Default Evaluation of an endgame?

White: Kg1, Rd1, Rd2, pawns: h2, g3, f4, e5, c2, b2, a2
Black: Kc8, Rh8, Rc4, pawns: g7, g6, f7, c7, c6, b6, a7

White to move.

Can black draw this? How ought white to proceed?

Thanks!

FEN: 2k4r/p1p2pp1/1pp3p1/4P3/2r2P2/6P1/PPPR3P/3R2K1 w - - 0 1

It isn't really an endgame with so much material still on the board.

Specialist endgame analysers would baulk at the permutations in the full
game tree from this position. Freezer can do it for simpler positions
when guided by as many endgame tables as you can muster.

Can black draw this?


Not against best play.

How ought white to proceed?

Thanks!


Any of c3, h4 or even passive Kg2 will hold the win.

c3 looks to me like the most direct way of removing whites weak spots.

Fritz14(64bit) agrees with my assessment.

Basically as white you want to prevent black from doubling his rooks or
getting both of them pointing at h2 and then exploit your kingside pawn
advantage and his poor pawn structure by swapping a few of them off.

Once you have his rooks out of position and your king safe in pawns
doubling your rooks on the seventh rank is the classical way to finish
off an opponent. White just has to play carefully swapping off material
for equality when he can until his single pawn advantage really counts.
Obviously if you can turn it into a two pawn advantage then you do so.

And make sure your last surviving pawn is not a rooks pawn.
