This feature allows you to anticipate an opponent’s move so that if he plays the expected move you can automatically reply with your next move. This speeds up the game dramatically especially in the case when engines are involved. He only ceased the “if/then” sequence when we reached a position where I had more than one good option.
I wanted to play openings offering tactical possibilities, but also wanted to avoid risky variations. Consequently, I played the King’s Gambit and not the Urusov Gambit (1.e4 e5 2.Bc4 Nf6 3.d4).
In both games I let the engine analyze until it reached 30-40 plies and again at the end of my opponent’s sequence of “if/then” moves the analysis was rechecked, but there was usually no change.
The King’s Gambit (I was white) fizzled out to an uneventful 27 move draw which when analyzed with Stockfish gave both sides a Weighted Error Value of nearly 0.00 (flawless). This indicates that Bersek and Stockfish were almost always in agreement on the best moves.
As black I though about answering 1.d4 with the Budapest Gambit (1.d4 Nf6 2.c4 e5), but in my experience black struggles to get back the P and white seems to end up with the better game. Still, I did not want to play a prosaic Queen’s Gambit, so chose the Symmetrical Defense (1.d5 d5 2.c4 c5). Oddly, it turned out to be a bit more involved that the King’s Gambit.
With Berserl by move 20 my opponent (white) was starting to register a slight advantage of 1/4 to 1/3 of a Pawn and my feeling was that we were nearing an ending and Berserk was starting to lose control so it was time to switch to Stockfish which gave a different evaluation...of nearly 0.00.
This game was also drawn in 27 moves.
Conclusion: For the average user Stockfish is still the best choice.

{D06: Queen's Gambit: Symmetrical Defense} 1. d4 d5 {The King's Indian offers active play with tactical opportunities, but I am not that well versed in its intricacies. One correspondence GM stated that objectively the KID has some serious problems in correspondence play. His advise was not to blindly trust engines in the opening. And, although the KID might be good OTB, in some lines white seems to do better and so it’s best to avoid the KID in correspondence play.} 2. c4 c5 {First described way back in 1604, this is sometimes called the Austrian Defense. It’s an uncommon variation that poses a purest test of Queen's Gambit. The question is whether black can equalize by simply copying White's moves. Generally it’s believed white should gain the advantage and the best black can do is draw.} 3. cxd5 {The most usual move is 3.Nf3, but other moves are playable and often lead to transpositions.} Nf6 {More popular is 3...Qxd5, vut there is lottle difference (either statistically or in evaluation) between the two moves.} 4.

Nxd4 a6 {Necessary to prevent the annoying Ndb5 attacking c7} (7... Bd7 8.

Consequently, I felt it was a good idea to switch engines and use Stockfish which gives white 1/4 of a P advantage.} Re5 21. Rc4 Kf8 {Making room for the other R at e8.} 22.
