If a king is uncastled we all know that we have to open the lines against it, especially those of major pieces. Sometimes your opponents are so friendly that they don’t castle for personal reasons :), but sometimes there are some tough guys who are not so friendly and there you have to demonstrate your skills. Here are two interesting examples with which to check your skills:
Samsonkin against Nakamura in 2009
Q:- In a given position, Black needs just one move to castle. Can you trick Nakamura?
A:- In the game White started to press a follows:
1. f5! e5??
1…Bf6 was a good alternative but everybody makes mistakes! After 1…Bf6 2. Be3 e5 all three results were possible.
2.Ne6!! fxe6 3.Qh5+ g6 4.fxg6 Nf6 5.g7
Nakamura fought for next 11 moves and surrendered.
Steinitz against Bardeleben in 1895
Q:- How could you force Black king to relinquish his right to castle with a series of forced exchanges?
A:- I could do it as follows:
If 1.Bxe7 then N6xe7 2. Qb3 and castles
If 1…Bxg5 then 2. Bxe6 – fxe6 and d5 is crushing.
2. Nxd5 Qxd5
If 2…Bxe7 then 3. Re1+ Be7 4. Nxe7 – Nxe7 and Qe2 and Black can’t castle.
3.Bxe7 Nxe7 4.Re1 f6 5.Qe2
And Black can’t castle.
