I just play simple chess. IMO from the position given I look at the
long term positional factors. I see an isolated pawn on c5 so my
first thought is how to attack it. I would play 1.b3 which frees up
the Bishop on c3 which now can roam freee and be one piece that can
attack the c5 Pawn from e3. Also Ra5 attacks it twice. Black is forced
to defend twice which ties down both rooks to the c file. THe White King,
after Bf1 can get to c4 which attacks the pawn 3 times winning it.
This leaves White with a passed pawn on b3. Certainly now b4 b5 is possible.
The White rook can now aim for d6 protected by the pawn at e5.
The combination of KRBB & passed pawn should Win.
