The recent post about the DCU Majors 2024 gave the Bartczak – Spence game as the most interesting, with plenty of play left in the final position. I thought Black “should be able to draw”, but the line I offered also left plenty of play. Delving deeper turned up some interesting points.
From the final position, I think best play goes 31. Rxc2 Ba6+! 32. Ree2! Rxe2 33. Rxe2 c5! (slightly more accurate than 33… Bxe2+ 34. Qxe2 c5 as I gave before, since then Black has to work out the consequences of 35. Qa6) 34. Kf2 Bxe2 35. Qxe2 a5 36. Qe8+ Kh7 , reaching the second diagrammed position.
An obvious idea for Black is to sit tight, maintaining the rook on the 6th rank, when it looks as if he has a fortress. But in fact it is not as easy as that.
