27.Kxg2??
can you explain this tactical blunder?
This is the relevant position:
6k1/q3rpb1/1p3npp/p1n1P3/2P3P1/1PN4P/P1Q1RPb1/3R2K1 w - - 0 1
After 27.exf6 white has a big advantage for example:
27...Rxe2 28.Qxe2 Bxf6 29.Qe8+ Kg7 30.Kxg2 Bxc3? 31.Rd8 Kf6 32.Qh8+ Ke7 33.Re8+
Kd7 34.Qf8
The best move for black is probably 27...Bxf6(instead of Rxe2) but after it
white has 2.xx pawns advantage
1679 seconds were not enough for hiarcs7.32 to find 27.exf6
I guess it is 1679+568 seconds because Hiarcs7.32 could use the permanent brain
and it probably expected Bxg2.
Can hiarcs7.32 find 27.exf6 if it has enough time?
