[Event "Koelle 'A' 2018"] [Site "Mechanics Institute"] [Date "2018-10-17"] [White "Rodney Jacobs"] [Black "Tom Oppenheim"] [WhiteElo "1692"] [BlackElo "1114"] [Result "1-0"] 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 {In his book My 60 Memorable Games Fischer referred to the fact that Tarrasch had called this a 'duffer's move'. It does break the maxim of not losing a tempo by moving the same piece twice in an opening. But Fischer felt there is no other way for White to try for an advantage. (RJ)} d5 5.exd5 Nxd5 {Departing from the usual two knights defence move of Na5 and inviting the fried liver attack, with which Tom was familiar.(RJ)} 6.Nxf7 {The Fried Liver Attack - fantastic name for an opening! Also known a the 'Fegatello Attack' - apparently meaning 'dead as a piece of meat. (RJ)} Kxf7 7.Qf3+ Ke6 8.Nc3 Ne7 {Nb4 is slightly more popular. (RJ)} 9.d4 {O-O is the book move. But both my programs pick d4. Fascinatingly, Stockfish 7 says White already has a decisive advantage of 3.25, but (the weaker) Deep Shredder says it's even. (RJ)} c6 10.Bg5 {From here it's a fascinating challenge for both players, with all the issues typical of gambit play, but exaggerated. White has given up a piece in return for an exposed Black king and a large lead in development. He must keep his dynamic advantage and make something of it fairly quickly, or lose. Black must survive the onslaught, seek to exchange pieces, deaden the position and get his king to safety. Both my engines say Bg5 this dissipates much of White's advantage, saying de should be played. It's odd that White's best move is, apparently, not a developing move. (RJ)} h6 $10 {Selected as best by both my programs. (RJ) bishop take e7 fritz16} 11.Bh4 g5 $15 {Again best. (RJ) black is slightly better fritz16 jb} 12.Bg3 Bg7 {Also the best move. (RJ)} 13.O-O-O {Stockfish 9 likes h4 a little better. Both my programs now put it at -.7. (RJ)} Rf8 $15 {Tom is playing very accurately. (RJ). I had, wrongly, thought Qf8, with a view to Qf5, was better. (RJ)} 14.Qe4 {The engines like Qh5 a little better. (RJ)} Qd6 $18 {Kf7, scurrying for safety, is the move. (RJ).} 15.Rhe1 $10 {Returning the favour. I too was finding it very hard to calculate in this position. de! is the move. (RJ). Black has now a slight edge again. (RJ) fritz16 syaing it,s equal jb} Rf5 $16 {An indication of the complexity of the position is that Deep Shredder - rated at 'only' about 2700 feels this is not bad, but Stockfish 9 (3456!) says it's a bad error. Both prefer again Kf7. (RJ)} 16.Qg4 $15 {Again apparently de is best. (RJ)} Ng6 $19 {Once again Kf7 is the move. White now has a significant advantage. (RJ) black is winning fritz16 jb} 17.dxe5 {Finally making the correct move. (RJ)} Bxe5 18.Bd3 {Not bad, but the engines prefer 18. Bxd5 cd 19. Rxd5. (RJ)} Kf6?? {Overlooking the pin. Qf8 is called for. But White still would have a sizable advantage.(RJ)} 19.Ne4+ Kg7 20.Nxd6 Rf4 21.Ne8+ Kf7 22.Qh5 Bf5 23.Rxe5 {#r}
