"Black, WFM Elizabeth Vicary, has just played the poor 25…f4? She had some pressure with the pawn on f5 threatening bxc4 and piling up on the c-pawn combined with a build up on the kingside. But, after this, Chris quickly took over the game with 26.cxb5 axb5 27.Ne1! threatening to drive Black back, which he did very nicely after 27…Ng6 28.Nd3 Qc7 and White took control from there."
This is absolute drivel. 25... f4 is not a weak move. Positionally and strategically, it's great-- keeps the center closed, creates the long term threat of ...f3, gains space on the kingside, controls g3, stops Ne3, keeps the white e pawn on e4 where it makes the Bb1 bad, and clamps down on the dark squares. If later I want to pressure the e pawn, I can play...f5, but I really don't see that I will ever (in a middlegame) want to open the position. LaRocca makes it sound like I'm releasing my pressure on white's center and killing my opportunity to play on both sides of the board. But the real story is that white's the one pressuring my center, and I need to keep the position closed or else I have no chance of orchestrating a kingside attack.
Now, Mr. LaRocca is correct that 25... f4 is not the best move-- 25... bxc4 is. If you are just looking at the game with a computer engine, this is the simple conclusion you would quickly come to: bxc4 = good, f4 = bad. In reality, black very much wants to play both moves, the only question is whether she can achieve this, and if not, which move is more important to play first. To determine this you have to correctly assess the situation after 25....bxc4 26. b4 Qsomewhere 27. exf5. And if you feed this position to Fritz 10 and Rybka (I used 26... Qc7, the second best move and the one I had been calculating in the game), you'll find the first engine assesses it at 1.28 and the second at 0.26. So I think it's not unreasonable to claim the situation is murky and the evaluation is tricky. My point is that the review presents 25... f4 as a bad move, when really it's a good move but for strategically complex reasons it's the second best move.
In your face, Boston.
