This is the best line I could come up with, but I'm sure somebody could improve for either side: 28.Ng4 Nxg4 29.hxg4 Rxe3 30.Kh2 bxa3 31.d7 Rd8 32.Rxe3 Bxe3 33.Qxe3 Qxd1 34.Qe8+ Kh7 35.Qxd8 a2 Also notice that it took Offset over 18 minutes to see a just a very small difference between Ng4 and d7. jm
