[Graham Banks]

Hopefully Zevra will now be strong enough to play in my next Amateur Series.

[sovaz1997]

It would be interesting. The level of Zevra is now, of course, not very high (about 2200 per CCRL should be)

Division 9 is just right (http://talkchess.com/forum/viewtopic.php?t=66315)

Nice! How's 1.9 coming along?

[sovaz1997]

The latest test version is about 30 elo stronger then 1.8.1 in 10+0.1. If there is a new version, then 1.8.2. But for the time being I will try to achieve greater growth.

Nice!! Good improvement!

Will need a lot of ELO to stay out of the bottom 16 in Season 3.
