Thanks for running them. I put all these through Stockfish 7 multi-pv at 30 minutes/move before finalizing them.

This one:

[d] 1q4rk/R1nbp3/1n1p3p/QP1P4/3pPp2/2N2P1P/1P1N3K/5B2 w - - acd 29; acs 20; bm Nb3; c0 "Arasan-ipfreely, ICC 2016"; c3 "Nb3"; ce 0; id "arasan19.199"; pm Nb3; pv Nb3 d3 Nd2 Rg3 b3 Qg8 Qxb6 Rxh3+ Bxh3 Qg3+ Kh1 Qxh3+ Kg1 Qg3+ Kh1 Qh3+;

had h2h1 as another solution with not too bad a score but I think Nb3 is best:

1q4rk/R1nbp3/1n1p3p/QP1P4/3pPp2/2N2P1P/1P1N3K/5B2 w - - bm Nb3; id "cand13"; c0\
"Arasan-ipfreely, ICC 2016 (am Ne2)";

result: Nb3

I haven't looked at all of them but the 1st one Stockfish thinks e1e2 is best - maybe it is:
