White plays Na4 and pawn c5 falls.
It is black to move.
Does it involve giving up material?
I don't think there is one answer though. It is more of a positional problem.
Rook d4, i think, one rook for bishop pair, not a big price for dynamism.
Sorry, english isn't my mother tongue.
Well known position :-)
Victor Liublinsky vs Mikhail Botvinnik
Russia (1943), Tournament, Moscow
I didn't know this game but it's matter of logic with this position(it's my opinion with my little knowledge), bishops need diagonals and rooks rank, cancelled ranks and open diagonals, and well done. Thanks for game and names of gamers, and go on with positions for finding solutions.
