According to Yace the position was equal even after 22.Rf1

shredder's blunder that gave tal 0.5 pawn advantage was 22...Rd7
Yace recommends 22...f6

I do not know if the sacrifice 15.Bxh6 is correct

If it is possible to beat with it every program and not only shredder it is
going to be a stronger evidence.
