Prague Summer Open - Adam Bremner - 07-08-2015
Good luck to Hamish Olson and Neil Irving playing in the A section starting today. Hamish is on a live board, black against the top seed, a 2575 Russian GM. <!-- m --><a class="postlink" href="http://www.czechtour.net/summer-prague-open/online/">http://www.czechtour.net/summer-prague-open/online/</a><!-- m -->
Re: Prague Summer Open - Alan Tate - 07-08-2015
Interesting. I'm torn between this and the other threads of endless debating of technical details, point scoring and pedantry.
On a brighter note, Vorobiov is a real grinder. A kind of archetypal Russian who plays without emotion and nerves. It will be a good experience for Hamish.
Re: Prague Summer Open - Adam Bremner - 07-08-2015
Yeah, it feels odd to be trying to discuss actual chess.
Seems you were right enough about this GM's style, but I'm going to back Hamish to draw here. He is good at these sorts of positions.
Re: Prague Summer Open - Alan Tate - 07-08-2015
I didn't mean that he can't get a result, but that it may be a long and difficult game. These positions are always a little better for White but I seem to recall that it's very hard to make progress with so few pieces left. Surprised that Vorobiov exchanged knights but what do I know.
Re: Prague Summer Open - andyburnett - 07-08-2015
These endgames are very difficult to defend. I would expect white to grind out a win from here (move 26) although I hope Hamish holds on
Re: Prague Summer Open - Adam Bremner - 07-08-2015
These positions do tend to be a GM's dream to play for white, although I would have loved something like this with black in half of my games last week! Looks like they are both about to hit time trouble, and I reckon the result should become clear at move 40.
Re: Prague Summer Open - Alan Tate - 09-08-2015
It's seemingly tough to get on those live boards.
Re: Prague Summer Open - andyburnett - 09-08-2015
Yep
Until such time as Hamish drags himself back into the online action, I've taken to supporting and following my pal Nondas (Epaminondas Kouroussis - A Greek/Czech IM who is also a dentist in Prague) and also the young Ukrainian with the very bad haircut (Kirill Shevchenko) who I played last year in Brno (see the game below) and who had an easy draw today with the top seed who beat Hamish in round 1.[pgn][Event "Brno open"]

Taking stock, white has the bishop pair and a q-side pawn majority. On the
down-side, his king will be awkwardly placed when he tries to do anything with
them, and for the moment black's pieces are all fairly active. So, white
should be better, but perhaps not by much or easy to prove. I felt my first
priority ought to be preventing Ra5, when the a-pawn feels a bit uncomfortable.

Re: Prague Summer Open - David G Congalton - 09-08-2015
Looks like Hamish has dragged himself back onto the live action tomorrow with a good result against his 2201 rated Czech opponent today.
Neil Irving's having a good event so far, as well, sitting just off the leaders in the B tournament.
