Go up one level in this thread


Analysis with the help of Hiarcs 7.32 on my Celeron 300A overclocked to 450 Mhz


POS 2 r2rb1k1/pp1nbpp1/1q2p2p/4B3/2BN4/1P6/P1P1QPPP/3R1RK1 w - - 0 1
Hiarcs 7.32 wants to refute the keymove with the line :
2. Nxe6 fxe6 3. Bd6 Bxd6 4. Qxe6+ Bf7 5. Qxf7+ Kh8 -+
is 3..Bxd6!? 4. Qxe6+ Bf7!? really good ?

POS 30 1r1rb1k1/5ppp/4p3/1p1p3P/1q2P2Q/pN3P2/PPP4P/1K1R2R1 w - - 0 1
Simply too hard for micro computer, the 4th (!) move of the main variation (c3!!
to expel the black queen from the a3-f8 diag is not easy to find even if you
start thinking at this position)

POS 42 2k1r3/1p1q1pbR/p2pn3/2pBpQ2/P3P3/1P1P1P2/2PB4/2K5 w - - 0 1
Hiarcs find a best than the solution move  Bg5 !! with a +3.00 advantage
the solution move Rxg7 give only +1.50 advantage

Here's the maine line of the correction :
2. Bg5 {3.00/17} 2... Nxg5 3. Bxb7+ {3.20/11} 3... Kc7 {2.71/13} 4. Qxd7+ {
3.02/13} 4... Kxd7 {2.71/12} 5. Rxg7 {2.70/12} 5... Ne6 {3.26/14} 6. Rxf7+ {
3.01/11} 6... Re7 {3.55/15} 7. Rxe7+ {3.26/12} 7... Kxe7 {3.01/12} 8. Bxa6 {
3.26/12}


Comment on other positions will come later ...
