   Dec-04-22 Tarrasch vs K Walbrodt, 1895
tbontb: This brilliancy prize game is dynamically equal for a long time until Black Waldbrodt misses his chance of 33....Rf8 34.Rxd4 cxd4 35.Bxd4 Qxf5 35.Rxf5 Rgxf5 to leave White Tarrasch struggling. Instead, 33....Nh5 as played loses immediately to a pretty attack on the d4-h8 diagonal.
   Dec-03-22 Steinitz vs B Vergani, 1895
tbontb: A thematic game. White Steinitz's K-side attack proves much more virulent than Black Vergani's Q-side play.
   Nov-28-22 Lasker vs G Marco, 1895
tbontb: After a tame (provocative?) opening by Lasker White, 15....d4 16.exd4 a6 17.Nc3 Nxd4 would actually be better for Marco Black. Instead, 15....Qd7 resulted in dynamic equality until the blunder 22....Bf6 lost immediately (when simply 22....Bd6 23.exd4 Bc7 24.Bg4 f5 still maintained ...
   Nov-27-22 Chigorin vs Pillsbury, 1895
tbontb: Black Pillsbury stumbles into an opening trap but White Chigorin plays inaccurately with 14.Qxf7 (better 14.Bg5). Later 23....Bg5+ is an improvement on Bb4+ but at the end 32....Qb3+ allows White a relatively easy win (better 32....Qa1+ with equality).
   Nov-26-22 Pillsbury vs Tarrasch, 1895
tbontb: A see-saw struggle where after 40....gxf6 (better Nxf6) Black Tarrasch lost a fine game he might have won even earlier (eg. 38.....fxg5 39.Qg5 Nf6 looks clearly good for Black). 31.Nc1 was perhaps too optimistic but White Pillsbury risked all and deservedly won on the day.
   Nov-20-22 Barcza vs Bogoljubov, 1942 (replies)
tbontb: The ending proves advantageous for Barcza White as Bogoljubov's Black 19....b4 is tempting but ultimately weakening (simply Bxc3 maintains equality). However, Alekhine's later suggestion 31....a6 also fails to equalise after 32 Rb6 Ra3 33 Nc4 Rxa5 34 Rh6, so 31....Kd6 seems the best ...
   Nov-19-22 Stahlberg vs M Castillo, 1939
tbontb: Black Costillo allows his Q to become dangerously short of squares so must accept a shattering of his Q-side pawn structure. After 25. Rxe7 White Stahlberg is clearly better, so the last chance is probably 24....Rd7 25 Rxd7 Bxd7 26 Rc7 Rb1+ 27 Kh2 Bb5, still with advantage to White.
   Nov-12-22 Ding Liren vs Nakamura, 2022
tbontb: A historically important game which is mostly equal until Black Nakamura's 35....Bd8 (better Rd8), with White Ding pressing hard for more and eventually achieving an advantage after 40. Kg2. In retrospect, 41....f3+ in search of counterplay seems too committal. Finally, Be3 traps the
   Nov-12-22 Caruana vs Firouzja, 2022
tbontb: A difficult game to analyse. The position was dynamically equal for a long time until the unconventional b5 resolved into an ending where Black Firouzja always had the advantage with B against N. Caruana White defended doggedly but finally 60. Ne4 (better Nf3) was a definite error ...
   Nov-11-22 Caruana vs Ding Liren, 2022
tbontb: A game coloured by the tense tournament situation with both players "needing" to win to stay in contention. Caruana White was better for much of the time until 50. Be5 allowed Ding Black to fight back to equality with 55. ....Kg7. After 57. Be3 (better Qd5) the advantage passed to ...
