the pubs and cafes there. Here I enjoy this cheerful view just before entering Casino Holland where the presentation of our new book De Loper took place last night. A lovely decoration to  the  series of books on the different pieces!

The Agile Bishop in Action

The fourth part of the Dutch series by your truly and Hans Böhm is just out: “Wij presenteren De Loper” (We present the Bishop) young brother to De Pion, De Toren and Het Paard. Following an historic review of the piece in question, the special qualities of the Bishop are demonstrated through 60 instructive chapters, comprising four examples each. The 240 positions are derived from the very best of over the board practice as well as from the fine art of the endgame study. This was Bobby Fischer’s favourite piece and four of his most memorable combinations were highlighted by magnificent bishop sacrifices and they can be found in the book alongside the masterpieces of other world champions. Other classics of the greats display typical Bishop Manoeuvres such as the Greek gift, the Boden mate and the double bishop sacrifice to name just a few. A number of chapters show the agile Bishop successfully coping with any of the enemy pieces, including the mighty queen or even with a pair of rooks. A great deal of the examples are classical endgame studies by the best composers of all time, demonstrating paradoxical motives such as the “wrong” bishops and opposite colour bishops winning against all odds and despite material inferiority. Various examples deal with the unique geometric traits of the Bishop in the battle on crucial diagonals, symmetry and asymmetry, the struggle against promotion. Other chapters display the role of the Bishop in more common topics such as stalemates, fortresses, underpromotions, zugzwangs, positional draws, perpetual check and systematic manoeuvres. The closing chapters display the smiling Bishops in chess jokes and funny puzzles and for the first time a couple of curious Bishop Moves from the practice of the …authors!  

All examples in the book are presented for solving too; training and enjoying are offered for the same price even for those among us who cannot read Dutch as chess is in fact a universal language.

An Invisible Escape

My game against Frank Erwich from the last round of Eijgenbrood tournament reached the following charged position:


  White to play

The game continued 42.Qxe2 Rxe2 43.Bxg6 hxg6 44.Rh4 Rd2! and Black eventually converted the Rook ending. Later on, in home analysis with the help of the silicon monster, I discovered a fantastic salvation line for White in the diagram position. Give it a decent try before checking the solution in the PGN file.
