Jul-09-25 E Vegh vs J Polgar, 1989    Andrew Chapman: I had Ne4 forgetting that black can defend with Nd5. Turns out it's quite good (+3) because the knight can go on to take on Nc5. Nh7 is less than +1 because of Nd5.      Jul-01-25 Abdusattorov vs P Maghsoodloo, 2025   Andrew Chapman: 27..d6 seems to have been the decisive mistake.      Jun-19-25 J B Bjerre vs X Xu, 2025   Andrew Chapman: Evaluation doesn't change after 30.Rd7 but I can understand that rook against bishop and three pawns seems more definitely lost than being a pawn down.      Jun-12-25 I Smirnov vs V Vetoshko, 2007    Andrew Chapman: <In the game line, the king is still tempted by refusing the B, following with: <25...Kxf6 26. e5+ Kf7> 27. Qg5 dxe5 28. Bxh7 exd4 29. Bg6+ Kg8 30. Bf5+ Bg7 31. Rg1 Rc7 32. Qg6.> 29.Bg8, elegant.      Jun-11-25 R Praggnanandhaa vs Gledura, 2025   Andrew Chapman: Apparently, 37. Qf4 was a mistake, bringing the evaluation down from +3 to 0. Then black needed to play 38..Qb8 rather than Qb7. But I don't know why I am afraid..      Jun-10-25 R Praggnanandhaa vs R Hovhannisyan, 2025   Andrew Chapman: 27..Nc5 is hard to understand, allowing the pin. Computer doesn't like it at all - evaluation goes from +0.6 to +2.4. Nf8 was best apparently.      Jun-10-25 N Riumin vs Alfeevsky, 1928    Andrew Chapman: I thought Rc1 was odd. I was expecting Re1.      Jun-02-25 D Gukesh vs Carlsen, 2025    Andrew Chapman: I wonder how long it would take the GM commentators to realise that Ne2+ was losing if they didn't have an evaluation bar in front of them?      May-29-25 Caruana vs A Erigaisi, 2025    Andrew Chapman: Another game where the move which looked weird and bad to a patzer like me, turns out to actually be bad (at least according to the computer), even losing: ie 28..dxc4, giving up the exchange. The natural Rg8 is apparently best. Evaluation goes from +1.1 to +2.8 after dxc4. ...      May-28-25 D Gukesh vs Nakamura, 2025    Andrew Chapman: Computer says that the odd 31..Qd6, which no patzer would play, was in fact really bad. Instead it recommends getting the knight to b6 via a4.
