Volgende week de oplossing.
Oplossing vorige week:
Both bishops are under attack, so we need to keep enough material for mating.
What would win for us:
- rook vs. king
- two bishops vs. king
So what about 1. Rd8 ?
If black chooses to exchange we will have one of those winning endings. Even if he rescues his rook, we will have much less pressure and can savely pick up the a pawn. The resulting rook + 2 bishops vs. rook ending will again be won.
1. Rd8, Rd4+ 2. Ke3 and now Black can organize a further counterattack by 2. …, a2! 3. Bxa2, Ra4! White must counter-counterattck by 4. Bb3!, Rb4 (4. …, Ra3 5. Rd4+) and now nevertheless 5. Rd4+!!, Rxd4 6. Be7!, Rf4 (only square! the rook is trapped mid-board.) 7. Be6+, Kg3 8. Bd6! 1-0
