HERE is a position from my round-six game at the Cap Negret 65+ seniors.
 |
| Black has just played 18...Ra8-c8, the idea obviously being to seek counterplay down the c file before White's kingside attack hits home |

The game continued 19.Bb1! g6 20.Rf6 Kg7?! (Stockfish17 and Dragon1 much prefer 20...c5!?) 21.Rc1 Ng8 (the engines fluctuate between this and 21...c5!?, but come to marginally prefer the latter) 22.Rcf1!? Nxf6 23.Rxf6? (23.exf6+ wins, according to the engines) Rg8? (Black probably has a slight edge after 32...c5, according to the engines) 24.Qf2 (missing 24.Nxg6!) Kh7 (Dragon1 prefers 24...c5, but Stockfish17 rates the two moves equally) 25.Qf4 Rg7 26.Nf3?! Rh8?! (the engines reckon 26...c5 gives at least the upper hand) 27.Nh4?! Qe8 (27...c5!? gives the upper hand, according to the engines) 28.g4?! Kg8 (Dragon1 prefers 28...c5!?, but Stockfish17 disagrees) 29.Qf3 b6 (29...c5!? is much preferred by the engines, and also 29...Qc8) 30.h3 Qe7 (again ...c5 is preferred).

From move 20 to move 30 the engines reckon Black'had up to nine chances to play ...c5 with good effect, but not one of those opportunities was taken even though the move is a logical follow-up to Black's 18th (..Rac8 makes no sense without ...c5 to come).
White is slightly better after 30...Qe7, despite being the exchange down, according to the engines, and went on to win, although only after mutual errors.
LESSON: chess is largely a logical game, and sometimes if A is played, then B had better follow.
