It is not a clear cut position. I post Kasparov's analysis about 26... Re3,
hoping I don't infringe any copyrights.

26... Re3 $1 {All of a sudden the white king feels insecure. The audacious
rook cannot be taken: Auf einmal ist es der weisse Koenig, der sich nun
unsicher fuehlt.} 27. Nf3 $2 {From now on Alekhine makes a series of moves
that sweep Whit off the board. Von nun an fuehrt Aljechin eine Reihe von
Zuegen aus, die Weiss foermlich vom Brett fegen.} ({
Der freche Turm kann nicht geschlagen werden:} 27. fxe3 $4 Qxg3+ {
with mate; and even after nebst Matt;}) ({und auch nach} 27. Bg2 Rxg3 $1 28.
fxg3 $2 ({Hier ist} 28. e3 $1 {is much stronger, but Black still has
sufficient compensation for the sacrificed material: viel staerker, aber
Schwarz hat immer noch genuegend Kompensation fuer das geopferte Material.:}
28... Nxe3 29. fxe3 Nd5) 28... Ne3 29. Qd3 Qxg3 {wins. In the last variation
28.e3! was much stronger... (see above). Alas Alekhine's original attempt to
complicate the position could have been met by simply gewinnt Schwarz.}) ({
Leider konnte Aljechins origineller Versuch, die Stellung zu verkomplizieren,
ganz einfachdurch} 27. Bf3 Bxf3 28. exf3 {ending Black's activity; or even by
the cold-blooded abgewehrt werden, wonach die schwarze Aktivitaet zum
erliegen kommt.}) ({Auch das kaltbluetige} 27. Kh2 {Black will continue to
apply pressure on g3: war spielbar. Schwarz wird weiterhin Druck auf g3
ueben:} 27... Raa3 $1 {
and the rook still cannot be touched der Turm ist immer noch tabu} 28. fxe3
Nxe3 29. Qb4 Nf1+ $1 30. Kg1 Qxg3+ 31. Bg2 (31. Kxf1 Bh3+) 31... Ne3 {
and mate. But the quiet 28.Ncb3 would have given White the upper hand.
