Hi,
The move 27 Ne1! leads to a forced draw. The interesting aspect is, that
computer programs spot 27 ... Qa7! after a while and then give up the line
because material is lost. Still, looking a bit further gives us the following
possibility:
27 Ne1! Qa7! 28 Qxf6 Qa3 29 Bxg6 hxg6 30 Nd3! Qc3! 31 Rf1! Rxa2 32 Ne5 Qxb4 33
Qf7+ with a draw by perpetual check.
