Comparing the merits/disadvantages of both boards.


Here's a side-by-side comparison of both initial moves.

Speculative Move: 9. a3 Bxc3

For the sake of this debate, we're assuming that cxd5 will be Ze's next (unforced) move.

  • In the Bd6 line, this capture is countered by forcing a Knight trade.
  • In the Bxc3 line, Ze is forced to recapture with his pawn or suffer a loss of material. It was suggested that Ba6 was the best move to make following this.

Speculative Move: 10. bxc3 Ba6
  • Ze completes the exchange by capturing our Knight, allowing us to pick up the pawn we lost with exd5, equalizing in material.
  • Here Ze makes his (assumed) cxd5 move, which forces us to respond with Bxd3 trading both bishops in a (now open) position. Bear in mind that if we respond 11. cxd5 exd5 12. Bxa6 is decisive, as White has another bishop on the board and this will force our other Knight to a6 to recapture (forced).

Speculative Move: 11. cxd5 Bxd3
  • Ze advances his Knight to e5, protected by his pawn (and blocking our d6 bishop), we can respond by Be6 (developing our bishop to the center .. see pic) or Bb7 (the long diagonal, covering our d5 pawn and our potential Nc6 move)
  • Each queen recaptures (Ze takes our bishop, we recover the e5 pawn) but Ze's next move could likely be 13. c4 .. forcing us to waste a move retreating our Queen (who is blocked in by our pawns), and then following with 14. Ne5, developing his knight to the center.

Speculative Move: 12. Qxd3 Qxd5

To be honest, I didn't even see the huge threat that cxd5 exposes in the Bxc3 line until I put this comparison together ... if there's another move that Black can make (aside from Ba6, which is flawed) then we need to analyze that .. because based on THIS information, Bd6 is clearly a superior move.

The only other alternative to 10. .. Ba6 I can see is c6, protecting from the cxd5 exchange, but this locks up our only bishop on the board, and also restricts our Knight moves to a6 and d7.

Ultimately, we maintain a stronger queenside pawn dominance in the Bd6 line (which is useful in the endgame, negligible in the middlegame), but strong Kingside pawns in the Bxd3 line (which, in this circumstance, is inferior).

  • Well I am convinced that saving the bishop is the thing to do. Any chance we can see a side by side comparison like this of Bd6 vs. Be7? I concede to the chess heavyweights who apparently have chess analysis software at their disposal. If onlythey would agree:) SalMancini
