Naum 3 - Toga CMLX '1.5' beta 1

[Eelco de Groot]

Maybe this is a bit better place for the match to continue than the Rybka forum, after all it does not have very much to do with Rybka. In the second minimatch played at a longer timecontrol Naum won convingingly in the first game but the second game Naum's superiority was not so clear, and Toga CMLX played a beautiful Bishop sac on h6 to crown a good game.

It is hard to be sure but I think that Toga with its new timemanagement took a bit longer for its moves after leaving book, which was my intention. There were some last minute move changes, if the timemangement helped there it may have contributed a bit to Toga's success in the second game!

[Eelco de Groot]

The next round were two Nimzo-Indian games again, the first was a very long game that I did not watch closely and maybe not so interesting to reproduce here. A test for the time-management function of beta 1, with 139 moves in game three. Both games ended in a draw so the result still even.

In game five Naum won convincingly again and I thought Naum would now take the lead because the return game seemed roughly in balance for a long time, even a small plus for Naum with the Black pieces. But in the endgame Toga, maybe with a little luck, managed to equalize, then get to plus one in eval, and then, I had not thought it possible, a few moves later it got a winning advantage!

Game five:
