Analyzing the game suggest that using more time after the score drops
significantly relative to previous iteration could help movei to avoid g5 and
find Rf7 that was probably better and I need to improve my time management(I am
not talking about using more time after fail low because the fail low is in the
next iteration but movei stops at the end of the iteration).
I guess that probability for fail low after fail low is bigger and it is a
reason to use more time after fail low to verify that there is not another fail
low in the next iteration.
After 33...Rf7 34.Re8+ Kh7 35.Rxc8 Ra5 it seems that black is clearly winning.
Unfortunately movei did not like it because it was afraid from
36.Rc7 Rxc7 37.Qxc7 Rxh5 38.Qxb7 Rxh3 Qxc6 with only 2.96 for black.
Deeper search gives better alternatives for black than Rxh3
