"Stage 3 of the world’s strongest computer chess championship TCEC has come to an end. Komodo is the winner of the stage with the amazing 11,5/18, a full 1,5 points ahead of competition. Komodo achieved 6 victories, 11 draws, and lost just one game to prove that its win in the previous stage was not a coincidence.
In a very close battle Bouquet, Houdini, and Stockfish shared the second position with 10,0/18. The silver medal of the stage goes to Stage 1 winner Bouquet with best tiebreak. The bronze is for the top rated engine in the field Houdini, while 4th place is for Stockfish, which is the only engine to achieve double victory in the stage.
Gull, playing with updated version 2.3, is at sole 5th position with 9,5/18.
The drama of Stage 3 was for the 6th position race, as the top six engines qualify to the next Stage 4 for a hexa round robin. Naum 4.6, Hiarcs 14, and Rybka 4.1 achieved 8,5/18. The tension was kept to the very end with the games Rybka – Gull and the 105 mover Houdini – Hiarcs in progress. In the end, Naum’s upgraded version for this stage had better tiebreak, and so it progresses on, while Hiarcs and Rybka are eliminated until the next season of TCEC."

Very interesting that three of the top engines Gull, Stockfish and Bouquet are freeware. And that Komodo has seemingly overcome Houdini as the top paid for engine. Of course there's another stage and a final between the top two. So Houdini could make a come back. However, even if Houdini ultimately prevails Komodo has certainly closed the gap and Bouquet and Gull are close contenders, right up there with Stockfish now at the top of the free engines.
It's remarkable that three of the top six are freeware and quite close to the paid engines. I doubt you'd lose very much using Bouquet, Gull or Stockfish as your main analysis engine.
