I came across an interesting game from Manitoba back in May. In it, the Black player missed a number of chances to put the game away, but, as so often happens, he was the last one to make a mistake and White seized his chance and won. There are some instructive positional inaccuracies to note as well. I think a lot can be learned from this one.

1. c4 f5 2. Nc3 Nf6 3. g3 g6 4. Bg2 Bg7 5. e3 {White hasn't chosen a very
ambitious setup, and his position almost seems like he is playing Black. The
plan isn't that bad though - it's just that Black gets very easy equality.} e5

King's Knight and castle before embarking on a queenside pawn expansion.} a5 8.

Na6 10. a3 Nc5 11. Qc2 {Now we see one of the problems with 8.Bd2. d3 is
undefended so Qc2 was required. Had the Bishop been back on c1, White could
have played b4 here with advantage.} d6 (11... a4 {trying to cement the Knight

trade Black's strong Bishop}) 22... Nh5 23. Rf3 Be6 24. d4 $2 (24. Nc3 Rb8 {
White may be able to hold but Black is definitely the one with all the chances

the b8-h2 diagonal. White can't take on g5 due to ...d5 and otherwise his
pawns will fall like dominoes}) 28. Rf2 d5 $6 {I can understand Black's
rationale behind this move, as he wants to take control of the e4 square, but
it actually helps White's cause since it gives him an extra point of attack -
namely the d5 pawn} (28... Ra8 $15 {followed by ...Rfb8}) 29. Bb4 $2 Rf7 (29...
