You should have sent me the game - this is blog material.
White misses the Rook & Knight back rank drawing pattern with mate
by a Knight in one corner. Mate with a Rook in the other.
(I've played this Knight and Rook draw in an OTB game.)
I've seen another pattern that also draws.
FEN
5k2/6R1/1p2pK2/1P2Nb2/2PP4/6P1/4r2P/5q2 w - - 0 50
[FEN "5k2/6R1/1p2pK2/1P2Nb2/2PP4/6P1/4r2P/5q2 w - - 0 50"]
50. Rf7+ Kg8 51. Rg7+ {Black cannot go to h8 due to Nf7 mate.} 51... Kf8 52. Rf7+ Ke8 53. Re7+ Kd8 54. Nc6+ Kc8 55. Na7+ Kb8 56. Nc6+ {And Black cannot go to a8 due to Ra7 mate.}
Whilst playing this out on my viewer I noticed the White b5 pawn.
It appears there are two ways to draw.

50. Rf7+ Kg8 51. Rg7+ Kf8 52. Rf7+ Ke8 53. Re7+ Kd8 54. Nf7+ {Not as neat as the previous example but this works.} 54...Kc8 55. Re8+ Kc7 56. Re7+ Kc8 57. Re8+ Kc7 58. Re7+ {The b5 pawn seals off the escape routes - this also draws}
Thanks to Stu for posting the game and to Greenpawn for the chess lesson on the rook and knight draw. I've seen quite strong and experienced players miss that drawing idea in OTB games, just because they've never seen it before and so aren't looking for it!
13....f5? Well I've gotta do something, prefer a quick and bloody end to being suffocated to death for 30+ moves. Maybe he'll nick the pawn instead of Ng5 & give me half a chance?
3. ... g6 was horrible. As a general rule, playing g6 and e6 early on (or g3 and e3 if White) is a bad idea in the opening because it leaves holes in your position which your opponent can take advantage of. Better to leave the e pawn back for a few moves until after you've castled. I think grabbing a pawn was a poor option for White, I would have done something like 6. Qe2 and then castled long.
If you like kingside fianchettoed bishops against 1.d4, then have a look at the Kings Indian Defence or perhaps the Grünfeld. The latter is currently Caruana's main weapon against 1.d4 - take a look at some of his games in the Gashimov Memorial tournament:

Thanks Data Fly, yes is was a ghastly move indeed . . . I'm thinking Nf6, e6 & b6 in future perhaps, but cheers for the link I will check it out tonight.
