No, I won't. Great comunity, but I'm not going to post anything on talkchess forum, because I don't accept its rules. Anyway I do not mind if somobody create a topic about my test on talkchess. On this forum I will provide a link to a download page, so everybody could download it.

Note sure what to think about this one.  Qg6 may hold the draw, but I will look into it further.
3r2kr/5qpp/2Q5/pp6/2pP4/B1n5/5PPP/2R1R1K1 b - - acd 48; acs 600; bm Qg6; ce -114; pm Qg6; pv Qg6;


I found nothing better than a draw for these two:
4k3/7R/p3N3/4P3/K1b2n2/3p3B/1p6/8 w - - acd 58; acs 600; bm Nc7+; ce 0; pm Nc7+;
pv Nc7+ Kf8 e6 Bb5+ Nxb5 axb5+ Ka3 b1=Q e7+ Ke8 Bd7+ Kxd7 e8=Q+ Kxe8 Re7+ Kd8 Rd7+ Kc8 Rc7+ Kd8;
8/1K6/6k1/2pp4/2p3P1/3p1P2/8/2R5 w - - acd 69; acs 600; bm f4; ce 0; pm f4;
pv f4 d2 f5+ Kg7 Ra1 c3 g5 c2 Kc6 d4 Ra7+ Kg8 Ra8+ Kf7 Ra7+ Ke8 Ra8+;

Despite the positive score, I think this is a draw also, considering the inability to make progress and the pv plan:
6R1/b4p2/6np/P2P1p1k/p6B/6PN/P1ppK1P1/1R6 w - - acd 61; acs 600; bm Rxg6; ce 111; pm Rxg6;

Sting is not too keen on Qg6, but b4 fares no better.
It is possible that Qg6 may hold and b4 might possibly draw, but it looks a little grim for both of them.

Neither one is all that helpful to decide if the outcomes are clear.  It will take very deep analysis to be totally certain of the outcome for these.

In my opinion only Qg6 draws. Also most engines choose b4 as first move then switch to Qg6. Sting can be not strong enough for this kind of position.

This one was taken from the internet. I thought what white wins, but now I'm not sure, maybe it's a wrong test position.

When I analyzed this, white was winning, but I'm not 100% sure now. It needs more analysis.
