In your Czech Benoni game, 12 h3 seems to be a big mistake -- wasting a tempo to encourage you to double up his pawns. Then your knight gravitates to a great outpost on f4 ( made possible by his doubled "f" pawns ). you grab his "h" pawn and make it count.
very nice, the way you conned him into invading your position with his R to g6. but then with B-g5 his Rook is trapped !
nicely done !
As I don't know how to annotate the game, I'll just talk about it down here. This is the worse of the two. I was black in a Giuoco Pianissimo. I make lots of inaccuracies, but no blunders and few mistakes. In the game I restricted my opponent on the kingside and center for much of them game, with nearly all play being on the Queenside for much of the game. Finally, my opponent blunders a pawn horribly, and I took advantage, winning the pawn and much more. After a lot of simplification we get into an endgame where I am up a bishop and 1 pawn I believe. He seemingly plays well until falling for mate.
