2017-11-23 | 17:11:59 | Alfred Pfeiffer | P1343567 | problems | soltxt | update | Yoav Ben-Zvi: The first 2 moves of Try and Solution are by wR forcing decoy of bR to a position obstructing each of Black’s bishops allowing wR to play its third move without fear of being captured. If a bB is subsequently decoyed then wR exploits this by switching sides (left to right in the Try and right to left in the Solution). The Solution presents a third decoy of the bR (second obstruction of bBe1) followed by a fourth (bR abandons row 3) which wR exploits by again reversing sides playing a Switchback to f4 (1.R-f4 and 6.R-f4). In terms of logical structure the first 2 moves of the Try constitute a “main-plan” played in the Solution as moves 4,5 after a preliminary maneuver (“fore-plan”) that neutralizes the refutation (by decoy of bBd1). | |
