I looked but I don't see it...

Qxe3 fxe3 Kf6 Kf1 Ke5 Ke2 and how does white win?  Opposition doesn't work as
black has a pawn move to make where white does not.  Crafty says dead draw with
6 piece endgame tables:

               20->  20.30   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>
               21    23.40   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>
               21->  41.46   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>
               22    44.99   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>
               22->   1:04   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>
               23     1:10   0.01   3. Kf1 Ke5 4. Ke2 f5 5. Kxe3 Kd5 6.
                                    Kd3 Kxc5 7. g4 fxg4 <EGTB>

I agree that the distant white pawn looks problematic, but the black e pawn is
also a problem that burns tempi to stop...  What do you suggest after we play
this out to the above?  Or would you vary somewhere along the line.  I can rin
most anything at the moment...
