There is no surrender!
I vote for h4.
Your move bitcointalk. You have the white pieces

1.Nf3 d5 2.c4 e6 3.g3 Nf6 4.Bg2 dxc4 5.Qa4+ Nbd7 6.Qxc4 c5 7.O-O a6 8.d3 b5 9.Qc2 Bb7 10.Nc3 Be7 11.Bf4 O-O 12.Rfd1 Qb6 13.a4 Rfd8 14.a5 Qa7 15.e4 Rac8 16.h3 Nb8 17.Be3 Nc6 18.Qb3 h6 19.Ne2 Qb8 20.Rd2 Nb4 21.Bf4 Qa8 22.Ne5 Nd7 23.Nxd7 Rxd7 24.Qd1 Rcd8 25.Nc1 c4 26.dxc4 Rxd2 27.Bxd2 Bxe4 28.Bxe4 Qxe4 29.cxb5 Nc2 30.Nb3 Nxa1 31.Nxa1 Qd3 32.Nb3 Qxb5 33.Qc2 Qe2 34.h4 Bf8
I don't mind playing a few more moves to make the result clear. Proper technique in a winning position includes minimizing counterplay from your opponent. 34.h4 Rd3 would win material but 34.h4 Bf8 is even simpler as Rd3 (threatening both Rxb3 and Rf3) cannot be stopped and all checks and potential counterplay from white are prevented. If you are losing, seek complexity. If you are winning, seek simplification. I have time for a simple move like Bf8 because whites pieces are stuck passively defending each other. Neither whites knight or bishop can move without immediate loss of material.
