Peter SVIDLER - Ruslan PONOMARIOV 
European Club Cup 2012, Round 5

English Opening
1.c4 Nf6 2.Nc3 e5 3.Nf3 Nc6 4.g3 Bb4 5.Bg2 0-0 6.0-0 Bxc3 7.bxc3 Re8

Svidler: "I always wondered why 8.Ne1 wasn't played any more. Well, it's clear that was because of 8...d5but it seemed to me that you can get an interestingly unusual position here, so today I have eventually decided to check what people think about that. 

9.cxd5 Nxd5 10.Qc2 Bg4
Ruslan chose a very natural reaction: he forces 11.f3, then he plays 11...Be6 12.e4 Nb6 13.d3 Qd7

14.f4 f5. Now if White find anything, Black may stand just a bit better. However, there's an important move 15.g4 after which a strange position appears. Maybe he could beat this pawn, of course not everyone would do so - 15...fxg4 16.f5 Bf7... and it's also clear that strategically I have a huge compensation in that position. 

Ruslan chose: 15...fxe4 16.f5 Bf7 17.Bxe4 Nd5 18.g5 g6 Here we got a strange position again, I wanted to keep it tense but perhaps I made a very inaccurate move 19.Ng2. I was thinking it would be advantageous for me to force him to play 19...Nce7 and to play 20.f6 with some tempo, only after that; however, he moved his knight to a brilliant square -  20...Nf5. So it's most likely that I had to play 19.f6 immediately in order to keep the knight on c6, where it would be isolated.

The position stays unclear. I made a terrible move 21.Rb1 - lost tempo and after 21...c5 it's unclear who stands better. 

Then we both had time trouble in an intensively complex position where you had millions of opportunities after each move. I was lucky: I played a bit more accurately. 22.Rf2 Nd6 23.Bf3 c4 24.dxc4 Nxc4 25.Qd3 e4 26.Bxe4 Ne5 27.Qg3 Rac8 28.Bd2 Qg4 29.Qxg4 Nxg4 30.Re2 Nxc3 31.Bxc3 Rxc3 32.Rxb7

Even here the position still could be quite unclear if he hasn't played 32...h6. Let's say he plays 32...Rc1+ 33.Ne1 and 33...Kf8 threatening  Bc4. It's hard to imagine that I don't stand better, but the position is very concrete, I should solve concrete problems.

And after 32...h6 33.h3 I just didn't see how to defend. 33...Rxh3 34.Bd5 Rxe2 35.Bxf7+ Kf8 36.Bxg6 Re8 37.Rf7+ Kg8 38.Rg7+

It's a pity he played  38...Kh8, instead of 38...Kf8, because in that case I would play 39.Rg8+ Kxg8 and you have an excelsior: 40.f7+ and 41.fxe8. It's not that usual to be able to demonstrate excelsior on a board..."

39.Rh7+ 1-0

In another decisive game of this match Nikita Vitiugov took an upper hand on Viorel Bologan.

P.S. Sam Loyd's excelsior

The chess problem is named after the poem "Excelsior" by Henry Wadsworth Longfello. According to the legend one of the Loyd's mates always had a friend who was willing to wager that he could always find the piece which delivered the principal mate of a chess problem. Loyd composed this problem as a joke and bet his friend dinner that he could not pick a piece that didn't give mate in the main line (his friend immediately identified the pawn on b2 as being the least likely to deliver mate), and when the problem was published it was with the stipulation that white mates with "the least likely piece or pawn."

Solution:
1.b4! Threatening 2.Rf5 any 3.Rf1# or 2.Rd5 any 3.Rd1# (with possible prolonging of both by 2...Rc5 3.bxc5 any 4.R mates). White cannot begin with 1. Rf5 because Black's 1.... Rc5 would pin the rook.
Now there are multiple possible half-defences defending only one of threats and one secondary non-thematical defence:1...Rxc2 2.Nxc2! a2 3.Rd5 (or Rf5) a1Q 4.Nxa1 any 5.R mates.
1…Лc5+ 2.bc!  Threatening 3.Rb1#.
2…a2 3.c6! Again with the same threats as on move one, i.e. 4.Rf5 any 5.Rf1# or 4.Rd5 any 5.Rd1#.
3…Сc7 Because both Rd5 and Rf5 are threatened; the alternative moves 3.... Bf6 and 3.... Bg5 would only defend against one or the other, i.e. they would half-defend. The given move does defend against Rd5 in the sense that 4.Rd5 Bxg3 5.Rd1+ Be1 6. Rdxe1# takes more than the required five moves, and similarly for 4.Rf5 Bf4.

4.cb any 5.bxa8=Q/B#The mate is delivered with the pawn which starts on b2.
