The game Kulaots,K-Nyback,T, XXI Paul Keres Memorial Rapid 2012, featured a line which hasn't been seen at the GM level for a while. I mean the surprising gambit line 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Na5 10. Bc2 d5!?, which was introduced by the Polish GM Gajewski.
In the diagram position, after the further 11. d4 dxe4 12. Nxe5 c5, White played the rare 13.Bf4, which is, however, the first choice of Houdini. Black answered with the risky, but interesting novelty 13...Bb7, instead of the earlier played 13...cxd4. After the inaccurate 18.Rf1?! (18.Qxd8 was better) Black could have taken the initiative with 18...Qe7.
I have a feeling that White should be able to obtain a slight edge with correct play in the Gajewski system, but as the game showed he has to be very accurate. 13...Bb7 looks like a good novelty, but requires more practical tests.
