INDIAN DEFENCE
The Yusupov-Rubinstein System
Black advanced a pawn to QB4(c5) attacking White's QP and hoping for 4.PxP..BxP development.
White declines 4.PxP and develops King's Bishop to Q3(d3). Play tends to continue 4...P-QKt3 for a QB fianchetto and easy equality, or can transpose by 4..P-Q4, 5.QKt-K2..QKt-Q2 to the Colle. W-Alt.
	White	Black
 1.	P-Q4	Kt-KB3
 2.	Kt-KB3	P-K3
 3.	P-K3	P-QB4
 4.	B-Q3
