Estrin-Ivashin, 1947
A bishop ending, same colors - 6 pawns each. Black is stuck with the
typical bad French bishop. If his king and bishop move too far away,
the blow Bxg6 followed by f7 will happen. The pawn chain, with its
spearhead at f6, literally cramps black's two pieces. Estrin finds
a nice way to make things clear:
1.b4! axb4 [1.-Bxa4 2.bxa5 followed by Kb2-a3-b4-c5, or 1.-b6 2.bxa5 bxa5
3.Bb5!]
2.Bc2 Bc6 3.Kb2 b6 4.Kb3 Kf8 5.Kxb4 Ke8 6.a5! 1-0
[After 6.-bxa5+ 7.Kxa5 Kd8 8.Kb6 Be8 9.Kc5! Kc7 10.Bd3, black
is in Zugzwang.]
Test: White to move and win. This position might prove hard for chess
programs to win, but you never know... The total game further down.
