Re: Does anyones computer find RxH2
Hi Joseph
Using Stockfish 1.8 I came up with :-
1... Rxh2 2. Rxh2 Qxa3
3 bxa3 Bxa3+ 4. Kb1 Nc3+ 5. Ka1 Bb2+ 6. Kxb2 Nxd1+ 7. Kb3 Nxe3 *
[D]1k1r4/p1p5/2p1p3/4Ppp1/5P2/3Bn3/1KP3PR/8 b - - 0 8
However Qc5 seems better eg
1... Qc5 2. Qxc5 Bxc5 3. Bxe4 Be3+ 4. Kb1 Rxd1+
5. Rxd1 fxe4 6. Bg1 Bxg1 7. Rxg1 gxf4 *

Re: Does anyones computer find RxH2
I think it was meant as a best variation after Rxh2. Rxh2 is in Rainbow Serpent's movelist continuously near the top but never considered very long. Apparently not enough compensation to compete with Qc5, but that does not get a winning score so in the end it is still a positional decision, unless the score for Rxh2 is losing, have not really tried the move but I don't think it is losing?zullil wrote:mhurd wrote:
