Try busting that blockade!

Solid. I did look at 20.Rg5, to see where that might go. It is not quite good enough, e.g. (sample line): 20...Bxg5 (20...Ng3 is as good) 21.hxg5 Ng3 22.Nxg3 ... (Bxg3!?) 22...fxg3 23.Bxg3 ... and White seems to have not quite enough attack for the material given up.

Of course, once you make the move, he is not obliged to take the draw - and, more importantly, the draw offer is automatically withdrawn! Though, just to be sure, I would point out that if I make the move the offer no longer stands. Having said all that, I think Black is relying too much on passive defence. Having made a gesture on the Q-side, I would have added a digit and played 22...b5!

I have just realised that my analysis on that comment is faulty - after 25. Rh3 Nf4 forks my two rooks and wins the exchange for him. I think if he did try b7-b5 I just keep files closed on the queen-side with c4-c5. But maybe he can play c7-c5 first?

Possibly White has a slight edge, but a breakthrough won't be easy to achieve. It's that bally blockade on the K-side that narrows White's avenue of attack. Black, on the other hand, isn't doing much of anything!

I don't remember where or when I first heard it, but I learned a long time ago that you need 2 attackable points to win. Only one point leads to draws being more likely. I'd say this game makes me a believer.

Another enjoyable annotation Charles, many thanks for talking us through your game.
