Subject: Are the following sacrifices from Movei-Amateur correct?

Author: Uri Blass

Movei lost 2 pawns against amateur I checked with yace only material to find
when it blundered and yace conclusions are that Movei blundered in Moves 17 and
27.

I checked later with Deep Fritz6 and Deep Fritz6 conclusions are that the moves
were the best moves and Movei blundered later

Here are the relevant positions

[D]r4rk1/ppp3pp/2nbpn2/1N6/3P3q/5B1P/PP3PP1/R1BQR1K1 b - - 0 17

Movei played 17...Rae8

Deep Fritz6 agree with that move but Yace says that Nd8 is better and not losing
material.

[D]2r1r1k1/6pp/2p1p3/B2p4/3Pnq2/3Q3P/PPR1RPP1/6K1 b - - 0 27

Movei played 27...c5

Deep Fritz agree with that Move but yace claims that Movei blundered when
Ra8 was the correct move.

I have to agree that the move that lost the game without chances was probably
28...Rxc5 that let Amateur to trade pieces and not only to win another pawn

Yace needs depth 12 to find it so it is not an easy move to find but the
question is if Deep Fritz is right by sacrificing a pawn by 27...c5(it is
clearly a sacrifice of Deep Fritz and not a blunder because I gave it a long
time.

Summery of the game is that Movei did 2 tactical mistakes or
sacrifices(dependent if you believe to Fritz or yace only material) and if you
believe to Deep Fritz6 it did 2 positional blunders(24...d5 and 28...Rxc5)

The position before d5 is here

[D]2r1r1k1/6pp/2pppn2/p7/3P3q/3Q3P/PP1B1PP1/2R1R1K1 b - - 0 24
