Canadian Championship 2023 some observations

[Halldor P. Palsson]

Thanks Hans. After 23.Bxe7 Black goes gf2 24.Kxf2 Qxe7 and if White then takes the knight on h5 it leads to disaster. So 25.Qxh5 and after Qc5 26.Kf1 Bxb5 27.Re2 (or Qe2 or c4) Rxd2 and White calls it a day.

I needed computer help to see the attack break through on c5, b5 and d2. Live I thought Black was over extended because I could not get pieces to the kingside fast enough.

[Hans Jung]

Halldor, I think you mean 22.Nh2. as played in the game. The position is fascinating. After 22..g3 as played White could have played 23.Bxe7 No?

[Halldor P. Palsson]

A game with high stakes. The position after Black plays 21...g4 is hard to evaluate. White is worse if he tries 22.hg4 but after 22.Nh2 no way back is found.

I can't get the live games for round 7. Is it just me?

EDIT: I think game 7 doesn't start till 11.00 am tomorrow, so I'm getting ahead of myself.

[Hans Jung]

The perfect scores in the womens are no more. Valerie Ruchinskaya upset Carina D'souza. Demchenko and D'souza are tied with 5, half a point ahead of Ruchinskaya.

[Hans Jung]

After six Bator Sambuev is the sole leader with 5.5 out of 6, a point ahead of the pack.

[Hans Jung]

Rd 6 Shawn Rodrigue-Lemieux first to finish with a win against Michael Barron.

Exciting attacks in Preotu - Rusonik and Noritsyn - Sambuev.
Bator Sambuev pawn storm kingside attack breaks through!

Cagily played defence and counterattack by Razvan!

[Hans Jung]

Big game Rd 6 Noritsyn vs Sambuev.

[Hans Jung]

After 5 rounds Nikolay Noritsyn and Bator Sambuev are tied for first with 4.5.

[Hans Jung]

Rd 5 womens D'Souza's opponent made it surprisingly easy for her. Demchenko finished with crisp efficiency. It now looks like it will be a chase of the leader Carine D'souza by Svitlana Demchenko. D'souza is a perfect 5 for 5 so far and has also beaten Demchenko in round 4.

[Hans Jung]

Rd 5 there were alot of good endings - no upsets - at least on the top 4 boards.

[Hans Jung]

You are welcome Francis!
