FACULTAD AGRONOMIA:

In document D I R E C T O R I O No. 14/2001 (página 72-82)

A battle of a queen against two rooks is always sharp and complicated. Two rooks are said to be slightly stronger than a queen, but the correct assessment depends on a situation on the board. As a rule, tactical players prefer to have a queen whilst posi­

tional players prefer two rooks.

13.1 QUEEN IS STRONGER THAN TWO ROOKS 13.11 Creation of mating threats

If the defender's pieces are passive, the stronger side's queen, king and pawns can weave a mating net.

A queen lends effective support to passed pawns. A passed pawn sup­

ported by a queen is able to tie both the opponent's rooks, whilst at the same time the queen can exert pressure all over the board.

13.2 SUCCESSFUL BATTLE OF TWO ROOKS AGAINST A QUEEN

In these endings the decisive factor is the coordination between the rooks. The best situation is when the rooks are doubled either on the penultimate rank, or on the b- or g-files, with the opponent's king being cut on the edge of the board.

White's plan is typical for positions of this type: 1 ) to attack the f7-pawn twice, thus forcing Black to advance it; 2) to double the rooks on the 7th rank; Black will have to defend passively; 3) to transpose into a won pawn ending .
