B) Subtle Technical Moves
Before implementing your real plan, it is often
worthwhile to probe with a preparatory move
or a twischenzug. For instance, before a rook
moves to a certain square, it can sometimes harass
the opposing king with a zwischenschach
(i.e. a zwischenzug that is check):
5 .. Jk7 6 l!h6+!
Once again the zwischenschach puts Black
in an awkward situation.

This walks straight into White's central ad-
vance. 7 .. JJ.g7 was more tenacious;

Another strong zwischenschach which forces
the black king to commit himself.

First of all Flohr calmly improves his king,
before embarking on the decisive regrouping
with lb<l3-c5.

Now it is all over. You should always think
very carefully before exchanging a pair of rooks
(see Section E of Chapter 4). However, Black's
position was already very difficult.

The threat of a6 forces Black to fix his queenside
pawns on light squares.
3 ... a6 4 !!bl l!g751'1h21?
A strong waiting move that places Black in a
sort of zugzwang.

Flohr stops any counterplay and targets a6 as
a weakness. The rest is just death throes.
