I cannot see how the c pawn can be exploited, the a2 passer is way to strong.

Re: Who's Right?
I think after white plays kg5 followed by Ra7 white has some chances due to c7 being weak. Maybe I am missing something however.Robert Flesher wrote:AdminX wrote:I think white is winning due to the weak c7 pawn.Robert Flesher wrote:This would appear to be the critical line.

Re: Who's Right?
Black responds to Ra7 with Re2. Then the pawn can't be taken, even with check.AdminX wrote: I think after white plays kg5 followed by Ra7 white has some chances due to c7 being weak. Maybe I am missing something however.

Re: Who's Right?
Why not? I will have to check this when I have time. However if white's king is on g5 as I stated above taking on c7 with check looks fine I think. I could be wrong. I will look at it in detail when I have more time.zullil wrote:Black responds to Ra7 with Re2.
