Recognise the Pattern # 37

This article aims at beginners only. Here are some positions on a typical theme. You are advised to find the solutions first and then look at the theme name and the solutions:

1. Bill Wall vs Robert Gantt 1978
White to Play

2. Eduard Hamlisch vs NN 1899
White to Play

3. Shmatkov vs Eidlin 1960
White to Play

The theme is ‘sacrifices on f7/f2 against uncastled king’. Of course the main idea is to keep the opponent’s king in the center but often it is used to win/trap opponent’s queen in conjunction with mating threats. I thought I have covered this with my series on recognising the pattern, but it was missed out. Recognising the pattern is a series where I have discussed typical checkmate patterns, attacking formations and endgame patterns.


Solution 1:

1.Bxf7+ Kxf72.Ng5+

Black resigned in view of Ne6 in case of Kf8 or e8 and Qc4+ in case of Kg8.

Solution 2:

1.Bxf7+ Kxf7 2.Ng5+

Black resigned in view of Ne6 in case of Ke8 whilst Kf6 can be met by Qf3#.

Solution 3:

1.Bxf7 Kxf7
2.Ng5+ Kg6

If 2… Kf8/e8 then Ne6 wins the queen or if 2…Kg8 then Qb3 wins.

3.Qd3+ Kh5

If Kh6 then Ne6 discovered check wins queen.


This wins due to the threat of winning the queen or checkmate with Qh3.
