What could this 100% classical opening have in common with Lasker's bishops? I gently ask for your patience, the similarities will come out later. And you should not be misguided by the big rating difference to White's favour. Iotov had played a fantastic tournament so far, with 6,5 out of 7, including wins over Karjakin and Tiviakov!} 2. c4 c6 3. Nf3 Nf6 4. e3 a6 5. Nbd2 Bf5 6. Nh4 Be4 7. Be2 {A rare move, developing the bishop on an apparently modest square.} ({The usual continuation is} 7. f3 {but, anticipating a bit, White will need the d1-h5 diagonal for inserting the queen into the attack.}) 7... e6 8. O-O Bd6 9. g3 Nbd7 10. Nxe4 Nxe4 {[#]White has gained the bishops' pair without making any major concession. The awkward knight's position on h4 is temporary as White could retreat with it in any moment. Moreover in the game Eljanov will find a way to send it to the first lines of his attack! But any attack must be prepared and over the next three moves White will finally display his bishops according to the Lasker pattern.} 11. Bd3 Nef6 12. b3 O-O 13. Bb2 {The position is typical for the Slav Defence. White has the bishops' pir and more space, but Black's position is solid and flexible at the same time. But flexibility means a wide choice of plans, which psychologically may be difficult to handle. For practical reasons it is simpler when there is only one reasonable plan available. In such cases, one sticks to it and does not have to spend time and energy on making choices. In any case, Black's choice on the next (13th) move, consuming roughly 13 minutes, was a rather unfortunate choice.} c5 $6 {This pawn break will lead to the radical activation of the white bishops. White was not threatening anything yet, so Black could and should have simply improved his position.} ({My favourite is} 13... Qe7 {planning either ...g7-g6 followed by ...e5, which would more or less neutralize the b2-bishop, or just the bishop exchange with . ..Ba3 (Bc3, . ..Bb4).}) 14. cxd5 Nxd5 15. dxc5 {The bishops' diagonals are wide open and the position finally acquires some similarities with Lasker-Bauer.} Nxc5 $6 {This apparently active move, gaining one tempo by atacking the bishop, takes the knight too far from the kingside.} (15...

Rfd1 {White's position is more active and his bishops' pair may have the telling in the endgame, but Black has chances for (true, joylessly) defending.}) 16. Bc2 {[#]Sudenly, there are many white pieces targeting the black king: the bishops, the queen, and, as surprising as this may sound, the knight.} Be7 {Black tries organising a general retreat for defensive purposes, but he is one tempo too slow.} ({The other possible way to initiate this plan,} 16... Nf6 $2 {would lose for several reasons, the simplest being} 17. Bxf6 gxf6 18. b4 {winning a piece.}) 17. Qh5 {The previous inacuraccies have put Black in a dangerous situation. He has to choose now between three pawn moves for parrying the mate on h7. This is a critical decision which required some deep analysis. Instead, Iotov answered after only 6 minutes.} f5 $2 {This weakens the position too much.} ({ Actually, Black's choice lied among two moves only, since} 17... g6 $2 {would lose on the spot to the obvious} 18. Nxg6 fxg6 19. Bxg6 {Even though not as spectacular as Lasker's combination, this simple line illustrates the force of the bishops perfectly well.}) ({The only way to stay alive was} 17... h6 $5 { White would need acting quickly, otherwise ...Bf6 would suddenly offer Black a great game. The c3-square would turn weak and the c2-bishop would be left without scope. I cannot know the reason why Iotov rejected this move, but the only way to keep the initiative on would have been based on a sacrificial knight jump to f5. Unlike in the game, this would have happened without pawn capture.} 18. Nf5 $5 ({Alternatively, White could centralise a rook:} 18.

Nb5 b6 {[#]Once again, the relevance of this game with our main classical theme is unclear. Is there any danger for the black king? Do not worry, there will be! So far, both sides had played relatively quickly, but Cheparinov spent 12 minutes on his next move.} 16. Nd6 ({A novelty over} 16.

The bishop was not doing much on the long diagonal, while from a3 it creates all sorts of tactical motifs. The immediate threat is 18.Nb5 Rcc8 19.Bxc6 winning a piece.} Kf8 {Since White's coordination is obviously better, Ponomariov tries to relieve his position by using numeric superiority. This is a known method when the game gets close to an ending. If the defending part can use his king as an extra piece in the main area of combat, he has all the chances for a favourable outcome. The main problem is that the position is far from getting to an endgame yet, being closer to a complex queenless middlegame.

Nb5 Rcc8 20. Bxc6 Rxc6 21. Nxa7 Rc7 22. cxb6 {In this line, the Catalan bishop proved its force by a well-timed capture on c6. With his last move, Ponomariov not only cleared the long diagonal, but took the b5-square under control as well. In doing so, he failed to notice the hidden force of the other bishop. This way we can conclude that the bishop's team work had a more subtle character than in the previous and in the Lasker's game.}) ({A better way of neutralising the g2-bishop would have been} 18... Nd5 {In some lines White may win a pawn, but his pieces could be left a bit hanging.}) 19. Nb5 $1 { Unexpectedly, this move is possible and winning! Ponomariov sank into deep thought (possibly interrupted by self-reproaches) for almost half an hour, but there is nothing to be saved anymore.} Rcc8 ({The tactical point is that} 19...
