kingside

Queen side. White has made a weakening move on the K-side, when maybe the other side (wing) of the board ought to have been his focus. Hence my suggestion: 16.b4

With this move, Black gives up a piece for two pawns. In effect a +5 advantage he has allowed to drop to a +4, but has simplified the game and exposed White's King to attack. That's the good cause. The 'tithe' was merely figurative language.... Work with me here.  

I bet the computer thinks it is mistake. But its probably the best move really, since you make a partial transformation of your massive rook advantage. Basically, when winning, you tend to want to avoid imbalances. Now black has more material and piece activity, so his position is more active no matter what.

I don't understand your question, Joe. At move 21, a Black Bishop, standing on this square (h3), moved away. What was to stop it coming back?

that was indeed an inspiring annotation by Ion. - Black's foresight beat White's play and how it came to the mate is nothing short of blissful at the end!

good game

Well played by Black, especially considering the rating difference.

Well done! enjoyed this game. The 2 players had a rating difference over 600. I watched the game and did not remember this. Like Jkarp said, it's great when you can learn from these annotations. It's good to ask questions, as the answers really help the novice players who would otherwise be lost. Thanks again I enjoyed seeing this game!
