The Trompowski with 2...c5 (Chess is Fun)
価格: ¥0
1.d4 Nf6 2.Bg5!?
An unusual and provocative choice. As the old saying goes, develop knights before bishops, but here, it's the bishop before the knight. The danger for White of course is that the bishop will now be subject to attack either by ...h6 or even from ...Ne4.
The Bishop's purpose is to capture or pin the knight and then to play e4. The upside for White is the possibility of immediate control over the center and the possibility of damaging Black's pawn structure after Bxf6. The downside for White is the high likelihood that Black will quickly gain the advantage of the two bishops for a long time, perhaps even the rest of the game.
2...c5
The move on which I have personally relied to defeat White's opening choice. Black immediately attempts to exchange the more flank c-pawn for White's central d-pawn, much as we see in openings as diverse as the Sicilian Defense, the Benoni, and the Symmetrical English. Here, there is an important additional advantage, the quick development of Black's queen towards the queenside, most often at b6 but don't overlook the occasional importance of a5.
Here , I have faced three moves from White:
A: 3.d5
An attempt to avoid the immediate exchange of pawns and with the idea of creating a broad pawn center with e4, but giving Black a choice between two reasonable options, 3...Qb6 (protecting the knight and pressuring the now unanchored b2 pawn), and my favorite response, 3...Ne4 (avoiding the capture on f6 and already hitting the bishop).
B: 3.Nc3
Quick development, but the knight move allows Black to capture on d4 when White somewhat prematurely recaptures with the queen. This variation is the most tactical line, with immediate and very complex play for both sides.
C: 3.Bxf6
The most common choice, nicking Black's pawn structure. Black will recapture with the g-pawn, opening the g-file but leaving no obvious, long-term destination for Black's king. Play in this line is dynamic. Black will usually continue with ...f5 to discourage White from playing e4, and with ...Qb6 pressuring b2.
