Rather than lost the piece, white decides to give up the exchange.

 
19... Rfe8+
intervening check. The king can't move to f1 because of Bxc4 , and Ne3 loses the rook.

 
20. Be3
Forced, but this pin allows black to eliminate the strong bishop and any play along the long diagonal.

 
20... Bxa1 21. Nxa1 Nxc4 22. Nc2 Nxe3 23. fxe3
To get the king out of the way.
