White is a pawn up and we will consider thiswhen we create TO DO LIST:- trade the queens and the bishop from a6which stops the free pawn- threatening to promote the pawn will force theblack rook to take a passive position on a6- approach the king in order to create piecesuperiority on the queenside- avoid massive pawn trades or a Black's freepawn on the kingside- if it's the case, give up the a6 pawn reaching awon pawn-endgame.

White has a small edge due to:- queen side pawn majority (where White cancreate a free pawn)- better pawn structure (no obvious weaknesses,while Black has a7 and f7)- Nb5>Na6.

TO DO LIST:- restrict black pieces activity with b2-b4 (Na6)and g2-g3, f2-f4 (Bh6)- ...and, at the same time, fixing black weakpawns on f7, e6, f5- keep Black's rook passive on the 7th rank toprotect a7- improve knights' positions, trying to reach theideal foreposts d6 and e5

23.b4!RESTRICT FIRST, GRAB LATER

[ 23.Nxa7 Nc5Suddendly, all Black's pieces became veryactive; the counterplay is based on the firstrank weakness: Rd8-d1, Nc5-d3 and Bh6-c1. ]

Tilburg 1991[solution]

(Diagram)

White has just exchanged the dark-squarebishops creating a weak square complex aroundthe black king. White is also dominating "d" fileand the 7-th rank but for a win, TO DO LIST isnecessary:- emerge with Rd1 on the 4-th rank defendingc4 and e4 (releasing the queen from defendingit and avoiding queen-trade) which also createsa piece superiority on the king side- force Black to push the h7 pawn, leaving g6weak- defend g2 in order to bring Nf3 in attack- threat to double the rooks on the seventh rank

28.R1d4 Rae8 29.Qf6+According to our TO DO LIST, even better was:

21...Nb6Which are the CQS of Black's last move?Black is threatening Nb6-c4 and b5-b4 to trapthe Ba5. Is this a real threat? The answer is no,because a6 and b4 will be weak and the bishopcan escape after b5-b4 and Qb7-b5 on c7 or d8(depending where the black dark-square bishopwill be).

TO DO LIST:- push b2-b3 to stop Nb6-c4- allure Black to push b5-b4 in order to make thequeen side pawns, a6 and b4, vulnerable- prepare Nc1-d3 to take under control the darksquares b4 and c5- trade the dark square bishops- besides a6 and c-file, White must create a newweakness in Black's camp

The game continued: 22.b3 Nc8 23.Bf1 Bd6
