[%c_effect a4;square;a4;type;GreatFind;persistent;true] A good move, preventing the b7-b5 pawn break.
1. e2e4  1... e7e5  2. f1c4  2... g8f6  3. d2d3  3... b8c6  4. b1c3  4... c6a5 Capturing the bishop is logical, but White gains good central control with the pawns on c4 and e4. It's hard to judge who benefits. Alternatively, Black can develop the bishop to c5, leading to play typical of the Italian opening, or play 4...Bb4 and maybe ...d7-d5 next. 5. d1f3 [%c_effect f3;square;f3;type;Interesting;persistent;true] An interesting development plan, tried in many games. The knight goes to e2, but only after the queen is placed on an active square. 5... a5c4  6. d3c4  6... d7d6  7. g1e2  7... f8e7  8. h2h3  8... e8g8  9. e2g3  9... c7c6  10. e1g1  10... c8e6  11. b2b3  11... d8d7 Both sides have played sensible moves, although I feel that Black should have looked for an alternative sooner, since White's position looks more comfortable.
