Stockfish Engines

[Chessqueen]

The overall strength of the later SF is very strong but the slow positional grind it plays allow humans to survive a few more moves than the previous ones. It seems like these versions play around with positional ideas before swooping down on its victims. Maybe this style of play is annoying for other engines to play against. Playing against the insanely strong tactical monsters sf 12 and previous versions did not allow humans that possibility. It was guaranteed crush within 20 moves. I thought that was very exciting.

Not really Stockfish has been the only engine that I tested that found 1. Nf3, therefore in losing by material it is the only program willing to sacrifice in order to get a Draw, besides LCO

I decided to let Stockfish play at 30 minutes per move or 1800 Sec per move, and it found the only move that Draw, for White, I wonder if Dragon 3.2 can also find 1.Nf3! using 1800 Sec per move
Note: After the first Move of 1.Nf3 you can change the time per move to only 5 Sec per move, and Stockfish will NOT have any problem blocking the position with pawns making it impossible for the Black side to make any progress with the Extra Queen .
After Stockfish finally found the only drawing move 1. Nf3! using 1800 per move, I decided to switch the time of only 5 Sec per move for the remaining of the moves, all of you noticed that the position became Blocked by pawns by sacrificing the Rook and the Knight

One thing is sure though, SF 13 and above versions, are excellent analysis engines especially with positions that does not call for tactical solutions.
