Rxg6 Qxg6 now my main risk is that black will trade off the second rook the same way, so I tried to go back and forth, trying to make sure black rook is busy either guarding e6 or the a file 27.

47... Kg8 logical would be for black to take over the a file, but then I was hoping to generate enough pressure on kingside 47... Ra8 but then fritz finds a brilliant (but predictable) sac: 48. e6!!
