A small Gothic Chess tournament with Bihasa 2.0, Gothic Vortex Nuclear Edition 2.2.5(private engine that i happen to have obtained, thanks Ed!) and myself, the great anti-computer in Gothic Chess player.
Time control is 40/15 repeating.
Bihasa from 0 points in the first 4 games it had great 3rd and 4th rounds.
Gothic Vortex had an awful time losing all 4 games.
I had my first loss against Bihasa with black.

Bihasa completely outplayed GV in the one game and the latter didn't have even a chance. The other game was more complicated but Bihasa managed with some good moves and unexpected for GV to obtain the advantage and win.
Here are 2 amazing wins of myself against Bihasa.
In the first i played a very good positional game sacrificing a bunch of Pawns(3) to obtain an active position and Bihasa a cramped one.
Yet, Bihasa was reporting scores in favor of itself of about +2.0 to +2.5.
And finally we reached an inevitable position(since Bihasa had to give material to release the pressure):
Bihasa played 41...Qd6 with a +2.48 score in favor of itself at ply 16.
I knew i was clearly winning.
I had an Archbishop and a Bishop against a Queen. That is enough to have the advantage. Combining this with the useless black Rook and it is easy to win. But Bihasa likes its Queen very much and rates it much more than Archbishop but i know that they are equal! So i was a Bishop up into a middlegame position and with a bad positioned black Rook, my win was inevitable.
The other nice game from round 1 was me winning with black against Bihasa. I gave a Bishop for a Rook for gaining tempos and while for the moment to my surprise Bihasa denied accepting it(interesting play!) but finally accepted it. After that i was much more active and managed to create an attack. It was tough but i won it in good manner finally playing some good attacking moves.
Bihasa again thought it is winning by reporting scores of +2.0 to +2.70 for itself. It realised it was losing when i played 34.Ri8 and from +2.52/11 went to +0.00/14 and 1 move later to -3.20/12. A huge fail.
But all these are nothing compared to the brilliancy in the game against Gothic Vortex with me having black.
GV reached to report scores of +14.0 and even +16.0(!!) for a dozen of moves. For about 20 moves it was reporting scores of +8.0 to +16.0(!!).
The plus scores started when i sacrificed a Pawn and a Chancellor for an Archbishop for 1 tempo and for the removing of this huge defender from his King's defense.
Then i sacrificed a whole Rook for another tempo! Tempos are extremely important in Gothic Chess when you have an attack. In this position i have to admit that the sacrifice was damn wrong as i didn't have any attack.
I.e, here i played 17...Nf6 giving a Rook for nothing but just a tempo.
After a while i gave a Knight for nothing also for opening lines to the King.
Here i was a Rook, a Knight and 2 Pawns down and white had the move. Gothic Vortex when i reviewed the game afterwards was very very happy with +10.5 score.
Of course it's a damn difficult position to defend for white, so i attacked and won.
I guess there is a proper defense that white can save the game but it's difficult to find in short time. Attacking is easier.And the above games. I will give all games after tournament finishes.
