Kibitzer's Corner
Jul-14-08  emayev: after 35 Re6, white wins because g6 is double teamed. Bishops move in diagonals but rooks move in straight lines.
Jul-15-08  arsen387: I like the combination starting with 26.f4! If 26..Nxf4 then 27.Qg3 pin is very troublesome for Black. And in the end there's no defense against simple Re6 and Bxg6. Nice game by Jako
Jul-15-08  LKor: 32. ...Re7 seems to prolong the fight.
Also, 33. ...Rd6 avoids for the moment white's Re6 (34. Rce1 Nc8), but still looses to the simple 34. Na2 threatening Nf7 (if 34. ...Rf6, then 35. Rf1).
Jul-15-08  visayanbraindoctor: Jakovenko - Bologan probably had Bologan missing 26. f4! maybe for psychological reasons. In the previous position where he played 23... Qf6, the key f4 square (around which the battle revolved in its crucial atages) was defended by both his e5 pawn and g6 knight and indirectly by his f6 queen, and he probably thought it was secure. Jakovenko nevertheless was able to play 26. f4 anyway because of tactical reasons involving the pin on the b1-h7 diagonal and the subsequent hanging black queen on f4. Must have shocked Bologan. 31. h4 helped fixed the pinned g6 pawn. By this time, Jakovenko probably had hit on the plan of occupying g6 with the white bishop supported by a rook on e6. A g6 Bishop then controls the e8 square for the advancing passed pawn. But black resigned before we could actually see this plan carried out on the board. A very nice mix of good planning and tactics by Jakovenko resulting in a quick knockout.
Jul-17-08  ozmikey: Maybe I'm missing something obvious, but I can't see a clear win after 26...Nxf4. If 27. Qg3 then simply 27...Ng6 seems to hold, and 27. Rc5 Qc7 28. Qg3 is very strong but not immediately decisive. Is there anything better?
Jul-17-08  myschkin: <my silicon pet> says ....

26...Nxf4 (is ok, but played like the last given line)

27.Qg3? Ng6? (e.g. 28.Qf2 Kh8 29.Rc5 Qf4 30.Qxf4 Nxf4 31.e5 Rd2 32.Be4 Rxb2 ...) <even>

27.Qg3? (e.g. 27...Rd2 28.Rc2 Rad8 29.Qe3 Rd1 30.Rc1 Rxe1+ 31.Rxe1 c5 32.Rf1 Ne6 33.Ne7+ Kh8 34.Qf2 ) in black's favour (-1.11)

27.Rc5 Qc7 (e.g. 28.e5 Qb6 29.Nd6 Ne6 30.Rcc1 Ra6 31.Ba2 b4 32.Bc4 bxa3 33.bxa3 Qxe3+ 34.Rxe3 Ra7) <even>

From IM Max Notkin's excellent annotations in Chess Today #2813:

<With a cunning idea of the double exchange on e5 followed by Rc5.>

So 19 ♕d2-e3 Δ 20 d4xe5 ♘d7xe5 21 ♘f3x♘e5 ♕e7x♘e5 22 ♖c1-c5, <SKEWERING> the Black e5-queen against the <UNDEFENDED> Black h5-knight.

Like Reinfeld/Chernev used to say in regards to the <UNDEFENDED> Black h5-knight in the original diagram, <<<THERE ARE -ALWAYS- THREATS AGAINST UNDEFENDED PIECES>>>.
