Sep-30-25 R Potze vs N Beijerinck, 2009 
| |
| TheaN: Bleh. Saw <24....Rxc1 25.Rxc1 Qf4+ 26.Qg3> but assumed after <26....Qxc1?<>> 27.Qb8+ Kg7 28.Qxb7 Qf4 (Be5+ even better) -+ and Black should win easily, but missed <27.Qxg6+! =<>> completely. Bit involved for a Tuesday, spotting Rxc1 first and then not ... |

Sep-29-25 V Kozlovskaya vs R Sucha, 1973
| |
| TheaN: #3 with <28.Rxf7+>, 28....Kg8 29.Qxg6 Kh8 30.Rh7#, 28....Kh8 29.Qh6+ Kg8 30.Rg7#, and <28....Rxf7 28.Qxg6+ Kh8 (Kf8 29.Qxf7#) 29.Nxf7#>. Recognizable patterns with QR and QN, especially with the weaknesses of the squares a knight jump from the corner (in this case f7 and ... |

Sep-24-25 M Erwich vs R Potze, 2003
| |
| TheaN: I was pretty sure it had to be <37.c5> by deduction (both colours are a bit stuck here). After <37....Rxd5> <vajeer> is right, White can either play the text, which I looked at but missed 39.c4!, or <38.Be6?! +-> where White gets rid of a2 and has a won ... |

Sep-22-25 N Miezis vs A Danin, 2009
| |
| TheaN: Bit sloppy as I thought White couldn't prevent promotion altogether, but alas after <38....Qxc1+ 39.Qxc1 Rd1+ 40.Qxd1 Bxd1 -+> White will have to give his last piece to stop the a-pawn <at least> and Black will win fairly easily (king's close enough to the e-pawn to ... |

Sep-15-25 Landa vs A Ivanov, 1985
| |
| TheaN: Holy *%# I completely missed the h-file is open. I've been looking at the position for 5-10 minutes. Probably one of the worst blindness I've had in recent months. I played <22....d5?!> with the idea <23.Bxd5 (Nxd5 Bxe2+ -+) Rxd5 -+>, for as far as I can see this wins even |

Sep-09-25 Vasiukov vs Alburt, 1972
| |
| TheaN: Wow, both Monday and Tuesday on point this week. <17.Qxe8+!> clears f7 and picking up Re8 <17....Rxe8> for what it's worth, after either interposing 18.Nf7+ +- anyway <18.Nf7+ Kg8 19.Nxd6 +-> and because Nd5 is hanging White wins a full rook, not the exchange, and ... |

Sep-09-25 Abdusattorov vs Y K Erdogmus, 2025
| |
| TheaN: On move 113 everyone was rightfully claiming "Nd4 is a draw". Some were saying it's an <easy> draw. It really isn't, Black is walking a 75-move long tight rope and misplacing queen or king once leads to a very simple loss, as White can trade and wins. Incredibly impressive. |

Sep-08-25 Seirawan vs Van der Wiel, 1978
| |
| TheaN: "I'll do it myself" moment here, given after <28....Qxh2+ 29.Kxh2 Kg7/Kg8+> it's essentially the Black monarch pulling the trigger (which is the h8-rook). Sadly it's not mate straight away, rook has to fire again himself, <30.Bh3 Rxh3#>. |

Sep-02-25 M Sion Castro vs J Cardenas Valero, 1998
| |
| TheaN: I actually managed to go the long route with this one... but lets add one more move to the winning moves for Black: <28....Qe2+!? 29.Qf3 (Kxg5 Qh5#) Rh4+!>:
[DIAGRAM]
Black just starts a long sequence of remove-the-guards of the White queen and in all variations the rook falls |

Sep-01-25 Kaidanov vs Anand, 1987
| |
| TheaN: Very rare pattern here <25.Qxf7+ Rxf7 26.Ng6+ Kg8 27.Rh8#> where all White pieces work beautifully to ensnare the Black king. It's striking that even someone like Anand can judge such a position wrongly. On move 23 he's up after 23....Kf8 ∓. 23....Bd5?! is a slight ... |
