The advantage of time

Post,M (2090) - King,M (1930) [A45]Queenstown chess classic (7.35), 21.01.2009

The position above is black to move. Black's queen is under attack and his pawn on d4 is also weak. Black is however better
The move I played in the game which gives white a chance to grab the pawn and have possible winning chances but after the better
Now White cannot take the pawn with the queen because the knight hangs but what happens if
Well this is the reason I titled this post the advantage of time. My initial analysis had the following forced line
22...Rad8 23.Rhd1 Rd7 24.Qb2 Red8 25.Ke3
The only move to keep the piece and I iniatially thought
25...Re8+ 26.Kf2 Red8 27.Ke3 Re8+ 28.Kf2 Red8 29.Ke3 Re8+
Is an easy draw and the best on offer for black, it turns out after a little more research into the position their is a nice shot with a very nice follow up.

I found this winning line 2 months after game.
26.Rxd4 Re8+! 27.Kf2 (If 27.Kd2 Qe6 28.Qc3 Qe2+ 29.Kc1 Rc8! wins the queen) 27...Rc8! 28.Kg3 (also losing is 28.Ke3 Rc2 29. Qb3 Qc7 the fork is unstoppable) Rc2 29.Qxc2 -/+ forcing white to give up his queen for whatever he can get.

13th World chess champion Gary Kasparov was a big fan of always going over old analysis because you never know what interestings things you may find with a fresh and deeper look.
