And in the 4th round

Lisy beats Burzo

So now Lisy has taken the first professional title, congrats to him!

The remaining four players for the second spot are: Burzo, Surma, Jabarin and Podpera.

Here's the final game

Congratulations to Lisy for winning and also to Burzo for reaching the final!

At move 49, we have the too familiar topic of the left white wall having too little development potential. IMO, the trouble starts with White 8; the stone creates influence on the left side, where Black C6 is waiting. If White wants to approach the upper left corner at this moment, C15 is easier because White can seek life more easily and need not establish a wall.

I have 29 games in my pro database with white 8 and the results were 50/50.

7 games with C15 5/2 in favor of white.

I think that approach was ok, but the joseki choice afterwards of the left side influence was bad due to c6 begins settled. But if we don't answer in the lower left I slightly prefer approaching the top right corner because the left is somewhat flat if black makes the low shimari at top left (and if high some problems too). Also if white can get lower left 3-3 later then black's 2-space extension is low, and if the 4th line knight's move that has the invasion problem later.

Fifth round in Vienna.

Podpera beat Burzo by 3.5
Jabarin beat Surma by resign. Disappointing loss for Mateusz: he was over 20 points ahead going into endgame but tried to play a kikashi before defending a cut but it wasn't sente enough, Ali cut, and a big group became ko for life but Ali had loads of threats from his dead group and elsewhere.

Shame about Mateusz Surma going out as I was rooting for him to be the 2nd pro (met him at Polish Go summer camp, he's a nice guy, modest, studies hard), but Ali Jabarin also impressed me in the CEGO training league (he seemed the only one to be able to hold his own against Zhao Baolong for a decent chunk of the game) so I'd bet on him. I was rather surprised he lost his first game to be honest.

A. Jabarin beat L. Podpera by 1,5 point.

Given Chinese Rules, B+1.5 is the smallest possible winning margin. Who can identify White's game losing move? Surely not as early as move 38.

38 at L7 looks better to me.
