Kibitzer's Corner
Mar-19-13  vinidivici: You can read about this game in SCE1 since the author was the trainer of Nana at that time.

Noted that 41...Rf8 is a sealed move and of course its an obvious move. When they came back on board after the rest day and the envelope uncovered and the arbiter made the sealed move, Litinskaya got surprised how white responded it with 42.Kg1. But thats just a strategy of home analysis with enclosing the element of surprised. Litinskaya thought a long time there and the hard work paid off for white because the result is draw.

Noted that beside 42.Kg1, there are 2 other choices remains...42.Ke1/Rd2.

42.Rd2 line is the weakest since the white rook now at the 2nd rank and we see the ending implicating the opposite-colored bishops and they cannot kill each other so the activity of the rooks are important. Since the white rook in the 2nd rank, it cannot move to the b-file because guarded by black bishop, thats why it is the weakest.

I learnt hours for the position and for me 42.Ke1 is the strongest (contrary with the Nana and the author thought). Since after 42.Ke1, 42...Rxf2 is impossible due to 43.Rxd4+.

Anyway, 42.Ke1/Kg1 are better than 42.Rd2.
Whats the first comes to mind between Ke1 and Kg1 is that the centralization of the king, one submissive to the principle and one disregard it. But the both lines deserves to study. And only an admiration i can present for the white side, since they chose the "little weird" move Kg1 and puzzling her opponent. Perhaps sometimes in the future i will post the calculations i made and its quite complex.

Mar-20-13  vinidivici: And one again:
the Kg1 move can be aligned with this theories:
"If there are no other pieces on the board apart from the opposite-colored bishops and the kings, the weaker side should normally defend PASSIVELY, aiming to set up a fortress"

"On the contrary, when other pieces are present, the main principle is ACTIVITY, a striving for the initiative, EVEN AT THE COST OF MATERIAL. After all, the presence on the board of opposite colored-bishops usually strengthens an attack, since active bishop has no opponent."
